I'm adding to the list of thank yous. I spent a lot of time searching for information. So many videos on how to set travel limits when the limits are only a little off, and hardly anything on when the adjustments aren't functional. This was perfect! Exactly what I needed to fix the limits after I had replaced the coupler on my 18 yr old Craftsman. Thanks! Thanks! Bless all the youtubers like you who post this stuff.
Thanks for the clear video. Your video helped me find an idea to adjust my open/close limits to my gate. Here is the story: I had my Liftmaster 5580 ( from 2006) "fixed" by technician. The "fix" hold for 1 day... The Tech guy said that my gear was gone, and it will cost 350$ to replace it!, he also brought a new LM80 for 820$! I didn't agree of course. So, I looked for videos on UA-cam and thanks for all the good people that filmed their fixing I was able to understand what is going on. First, I opened the motor back door and I looked carefully. My gear was as new! Then I followed this excellent video by +All-Pro Quality Garage Doors Inc. to have a start point. (2 minutes work time :) Now, my simple idea is to bring the the up and down limiters to their correct place by visual inspecting and manual rotating the screws. I disengage the gate and put a mark on the rail holder of the trolley once for the gate is closed position and another mark for open position to the height I want. Then I engage the motor to a learn position (2 clicks on the orange square button on the back of the motor, the the small light is blinking) The advantage at this mode is that every push on the remote controller is either moving up or down, so I can adjust the trolley position. So, I brought the trolley to the up position and then my simple contribution to the solution is to rotate the up limiter with a flat screwdriver until its metal contact is touching the metal in the middle wide limiter gear, while I am with the motor back cover open so I can see exactly the movements and where and how much I should rotate (no more guessing...) The same I did for the down position. Then I engage the trolly to the gate, start another learning mode and there it was fixed! (at list 2-3 times up and down with learning mode so this motor can adjust itself to the force required. (The blinking light is stooped when the engine did it learning job successfully). I hope this will help someone with the same annoying problem.
Absolutely an amazing quick fix to a frustrating problem. Many, many videos show how to change the drive gear and all of them fail to show your technique on how to adjust the limiters. They skip over that part of the repair and leave you wondering what it is you did wrong when the door won't stay down. Your video hits the nail on the head. BRAVO. Thank you very much!!!!
I agree! it is something often skipped over that leads you back to thinking you've screwed something up and often times ending up having to call someone to fix it when that's exactly what you were trying to avoid in the first place!!!! Glad you found the solution and got it taken care of. 👍🏽👍🏽
Thank you so much for creating this video! Had the issue with my garage door and couple of reputed companies just declared the Garage motor dead. However, I decided to open the cover and found that travel module clip was loose. This video helped me fix the issue and now its working again... on the same motor !!! Thanks Again !
THESE GUYS ROCK!! If I lived anywhere near Santee, CA and I needed garage door repairs they'd be my FIRST call! Following their excellent videos I was able to swap my gear and sprocket assembly and then when I couldn't get the travel right I followed this video to the letter and after the recommended adjustments my 1994 era Liftmaster works like a champ. Thank you All-Pro!
Thank You! Thank You! Thank You! After replacing the sprocket on my garage door, it was completely out of adjustment. The darn thing nearly ripped the track off the wall mount. I came very close to throwing in the towel until I found your video.
Great video! I've watched a bunch of videos and this is the only one that has tackled this topic. PS: I turned off the sound because the music is terrible.
Thank you for this video! I could not for the life of me figure out why the garage wasn't functioning after swapping out the gear & sprocket. Followed your steps and worked like a charm.
After I changed sprocket when I tried to close the garage door it came back up after it hit the ground. I was clueless and going to pay $$$ to fix until I saw this video and decided to give a last try. This video saved me $, time and effort. Thanks a lot!
I just wanted to say thanks for making this video and your other one on the gear swap. I already had my drive gear out and was waiting on parts. Decided to do a little search and see what I could find when I came across the gear swap video. I hadn't even thought about the limit switches or locking my chain in place. Your video saved me some stress as I knew I had to figure out the end points before replacing the gear and chain. It was no big deal, but it could have been a mess. So you saved me a bunch of time and I now have a pretty good understanding how these units work. 7$ in parts vs 200$ for a new unit or much more for a garage door service to come out.
GREAT VIDEO! I found myself needing to accomplish this after I replaced a broken belt. In following the video I also discovered what was probably the root cause of the belt breakage. In this case it was the retainer clip holding the odd shaped gear in place was missing. (not sure we it went) Since I saw that it was actually a low stress situation so I simply used a tiny zip tie. All in all, I'm a happy dude that saved money, and the door now shuts softly, and on the up limit side doesn't hit the stop. Did I say Great Video, and of course a huge THANKS!
Thanks so much for your quick response, After following your suggestions I learned that my problem was in my RPM sensor on my LiftMaster 1300. When I replaced my worn sprocket I inadvertently mis-aligned/dislodged the RPM sensor pinwheel located on the end of the motor shaft, thus disrupting the infrared signal to my circuit board. Again, thanks for your invaluable information and I hope my experience will help another fellow DIY'er in our quest to save a buck!
This is the best video, I watched a lot of video they never showed you all this detail. I really appreciated. It helps me a lot. I already gave up. But last minute when I saw this video I fix my garage. Wonderfull video. Thank you
Thank you so much. I was knocking my head against the wall trying to figure out what I possibly did wrong when I replaced the sprocket assembly. When I came across your video, it was just what I needed; something so simple but I would not have known based on any written directions.
Joe Serao I hear ya Joe! It took me a few yrs before I realized i could make a video of this and attach it to the end of my gear and sprocket video and avoid having to answer the same question over and over, its very hard to explain it but when you can watch it on a video its so simple it makes you laugh!!!
The ONLY video that helped me nail down the problem of my Sears Craftman door opener and solve it. I'm a layman and don't get too many opportunities to congratulate myself😀Thanks Mike for the video.
Thank you so much for this AWESOME video. I'm not very handy and need instruction like this. I switched out the sprocket gear but the door was haywire and the adjustment screws were not working. Just by looking at the still frame at about 1:30 in... I could tell that my yellow wired sensor had fallen off the white "up" screw. I got it back on and then followed your instructions to the letter with the hand adjustments. It wasn't anytime at all that I had the door functioning perfectly. THANKS AGAIN!!! You not only saved me money but also helped give me a great sense of accomplishment.
That’s fantastic news Kathy! I know how you feel, I use youtube all the time to research products and figure out how to fix things I’m not familiar with and it works, I get things fixed! Glad now to have an opportunity to pass it forward!! 👍🏻👍🏻
I want to thank you for coaching me thru this repair. Following your instructions definitely helped. But I would like to suggest you add narrative to this video, it’s very hard to read and then follow your steps by reading at the same time. Thanks for the video.
Thanks buddy I was having a hell of a time trying to adjust it kept running out of adjustment. and I found your video I would have never thought of removing the gear to adjust it worked great thank you so much for your video
Thank You!!! My drive sprocket broke and I replaced it just fine. The problem was the up an down adjustment limits were out of range.Your video saved me a lot of time trying to figure it out.
Thanks Mike for making this video! I had to help someone with this exact issue last week after there gear swap. Now if they are having trouble with the instructions I have given them, I can link this video to them!
I had the same problem Joe, a lot of folks who do a gear swap get their limits messed up and explaining this method over the phone or in comments and emails was just way too hard...it needs to be seen.
Excellent video! My limit sensor was actually in pieces when I took the opener apart, but everything snapped back together and I was able to adjust it using your instructions.
Thank you so much for this video. I needed to understand how this assembly worked because I screwed it all up. You saved me a lot of time, money and for that I can't thank you enough.
What can I say ... this video was just the thing I was looking for... the down travel is perfectly fine. However the up travel still doesn’t come back up all the way . But whatever so far is miles better than what it was at ...
Greeeeat video! After replacing the gear, i thought i was done when door wasnt working properly! Your video is exactly what i needed! Saved the day bro!
All-Pro Quality Garage Doors Inc. Boooyah right back atcha! Hey so i greased up the plastic gear and worm gear with the entire grease packet, and made sure to get it. in the teeth, but after running it it seems like theres not that much grease in there. How heavy is it supposed to be greased up (not that i have any left) and are u supposed to grease the shaft of the gear and sprocket? (Because i didnt and would dread taking ut apart again)
NoJustass NoPiece no your good just using most if not all the packet, when you first run it it will spit alot of it out but thats ok, maybe recheck it in 5-7 yrs and make sure the chains not too tight and your good to go!
How do I get the trolley in the center of the rail? Do I pull down on the red cord and then hit the garage button on the wall? Also, once the adjustment are made, will this help with my issue of the garage door hitting the stop bolt and when closing the door comes back up? Any help is much appreciated. Your videos are very helpful.
@@ALLProGarageDoors I appreciate your response and videos. Everything is working again. Again thanks for your response. Keep those videos coming, they are very helpful!!!
Searched but missed this until after I fixed a problem. I found my "Straight Door Arm" bent and the trolley at the wall end of the T rail. After disconnecting the door, the trolley would only travel about a foot then shut off. After looking at several other possibilities including the speed sensor that others suggested, I looked inside the housing and noticed the traveling limit switch contact was near one end of the drive screw. I adjusted the drive screw to put the moving limit switch in the middle just like this video shows. Then I adjusted the down and up limit switches about an inch from the drive screw and operated the trolley (without the door attached) to determine if I had the limits approximately correct. At this point, I could have adjusted the travel limit screws if I needed to, but I was close enough to correct that I decided to attach the door and run the opener again. A couple of adjustments of the down and up limit screws and both the open and closed positions were good. The cause of my initial problem was probably that the down limit did not make contact and the motor kept running, causing the nylon drive screws to flex and its gear disengage. I may need to replace the limit switch drive assembly if the drive screw loses its position again. I also need to reduce the down force because the straight arm was bent when the opener malfunctioned.
B Wilson yea, always do the testing on a light force control, ck the limit contacts, make sure they are clean maybe hit em up with some real fine sand paper.
I fucking love UA-cam. I had this issue after my chain fell off, I replaced the chain and trolley assembly, followed this video and BOOOOOOOOOOOM!! Thanks mate
So, I am installing a 1979 vintage GDO that has the chain and trolley completely disassembled from the t-rail and also the travel limits were randomly set all over the palace and most likely do not correspond to any position of the motor. However, BEFORE I attempt to "fine tune" the travel limits per your video, I need to "synch" the chain trolley position to correspond to the motor's fully closed position and for that I need to keep the limit switch from interfering (I think ...) with the chain/trolley travel. Do I need to have the DOWN limit contacts (brown wire) set to a position far enough away from the center contact (gray wire) so that the chain can engage the inner trolley BEFORE the limit switch DOWN contact shorts to the CENTER contact? Or does it NOT matter where the down contact is set? Or, should I DISCONNECT and REMOVE the travel limit switch all together during the initial motor-chain synch? If I do the latter, with the limit switch removed, will the motor keep trying to move the chain even farther after the trolley engages? TIA for any reply.
i wouldn’t disconnect the limits, if the limit is close to the down then bring the inner trolley close to the down position then engage the door and fine tune it.
Mike, the top of my chain gear sheared off and the chain got all twisted up. I replaced the gear assemble using your video. It was very helpful. I had to wrestle the chain back on and readjust it. Now when it runs there is a clicking sound from the gear at the top of the unit. I noticed the chain on the right side of the rail as you face the garage door is slight torqued. I think that is what is causing the clicking sound. How can I fix it? Thanks for your help.
Steve Malone Hi Steve...back before the invention of the chain spreader I would get a clicking sound on a lot of machines, sometimes it's because the chain was too tight, other times...too loose, and sometimes there was no way to get rid of it, you just hoped that after a few months it would go away. The noise is caused by the chain not feeding on the sprocket perfectly. Try "slightly" loosening the chain and see if it gets quieter or louder, if it gets worse then go the other way and tighten it some more, one way or the other usually makes an improvement. Try to get it as quiet as possible then let it go for a few months and see if the sprocket wearing in lets it quiet itself on its own, if not then try the same adjustments again.
Great Video! The gears were all out of whack on my Liftmaster opener after the plastic sprocket coupler broke. It would be cool if you could link this video to that problem. Once again, nice job - thanks for posting!
@@ALLProGarageDoors I followed your tutorial which had me up and running within 15 minutes! Without your video, I would have been at a total loss! THANK YOU!! 👍😊
Great video on re-setting limits after changing out gear sprockets. I set the close (1/2 HP Craftsman) perfectly; however the open repeatedly hits the stop screw and when I watched the limit tabs with the cover off it made contact well ahead of where it stopped, meaning when the tabs made contact during opening, it never stopped. I checked and the wiring was intact from the limit tab to the circuit board. Any ideas? Do I need a new board?
Jim Willis I had one the other day doing just that... i sanded the contacts and put a drop of wd-40 on it and it worked fine. Not sure for how long.... but worth a shot.
I'm at my wits end. I repaired and replaced my sprocket, adjusted and reset the limits per your video, which is outstanding, and believe me I've checked out a few before finding yours. However, when I run the LiftMaster it only tracks approximately 12-15 inches down and then returns to the center position. I have not attached the door to the rail train because I am afraid of damaging my door. Any suggestions?
depending on the year of the machine, when it comes back up to a stop it should flash you a code from the LED light on the back of the machine telling you whats wrong depending on the number of flashes.
I did a gear swap and did your adjustment but when the contacts come together nothing happens, the door keeps going until it hits the stops. I even unhooked the yellow wire and connected it to the grey wire and still it didn't stop. I clearly have another problem. Do you have any idea what it could be?
Thanks for the video! Where can I buy these gears? The gears in my 1/3 HP are worn out. I need to replace them. I couldn't find these parts from homedepot or amazon.
Hello and thank you for the great video. I got my 1991 Craftsman 1/3 HP opener to work after putting the new gear on it but it stops about 4 to 5 inches from the garage floor and immediatley goes back up without stopping. With the cover off I notice that the down limit does not make contact with the other metal piece, it stops about 1/4 inch before hitting the contact and then reverses its travel as the garage door goes up. In order to keep the garage door from going back up I had to adjust the limiter so it touches the contact right at the point of where the door goes back up in order to keep the door closed (so there is about a 5 inch gap between the floor and the bottom of the garage door). Any ideas on what is causing this to happen and what I can do to fix it?
The beams are okay and the force control is turned all the way up. Is it possible that when the spring broke (that is when all of my grief with the opener started) it did some damage to the opener's motor? I replaced both springs and checked the tension on both of them. The door closes completely to the floor when I close it manually; the tracks are clear and they operate smoothly. For the life of me I can't figure out why I cannot get my opener working properly.
It's probably something simple, check the plastic notched wheel at the end of the motor shaft and make sure that it's pushed all the way on to the shaft, one guy in the comments said his wheel was loose or off, if its off your machine won't travel more than 6 inches if it's too far back on the shaft it could cause the problem you are having. operate the door down then let it reverse and come back up then count the number of flashes the LED light on the back of your machine gives you...it's giving you a code as to whats wrong. it will be a sequence of flashes from 1 to 6. but push the slotted opto wheel all the way snugly on to the shaft first and make sure the small circuit brd that reads the opto wheel is on snug as well.
Very...very doubtful that your door springs are causing this. One more thing you can try that might sound kind of strange but spray the back side of the wood jambs and or wood trim (on the outside... that your door travels down) with silicone or WD-40 if you see any burn marks your door has left on the back side of the wood from rubbing...do this first before ANYTHING else.
Mike... my sprocket snapped when the door was closed and my trolley is close to the opening of the door. I replaced the gear/sprocket.....In adjusting my limits how do I move the trolley to the Center? When I go to open the door the trolley travels about a foot into the garage and then stops and travels back towards the opening of the garage. I am guessing that I need to remove my repaired sprocket/gears an then manually move the chain and trolley to the middle prior to adjusting the limits. Any help would be greatly appreciated. Thanks
+Dodger Fan Yes...loosen the chain, remove it from the sprocket and manually rotate the chain until you are in the center of the rail then do the same with the limit assy gear and fine tune from there.
+All-Pro Quality Garage Doors Inc. Mike...finished the Gear replacement and adjusted the limits. I have to thank you for providing great info and enabling me to do the repair. Saved me some $$, total cost of fix was $28...haha. I am so stoked!!! Thanks again....
My new gear drive seems to be working properly but the motor will only move in the up direction until it hits the stop screw. Is this a limit problem or did something go wrong when I installed the new gear drive? Why wont it go in the opposite direction back down. Bad wiring?
rmgrip88 did you reconnect your safety eyes? If you hear a clicking sound ten times after the opener is activated to go down then its safety beams. Make sure the opto-wheel is tight on the end of the motor shaft and that the rpm sensor brd is on tight.
I replaced the gear and sprocket in a 1/3 HP Craftsman. After replacing, the door will only travel a foot or so and then return to where it started. In looking at the limiter screws and the center screw, the door doesn't travel to either of the limiters. Any thoughts would be appreciated.
Thanks for that. I pulled the wheel off and put it back on and unplugged and plugged the RPM sensor back in and all is well. I hadn't connected one of those correctly. Thanks so much for responding and for making the videos.
Thanks so much !! I did a gear swap and the limit switch was maxed out after I tried to adjust it. I took it apart again and thought I broke it. I snapped it back in , followed your video and it works like new !! Thanks again !!
So I followed your instructions. However my issue is my trolley will only move 1 foot forward 1 foot backward. So I moved it to the middle of the rail and it will only go like 1 foot and then returns one foot. I have the limits suggested just like you showed in the video. Any ideas? I did replace my gear and that's when I had this issue arrive. Thanks for any help!
All-Pro Quality Garage Doors Inc. Freaking genius dude! That is exactly what it was. I took it off and was turning to the shaft with a pair of vise grips to get the trolley where I wanted it. Bingo! Thank you so much man!
Saved me today,. I didn’t know how bad it would get out of alignment just by changing the chain gear and shaft. Thank you very much.

I had the same problem Joe, a lot of folks who do a gear swap get their limits messed up and explaining this method over the phone or in comments and emails was just way too hard...it needs to be seen.
Thank you very much for posting this video. Great video. Helped fix the issue I was having.
Excellent video! My limit sensor was actually in pieces when I took the opener apart, but everything snapped back together and I was able to adjust it using your instructions.
Excellent!!! Glad to hear it! 👍🏽
Thanks for the video. I adjusted mine and now it's working. You saved me hundred dollars, cheers!
Fantastic!! 🍻
Thank you so much for this video. I needed to understand how this assembly worked because I screwed it all up. You saved me a lot of time, money and for that I can't thank you enough.
+bowser0798 ....You just did Bowser!!! Glad to help out!
I commend you sir!!!! I don't know what I would have done without finding this video!!!!
Glad to help out!! 👍🏽
What can I say ... this video was just the thing I was looking for... the down travel is perfectly fine. However the up travel still doesn’t come back up all the way . But whatever so far is miles better than what it was at ...
Greeeeat video! After replacing the gear, i thought i was done when door wasnt working properly! Your video is exactly what i needed! Saved the day bro!
NoJustass NoPiece booya brother! Glad to be able to help out, its a simple adjustment but people overlook it often.
All-Pro Quality Garage Doors Inc. Boooyah right back atcha! Hey so i greased up the plastic gear and worm gear with the entire grease packet, and made sure to get it. in the teeth, but after running it it seems like theres not that much grease in there. How heavy is it supposed to be greased up (not that i have any left) and are u supposed to grease the shaft of the gear and sprocket? (Because i didnt and would dread taking ut apart again)
NoJustass NoPiece no your good just using most if not all the packet, when you first run it it will spit alot of it out but thats ok, maybe recheck it in 5-7 yrs and make sure the chains not too tight and your good to go!
Great job, exactly the fix my LiftMaster needed, thanks a ton!
Awesome subtitle ( after I screwed them up) was EXACTLY where I was. Thanks. My 27 year old opener working like new
anthony kayson excellent!! Simple fix and up and running!
How do I get the trolley in the center of the rail? Do I pull down on the red cord and then hit the garage button on the wall? Also, once the adjustment are made, will this help with my issue of the garage door hitting the stop bolt and when closing the door comes back up? Any help is much appreciated. Your videos are very helpful.
yes to all questions. when your testing it leave the cover off so you can see whats going on inside.
@@ALLProGarageDoors I appreciate your response and videos. Everything is working again. Again thanks for your response. Keep those videos coming, they are very helpful!!!
@@rodrobinson6111 Thank Rod… appreciate it.
Thank you. Saved me $120 +
Another grateful watcher. Great video. Many Thanks.
Thanks Alex!! Hope the vid helped!
Thank you very much. Replaced the gears and everything was off.
Thanks for this clear video, that helped me so much
Thank you so much for this video. Worked for me.
Searched but missed this until after I fixed a problem. I found my "Straight Door Arm" bent and the trolley at the wall end of the T rail. After disconnecting the door, the trolley would only travel about a foot then shut off. After looking at several other possibilities including the speed sensor that others suggested, I looked inside the housing and noticed the traveling limit switch contact was near one end of the drive screw. I adjusted the drive screw to put the moving limit switch in the middle just like this video shows. Then I adjusted the down and up limit switches about an inch from the drive screw and operated the trolley (without the door attached) to determine if I had the limits approximately correct. At this point, I could have adjusted the travel limit screws if I needed to, but I was close enough to correct that I decided to attach the door and run the opener again. A couple of adjustments of the down and up limit screws and both the open and closed positions were good. The cause of my initial problem was probably that the down limit did not make contact and the motor kept running, causing the nylon drive screws to flex and its gear disengage. I may need to replace the limit switch drive assembly if the drive screw loses its position again. I also need to reduce the down force because the straight arm was bent when the opener malfunctioned.
B Wilson yea, always do the testing on a light force control, ck the limit contacts, make sure they are clean maybe hit em up with some real fine sand paper.
I fucking love UA-cam. I had this issue after my chain fell off, I replaced the chain and trolley assembly, followed this video and BOOOOOOOOOOOM!! Thanks mate
Gotta love UA-cam!!!
So, I am installing a 1979 vintage GDO that has the chain and trolley completely disassembled from the t-rail and also the travel limits were randomly set all over the palace and most likely do not correspond to any position of the motor. However, BEFORE I attempt to "fine tune" the travel limits per your video, I need to "synch" the chain trolley position to correspond to the motor's fully closed position and for that I need to keep the limit switch from interfering (I think ...) with the chain/trolley travel. Do I need to have the DOWN limit contacts (brown wire) set to a position far enough away from the center contact (gray wire) so that the chain can engage the inner trolley BEFORE the limit switch DOWN contact shorts to the CENTER contact? Or does it NOT matter where the down contact is set? Or, should I DISCONNECT and REMOVE the travel limit switch all together during the initial motor-chain synch? If I do the latter, with the limit switch removed, will the motor keep trying to move the chain even farther after the trolley engages? TIA for any reply.
i wouldn’t disconnect the limits, if the limit is close to the down then bring the inner trolley close to the down position then engage the door and fine tune it.
Mike, the top of my chain gear sheared off and the chain got all twisted up. I replaced the gear assemble using your video. It was very helpful. I had to wrestle the chain back on and readjust it. Now when it runs there is a clicking sound from the gear at the top of the unit. I noticed the chain on the right side of the rail as you face the garage door is slight torqued. I think that is what is causing the clicking sound. How can I fix it? Thanks for your help.
Steve Malone Hi Steve...back before the invention of the chain spreader I would get a clicking sound on a lot of machines, sometimes it's because the chain was too tight, other times...too loose, and sometimes there was no way to get rid of it, you just hoped that after a few months it would go away. The noise is caused by the chain not feeding on the sprocket perfectly. Try "slightly" loosening the chain and see if it gets quieter or louder, if it gets worse then go the other way and tighten it some more, one way or the other usually makes an improvement. Try to get it as quiet as possible then let it go for a few months and see if the sprocket wearing in lets it quiet itself on its own, if not then try the same adjustments again.
Thanks buddy you saved my bacon.
Hi - so I removed my chain and unsure what cycle the opener was in , will this work for installing the chain also?
yes it will, put the trolley somewhere near the middle and match it with the gears and you’ll be real close then just fine.
Great vid thanks , would not of been able to do that tuning without your vid . thanks again
Glad it worked out for you Stanley!!
Great Video! The gears were all out of whack on my Liftmaster opener after the plastic sprocket coupler broke. It would be cool if you could link this video to that problem. Once again, nice job - thanks for posting!
Peter Newman Thanks Pete! I’ve got it linked to the very end of the gear & sprocket video where I hope folks can find it. Glad it worked out for you!
Great video , no bullshit to drive people up the wall , well done .
Thanks James!
THANK YOU!! Great find due to being in a bind. Exactly what I've been trying to find. P.S. The thumbs down on this video are cluless. Thanks again! 👍😊
Thanks Rapa!
glad the video helped you out! 👍🏽
@@ALLProGarageDoors I followed your tutorial which had me up and running within 15 minutes! Without your video, I would have been at a total loss! THANK YOU!! 👍😊
Great video on re-setting limits after changing out gear sprockets. I set the close (1/2 HP Craftsman) perfectly; however the open repeatedly hits the stop screw and when I watched the limit tabs with the cover off it made contact well ahead of where it stopped, meaning when the tabs made contact during opening, it never stopped. I checked and the wiring was intact from the limit tab to the circuit board. Any ideas? Do I need a new board?
Jim Willis I had one the other day doing just that... i sanded the contacts and put a drop of wd-40 on it and it worked fine. Not sure for how long.... but worth a shot.
I'm at my wits end. I repaired and replaced my sprocket, adjusted and reset the limits per your video, which is outstanding, and believe me I've checked out a few before finding yours. However, when I run the LiftMaster it only tracks approximately 12-15 inches down and then returns to the center position. I have not attached the door to the rail train because I am afraid of damaging my door. Any suggestions?
I would check your force control settings and make sure they are not set too light and make sure your chain is not too tight.
depending on the year of the machine, when it comes back up to a stop it should flash you a code from the LED light on the back of the machine telling you whats wrong depending on the number of flashes.
Good video, but it would be nice if you showed a little bit more about adjusting the pressure once you get the up and down limits set.
I did a gear swap and did your adjustment but when the contacts come together nothing happens, the door keeps going until it hits the stops. I even unhooked the yellow wire and connected it to the grey wire and still it didn't stop. I clearly have another problem. Do you have any idea what it could be?
follow each wire into the wiring harness, make sure they are tight in the harness and the harness is snugged down.
Thanks for the video! Where can I buy these gears? The gears in my 1/3 HP are worn out. I need to replace them. I couldn't find these parts from homedepot or amazon.
Chao Liu you could call our shop and ask for Paul, he might be able to ship them to you
Hello and thank you for the great video. I got my 1991 Craftsman 1/3 HP opener to work after putting the new gear on it but it stops about 4 to 5 inches from the garage floor and immediatley goes back up without stopping. With the cover off I notice that the down limit does not make contact with the other metal piece, it stops about 1/4 inch before hitting the contact and then reverses its travel as the garage door goes up. In order to keep the garage door from going back up I had to adjust the limiter so it touches the contact right at the point of where the door goes back up in order to keep the door closed (so there is about a 5 inch gap between the floor and the bottom of the garage door). Any ideas on what is causing this to happen and what I can do to fix it?
Has to be either I-beams or force control, turn up the down force a number or two.
The beams are okay and the force control is turned all the way up. Is it possible that when the spring broke (that is when all of my grief with the opener started) it did some damage to the opener's motor? I replaced both springs and checked the tension on both of them. The door closes completely to the floor when I close it manually; the tracks are clear and they operate smoothly. For the life of me I can't figure out why I cannot get my opener working properly.
It's probably something simple, check the plastic notched wheel at the end of the motor shaft and make sure that it's pushed all the way on to the shaft, one guy in the comments said his wheel was loose or off, if its off your machine won't travel more than 6 inches if it's too far back on the shaft it could cause the problem you are having.
operate the door down then let it reverse and come back up then count the number of flashes the LED light on the back of your machine gives you...it's giving you a code as to whats wrong. it will be a sequence of flashes from 1 to 6. but push the slotted opto wheel all the way snugly on to the shaft first and make sure the small circuit brd that reads the opto wheel is on snug as well.
Very...very doubtful that your door springs are causing this. One more thing you can try that might sound kind of strange but spray the back side of the wood jambs and or wood trim (on the outside... that your door travels down) with silicone or WD-40 if you see any burn marks your door has left on the back side of the wood from rubbing...do this first before ANYTHING else.
just a great video, well done
Joe Bilhete ....... Thanks Joe! Hope it helped.
your a life saver, just brilliantly done without all the long BS speeches Thanks again.
Thank you, thank you, thank you! This was exactly what I needed.
LifeIs Free glad to help out! 👍🏻
Mike... my sprocket snapped when the door was closed and my trolley is close to the opening of the door. I replaced the gear/sprocket.....In adjusting my limits how do I move the trolley to the Center? When I go to open the door the trolley travels about a foot into the garage and then stops and travels back towards the opening of the garage. I am guessing that I need to remove my repaired sprocket/gears an then manually move the chain and trolley to the middle prior to adjusting the limits. Any help would be greatly appreciated. Thanks
+Dodger Fan Yes...loosen the chain, remove it from the sprocket and manually rotate the chain until you are in the center of the rail then do the same with the limit assy gear and fine tune from there.
+All-Pro Quality Garage Doors Inc. Mike...finished the Gear replacement and adjusted the limits. I have to thank you for providing great info and enabling me to do the repair. Saved me some $$, total cost of fix was $28...haha. I am so stoked!!! Thanks again....
Excellent! Job well done Dodger fan!!
My new gear drive seems to be working properly but the motor will only move in the up direction until it hits the stop screw. Is this a limit problem or did something go wrong when I installed the new gear drive? Why wont it go in the opposite direction back down. Bad wiring?
rmgrip88 did you reconnect your safety eyes? If you hear a clicking sound ten times after the opener is activated to go down then its safety beams. Make sure the opto-wheel is tight on the end of the motor shaft and that the rpm sensor brd is on tight.
@@ALLProGarageDoors thanks! That was it... one of the wires came loose during the install
Just to be clear, the arm should be disconnected from the trolley first or can it be left on?
disconnect until ready to fine tune it… or just keep the force control settings real light.
I replaced the gear and sprocket in a 1/3 HP Craftsman. After replacing, the door will only travel a foot or so and then return to where it started. In looking at the limiter screws and the center screw, the door doesn't travel to either of the limiters. Any thoughts would be appreciated.
Mark Hallman you might have forgotten to put the opto-wheel back on the motor shaft.
Thanks for that. I pulled the wheel off and put it back on and unplugged and plugged the RPM sensor back in and all is well. I hadn't connected one of those correctly. Thanks so much for responding and for making the videos.
Mark Hallman no problem buddy, glad you got it sorted out!
THANK YOU!!!
Thanks so much !! I did a gear swap and the limit switch was maxed out after I tried to adjust it. I took it apart again and thought I broke it. I snapped it back in , followed your video and it works like new !! Thanks again !!
Glad to be of assistance!! 👍🏽
So I followed your instructions. However my issue is my trolley will only move 1 foot forward 1 foot backward. So I moved it to the middle of the rail and it will only go like 1 foot and then returns one foot. I have the limits suggested just like you showed in the video. Any ideas? I did replace my gear and that's when I had this issue arrive. Thanks for any help!
Check to make sure the black notched opto wheel is pressed all the way on the motor shaft.
All-Pro Quality Garage Doors Inc. Freaking genius dude! That is exactly what it was. I took it off and was turning to the shaft with a pair of vise grips to get the trolley where I wanted it. Bingo! Thank you so much man!
Josh Bell can i get a fricken BOOYA or what!!
All-Pro Quality Garage Doors Inc. BOOOOOOOOYA! Thx man.
Josh Bell you got it buddy... we git it done!
this fixed my problem perfectly!
Bingo!!
Thank you, this really helped me out.
James Chorman... excellent! Thanks for watching.
So much bull out there , your video is perfect , thank you for sharing .
No problem James, Thanks for watching buddy!!
awesome video... saved me some cash on a new opener.
Salvo Embers Heck yea buddy!! Save that cash!!!
Thanks, Great informative video~!
New assembly installed no problem .
At what point do you hook the garage door back into the trolley?
as soon as you've made your limit adjustment and backed off the force control dials, then reconnect and test.
