ATTENTION: You still have to wire the sensors backwards from what he explains in the video to get them to work. Black to White on both sides not black to black and white to white as he explains. If you do not do this the sensors will not work properly. I spent way to long on this before scrolling through the comments. Hopefully by posting this again it will appear at the top of the comment section.
Just installed my sensors. Michelle is absolutely correct. I attached the white wire with the white wire and white/black with white/black as per instructions. It did NOT work. Crossed them like MM stated here and it worked. THX MM.
Just changed out my sensors and had to cross the wires. I guess the wiring was different 11 years ago. Also, the wire connectors he used in the video didn't work for me. I read online that that type of connector only works with multi strand wires. The sensors I got were single strand, so I just ended up twisting and taping.
I have moved in to a new place 2 days ago suddenly my garage opener stopped working I did not want to call the landlord after 2 days moving in to a new place and guess what your video saved me and I feel so great I did something by myself Thanks a lot
I followed your instructions and replaced my garage door sensors. The sensors I bought come with the wire connector in your video. Now it's working great!
Thanks for the easy-to-follow instructions. Your efforts to help do-it-yourselfers like myself saves us money and increases our confidence in future endeavors. Everything is working properly now!
Thank you I was getting aggravated. I was trying to put the sending where the receiving was in the receiving where the sending wasn't couldn't figure out why they wouldn't work! Lol you just saved me time and money!
Worked! I didn't even have to use the supplied new mounting brackets. Also, the 2-wire silicon splice connectors come with the replacement kit. Both Lowe's and Home Depot carry these kits. You just have to make sure this generic replacement kit (Chamberlain - Model # 801CB) matches your door's sensor description.
FYI according to this video (ua-cam.com/video/c854VnEjHaA/v-deo.html) the connectors are called jelly crimp connectors and you don't have to strip the wires before inserting them.
I did the replacement, but part of the garage door is rubbing against the back part of the clips. It looks like as the garage door goes down, it shifts slightly and the bolt that holds the cable at the bottom of the door rubs against the 2 flat parts of the clips. The original mount was using one screw to hold the bracket to the rail. I can't mount it to the wall because the clip is not long enough. I have it temporarily on top of a can near the door. Any thoughts?
I had to install the wires on this backwards. When I did black to black and white to white the light did not turn on. When I reversed the wires the lights turned on and everything worked.
great video. please tell me the exact name of the crimp connectors u used. i tried looking them up and didnt find any that look exactly like yours. where did u get them? a home depot type source - or electrical supply??
Nice video! I had a couple of questions. Does it matter which side the sender and receiver are on? Also, does the wire w/ the stripe get connected to the positive or negative terminal on the controller? Thanks in advance for your help!
8 Wires & 4 Wires. I have 8 wires, 4 wires on each side. Directions twist solid color wires together Twist stripe color wires together That makes 2 twisted wires on each side. Connected 2twisted wires to top screw and two twisted wires to bottom screw. Test When wired right Geen LED is on (not blinking) and Red LED is on (not blinking) when sensors are alighted. Sensors are not aligned Red LED blinks Wires 8 or 4 wiring.
Question. How do you know which wire is the black and the white? They looked the same to me. Pleasee if someone could help. Im having to fox mine this weekend. Thank you in advance!
Attention you have to wire theses sensors just backwards from what he is tell you here you notice he did show you them working theses sensors are cheap but will work but you sure do have to wire them back ass to.
1. It would have been more helpful if the installer showed the 2 sender / receiver sensors and green and amber lights for noobs like me. 2. There seems to be some commenters who said that the wiring of white to white and black to black has to be reversed. This seems to be a detail that an experienced installer would know right ? Can it be that the wiring of the wires was reversed back at the garage door opener itself ? Thanks
I had someone come and wanted to charge me $195. I said I'd check around. I guess he wanted to make $150. He said the sensors cost $150 and he wouldn't do it for $50. He must of really thought I was out of touch with the price of things.
I can't able to close my garage door, I check the sensors and it seem like find.The green and red light is not blinking but still the door won't close. The Motor seen to be ok.. should i replace the sensors ?
The video did not say anything about lining up the sensors! Always, one is green and the other is yellow. Yellow is the sending the green is receiver. It doesn't matter which side you put either color. If the sending has power, the yellow light stays on sending the signal to the green receiver. If the green receiver is not on or blinks, it's not lined up. When the green light stays on, it's lined up a working. The video fails at not saying anything about this.
If you want to switch the side of the sensor do you have to switch the end wiring to the control box? I need to do this in order to fix the sunlight blocking issue.
I've never done wiring but I'm going to attempt to replace the sending eye (ordered from Amazon, hasn't arrived yet). So, stupid question... do I need to turn off the breaker switch to the garage door before I do this?
@@Cptkarma6 Thanks. Mission accomplished about a week ago. The instructions that came with the eye said to unplug it. (Something told me to cut the power source before cutting the wire). It was a very good feeling to fix it myself as well as saving a ton of $. The garage door people wanted $99 just to come out and check it out!
Nice video Json: I'm trying to find out if my Lift-Master sensors are water tight? My garage got 2 feet of water from Irma.. Message on Keypad says "Sensor Malfuntion" . Anybody know if these senors are water tight... if not I buy a pair for $30 on Amazon
Will new sensors get rid of the problem with sunshine screwing them up and not shutting? I haven't always had the problem with the sun screwing up the shutting of the door. I just changed out my sensors and I'm getting no light up on either of the sensors. How does that wire get connected within that silicone crimp case? I crimped them, both whites in one and both blacks in one. There's no juice getting into the new sensors.
Little late but just find out about the video :) 3M Scotchlok IDC Butt Connector amazon link: www.amazon.com/3M-Scotchlok-Butt-Connector-Pack/dp/B0076AY1PC/ref=pd_bxgy_469_2?_encoding=UTF8&pd_rd_i=B0076AY1PC&pd_rd_r=1ZNBBAMWGPH07P1XZ9KE&pd_rd_w=Mnu88&pd_rd_wg=yLBZi&psc=1&refRID=1ZNBBAMWGPH07P1XZ9KE&dpID=5171OXIyyML&preST=_SX342_QL70_&dpSrc=detail
neither one of my sensors is coming on and the garage wont close unless i override the sensors. buying new ones to replace them and this doesnt look hard to do. save me some cash!
@Maria Rafanelli I know this is almost a year late but try these connectors: www.allelectronics.com/make-a-store/item/CON-023/2-WIRE-TELECOM-SPLICE-30/PKG/1.html They're called 3M Scotchlok.
I started with a non-functional door - no up, no down. Replaced both sensors. Now door goes up easily, but I must press and hold button to go down. If I just press, the main unit just clicks - indicating a broken sensor or broken beam path. What should I do? stu@shearwater-sailing.com

Is that why my sensors lights did not work and the garage kept opening but not closing?
Thanks for adding this important piece of information. Your correct it's NOT like rewiring a lamp etc in your home.

Who’s watching this in November of 2023!! This guy!! Lol thanks made that look super easy
So proud of myself (and you essortment)... fixed my garage door (got flooded and developed junk in the eye) this morning. Thank you!
I just used this video to replace the sensors on my garage door, and it's working again! Thanks so much.
This was very helpful. Save me $130. I did it myself. Didn't think I could but got the job done. Bought the kit from home depot 39.98.
Same!
did you reset anything at the motor box afterward?
Thanks for the easy-to-follow instructions. Your efforts to help do-it-yourselfers like myself saves us money and increases our confidence in future endeavors. Everything is working properly now!
Thank you I was getting aggravated. I was trying to put the sending where the receiving was in the receiving where the sending wasn't couldn't figure out why they wouldn't work! Lol you just saved me time and money!
I needed some tips to pigtail the sensors, I'm glad I found a video for it!
Thank you SO MUCH! I followed the steps in your video and replaced the sensors quickly and it works great now!
Great instructions! Easy replacement! Thanks, Jake!
Perfect tutorial, told me everything I needed to do and was extremely easy to follow. Thank you for posting this.
Do we have to strip the wires if we use that crimp on? Looks like you just stuck it in there without stripping it. Thanks
Worked! I didn't even have to use the supplied new mounting brackets. Also, the 2-wire silicon splice connectors come with the replacement kit.
Both Lowe's and Home Depot carry these kits. You just have to make sure this generic replacement kit (Chamberlain - Model # 801CB) matches your door's sensor description.
so you get it wired back together... and still no red/amber light... what then?
Same question no lights
Great video, answered my questions on the crimp connectors supplied with my new sensors. Thank you.
sally majors do I strip the wires
Angelo Laliotis I have the same question, do we still have to strip the wires if we use that crimp on?
Awesome video. Your demonstration was Simple and to the point!
Thanks..
FYI according to this video (ua-cam.com/video/c854VnEjHaA/v-deo.html) the connectors are called jelly crimp connectors and you don't have to strip the wires before inserting them.
Thanks for the video! Question - Do you need to strip the wires first before putting them inside the little silicon crimp connector? Thanks
Very helpful! Thank you so much!
I did the replacement, but part of the garage door is rubbing against the back part of the clips. It looks like as the garage door goes down, it shifts slightly and the bolt that holds the cable at the bottom of the door rubs against the 2 flat parts of the clips.

I wish I found this video 10 minutes earlier. Just wasted $90 for a sensor replacement
I had to install the wires on this backwards. When I did black to black and white to white the light did not turn on. When I reversed the wires the lights turned on and everything worked.
One of the
sensor has green light and second one is yellow. Is it should be so? Which of them sender and which receiver?
Do you not have to trim the wire ends?? And how do you make sure the sensors are aligned?
How do I tell which sensor is the sending one,and receiving?
great video. please tell me the exact name of the crimp connectors u used. i tried looking them up and didnt find any that look exactly like yours. where did u get them? a home depot type source - or electrical supply??

No a word about adjustment? Sending and receiving sensors have to align.
Can the older sensors be replaced with the newer smaller sensors ???????
I can't able to close my garage door, I check the sensors and it seem like find.The green and red light is not blinking but still the door won't close. The Motor seen to be ok.. should i replace the sensors ?

Not a stupid question... you should be fine just unplugging the opener before you splice the new unit. Good luck ~ it really is simple ✌🏼

you have to hook the wires up backwards for these cheap sensors to work believe me try it and see.
My sensor one has two wire and one has four wire. so how I replace it with lifemaster Safety Sensors 41A5034?
Thank you so much for posting the video. Which brand/type of silicone gel crimp connector would you recommend for a garage door?
Little late but just find out about the video :) 3M Scotchlok IDC Butt Connector amazon link: www.amazon.com/3M-Scotchlok-Butt-Connector-Pack/dp/B0076AY1PC/ref=pd_bxgy_469_2?_encoding=UTF8&pd_rd_i=B0076AY1PC&pd_rd_r=1ZNBBAMWGPH07P1XZ9KE&pd_rd_w=Mnu88&pd_rd_wg=yLBZi&psc=1&refRID=1ZNBBAMWGPH07P1XZ9KE&dpID=5171OXIyyML&preST=_SX342_QL70_&dpSrc=detail
Which brand?
Are garage door sensors proprietary, I mean, will a Chamberlain brand sensors work with an installed Genie garage door opener?
genie won't work with Chamberlain but you can put linear photo light on it. I wouldn't do that because linear is trash.
i got no space beside the track what should i do?
You can mount them on the floor.
neither one of my sensors is coming on and the garage wont close unless i override the sensors. buying new ones to replace them and this doesnt look hard to do. save me some cash!
Did that fix your problem? I have the same issue and I can't figure out if it's the wires or the sensor

By the way, neither light works on either sensor??????
DO NOT BUY! Stopped working right after the warranty expired and the company refused to do anything about it.
You installed them backwards. Green eyes should not face to wall. They should face interior of the garage so they can be seen.
