I agree with the last comment. I played around with the sensor light that was yellow to no change. It’s cleaner now than I’ve ever seen it but my problem was something to do with the remote. I gently cleaned off the inside of the remote, and then it started working again. One of the sensor lights remained yellow as it started to work again.

This really helped. I didn’t know what was wrong with my garage door until I watched this video. I had a broom blocking the sensor 😂
Thank you for this video!

This entire video should be taken down and rewritten. He is completely off the mark about this applying to all brands and as far as a yellow light being a problem. My Chamberlain emitter is NORMALLY yellow and receiver is NORMALLY green. A yellow indicator is NOT an issue and has people needlessly changing door sensors in a effort to get rid of a yellow indicator!

Great video. I was able to get my garage door back working! Thank you 🙏🏾

It seems the loose wiring might be the trick with mine, although I did need to clean the light sensor. Thanks!
The door is closed now someone else will need to troubleshoot any further problems. 😅 ...I wish!

Thanks for your help!

It worked!! Thank you so much for your video!

Thank you for sharing this information ! It really helped. My sensors weren’t aligned properly

[twisteetreatofi-drive]

Thank you so Much!! Your video really helped. I was able to fix the garage door issue in a minute upon watching it.🙏

Mine are mounted 3 inches apart on TOP of the garage door mechanism. They are aimed directly at each other, 3 inches apart. There's no way they can be out of alignment. I'll check the wires this weekend. I have lots of possums and raccoons in my garage, in the rafters. they have parties up there.

No no no! A yellow light on one side is correct and normal. One side will be green the other yellow or red depending on brand. A yellow light does NOT mean malfunction or miss alignment. A blinking light means alignment issue or wiring issue. Aligning the sensors will not change the light's color please correct your info!

YOU JUST SAVE ME SOME MONEY THANK YOU YOUR VIDEO IS THE BEST I GOT ON THIS YEAR😊

[rogermoore]

Good advice. My track was loose and flexed which caused my sensors to misalign at the half way point and the door to go back up.

[debbiecollier]

Thank you for this information I was able to fix. You Rock 💪👍

[judywilner]

Question, about 6 months ago I had a motion light installed outside of my garage, 2 times in the past month I woke up in the middle of the night the light was on, and the garage door was open. I close the door and the motion light outside the door goes out. The light is mounted above the garage door on center, outside. Can the motion light somehow trigger the garage door to open??

[watchembleed]

also, check the bottom of your garage door as it's going down. I had a leaf caught in a cobweb that kept triggering my sensor 😅

so my sensors are okay, but suddenly, the craftsman garage door opener stopped operating, and the yellow led is slowly blinking, why suggestions? It seems like the control unit that is attached to the wall is not responding, for some reason. Only lights get turned on when you cross the sensor path.
