Replacing capacitor on Overhead Door garage opener after it goes pop!
Вставка

- Garage opener made a big popping sound and then smoke came out. This can't be good, I think to myself.
Turns out, it's not so bad. This is usually the capacitor, a tube shaped gizmo that stores up energy to help start motors.
Found most of what I needed on UA-cam to fix it. But there were a couple points about installing the capacitor that I got from the friendly folks at Overhead Door in Clearwater (thanks Rick!).
Apologies if the video is a bit jerky at points!
My garaged door opener is an Overhead Door Legacy 1/2 h.p. Model 696CD/B but probably the wiring instructions can be applied to any capacitor connection.
When I removed the front (light) panel, I let the light hang by its wires (no need to disconnect). Removed the side cover (over circuit board) to access the screw to the capacitor bracket (leaving circuit board in place), and bottom panel. Had to slide the capacitor bracket off the top panel to get the capacitor out, and found that using needle-nose pliers made removing and replacing the wires on the capacitor easy. The video was a great help. All the screws take 1/4" socket except capacitor bracket, 5/16" socket.
Thanks man! Exact same thing happened to me the other day with the same model. Old vids like this help make repairs way easier.
You bet!!
For anyone wanting to buy their capacitor online, just make sure the "uf" numbers mach exactly and make sure VAC number the same or higher. Up vote this if that was helpful to you. Also for searching purposes they are often called start capacitors. Do not get a run capacitor.
Thank you so much for how to reconnect the wires. Took them off days ago and didn't remember which one went where.
I knew My problem was the capacitor but I appreciate the step-by-step video so I knew what to expect when taking it apart. I did indeed curse the engineer and his entire family for deciding to save a penny or two by not making the wires just an inch or two longer. A tip for anyone reading this, start with the shortest wire first (likely the orange one) when putting the wires back on.
My thanks to Hans. Great advice. My large black capacitor also failed on same Legacy model as you. The local Overhead door gave me a smaller blue Mallory capacitor (shorter), claimed it replaced the longer black one in your video. It was tough getting the old capacitor out from that odd horseshoe shaped slot in the top sheet metal. You saved me a lot of money doing all this myself. it took time to make careful notes of the wiring, and the sequence of removing those plates (that's the biggest pain of all) while standing on the stepladder. Thank you my friend!!
This is great! I am fixing my garage opener this AM and wasn’t sure how to approach the capacitor replacement. Thanks for figuring it all out and teaching us all.
You completely saved my hide... This video was the exact fix that I needed. Thanks for putting this up!!!
Glad to hear it!
Thanks. Appreciate you taking the time to share what you learned.
My pleasure!
Thanks. Followed your instructions and hints. Saved a ton of money!
Glad to hear that. You're very welcome!
Make sure put the covers back on before testing your fix. Without the covers on, the optical sensor inside will cause the opener to stop and reverse randomly.
Could you film a video of it opening and closing with no commentary? Also on those openers the capacitor is know to blow fast on these. Glad you fixed it these will work forever until the door destroys it or it gets replaced. The reason for the short wires is so that it doesn’t get caught in anything. This will definitely help a lot of people. Nice video and job!
Thanks for this video.. I was able to fix my garage!
Great!
Worked for me. Awesome video.
It's an AC Cap, so polarity is of no concern, just keep the 2-YEL
and 2-ORG wires segregated. Also, on mine (2003), the butterfly
wheel is for the board optics. This stupid thing won't run with the
covers off, because of the ambient lighting! Sooo, everything has
to be closed up (no light).
Interesting. Is there some kind of light sensor on it? I don't get why ambient light would even be a factor in a garage door opener.
Great video, thanks for all the help. Just for clarification do both yellows go on the same prong and both orange on the other prong?
Sorry...didn't see this. But I don't remember at this point anyway. I'm sure you could call your garage door co. and ask them if you need to.
At the very end, you can see stains of dried electrolytic from the failed capacitor on the bottom panel.
As soon as I replaced the old capacitor the new one it popped and smoked but first did work and then pop then smoke, then it was dead. Gatehouse Supplies tried to tell me that it wasn't their capacitor that failed. Beware of Gatehouse Supplies, you will not get a refund for faulty merchandise.
Geez! Thanks for the heads up. I got mine from the installer and it's been fine. But good to know re Gatehouse.
Replaced it. It opened closed a few times and is not humming again
Booyah!
Very helpful ty.. another idea would be to take a picture of the wiring..that way you know what wires go where..
Good tip!
@@HansEisenman no worries
What happened when you tried to open it with out the capacitor working? My motor will try to move but just makes a noise
Honestly I don't recall. It's been a while. Still going strong over here.
Hey, Hans, just wondering if your "NGM 18004-B capacitor" is still holding up after 5 years or have you replaced it with another one? I have the exact same model garage door opener and in the past 3 months two aftermarket capacitors (of different brands) have blown, so I am going to order the (Fairbanks Electric)18004-B and hope that it will last for at least 5 years as guaranteed. I do wish for longer wires so that the capacitor could be turned 180-degs in case when it does blow, the fluid would not be sprayed on the control board. It's a design/bean-counter flaw, imo.
Still have the same capacitor but about 5 months ago my son accidentally tapped the door with the car while we were doing some driving lessons. So my door is out of commission until we can afford a new one.
Wouldn't it be easier to just remove the motherboard to replace the capacitor? It look like it's only a few screws to drop it and then put back
I think you'd also have to remove all the wires that screw into the terminals on the board and take out those screws, which probably means labeling them so you don't mix them up. Not a big deal, but it is a bit of work.
Hi. I have the exact same model. Have you ever experienced the door going down 6" then up or the reverse? I seem to hear a click then it will work properly but soon is back to the up and down. Could that click be the capacitor?
Hi Dekal, I have not had that experience. I would contact your local Overhead Door company and ask them. The one here near me was very helpful.
Adjust the force, up or down switch. It shows on the unit.
@@hungton2223 -Tried that many times and doesn't help. Just replaced the capacitor and it's not that.
dekal Might be a board or some type of break in the door. Make sure the door runs freely and smoothly. Make a video of it I will understand it better I fix a lot of these and it can always be different. Hope this helps.
@@jdcalame6714 Without the door attached the chain simply goes down 6" then up about 6". That's it.
My Genie Garage Door opener is completely dead - no lights, nothing.
The AC outlet where the electrical cord plugs in has power.
We did have an Electrical Storm right before I found the Garage Door opener dead.
Do you think it could be the Starter Capacitor ??????
Hope you got it working. Wish I'd seen this earlier, but the capacitor is so inexpensive. Hope you gave it a try.
Did you run to any issues after changing the capacitor out? or is it still working?
Sorry...just saw this. Still working over here! :)
Would you happen to know the female terminal size? Bought the same capacitor but some of my wire terminals corroded. Thanks!
No I don't. Sorry. That's too "inside baseball" for me. I just bought the one there garage door people told me to buy.
Replace the terminal.
I got the same model overhead legacy and also smoke came out one time and it stopped working. Did it work by replacing the capacitor?
Creeper Playz yep!
Yes, it did.
Could you post the contact info for the place you get your new capacitor from? I have an older unit ( 55B ) that I need a capacitor for. Mine is marked 77156-1 (330 VAC , 54-65 MFD) but a manual I found on line has that part number redlined out with a new number of 107871-1 for the capacitor and 108267-1 for the 'sleeve'. I'm on Merritt Island and the local service guy who just showed up said he could no longer get parts for my unit and wanted to sell me a new one for $390. I have to believe there are still capacitors available somewhere.
I just ordered a capacitor for my opener from Amazon.com. Two day shipping $14 total. Search for "garage door opener capacitor" and see if yours is there.
Two days later I received the capacitor from Amazon and about 45 minutes after that the opener was back working just fine! $14 versus $400 for a new opener.
Which country use 330 VAC? In general, we use 220 VAC. What model do you have Genie or others?
Hans. Hats off to ya! 🎉🎉🎉
getting dizzy
You should take a picture before you pull it off.
This is really a broken English...why not complete a sentence before going to another?
