Hi! I have a red light on one sensor and a green on the other. I just added new remotes, they were all working the door. Later on I tried a remote and door won’t open lights are one green and one red. What happened? Everything was working fine.

The issue is these garage door sensors are so outdated in their technology. Take a look at a sensor that can solve the sun issue, alignment issue, coverage issue and also help guide your car in the garage! Let me know if you want to give this a try?

We have a Genie model 3142 that blinks red and ticks and won't open

Bonsoir, Suite à une panne de courant de plus d’un an, et oui j’ai été partie, j’ai refait la programmation. Cela fonctionne bien lorsque je presse les boutons sur le moteur, mais j’ai des problèmes avec mon ouvre porte murale. Le port est usé comme une porte de 10''. Suite à la lecture de la section sur le dépannage, j’ai découvert que le voyant rouge du 'senser' clignote tout le temps et l’autre, qui est vert, reste fixe. Il n’y a aucune obstruction, les 'sensers' sont alignés et aucun autre équipement qui pourrait faire de l’interférence. De plus, il y a une lumière rouge qui clignote sur le moteur. Est-ce qu’il y a quelqu’un qui a une solution ?

Thank you! I placed a box between the two adjacent garage sensors. The sensor blinking stops and the garage door operates normally now.

[@estebancastano8543]

This video helped me thanks a lot. Turn out it was just the sensors not aligned

[@notiprinacional2801]

Je comprendrai

That’s great information. I have a three car garage, all with their own opener. I was having a problem with door no. 1. It had no power going to it at all. I swapped the sensors with a door no. 2 and still no luck. After watching your video, I discovered that there was interference between the 2 doors. I corrected the sensors on door 2 and now everything works. Thanks for the great info. I’ve been searching for a a solution for 2 days and I have a technician coming out tomorrow. Thanks to you, I have corrected the issue, I can cancel there service call, and save some money.

I'm so glad your comment was first. I bought replacement safe-t-beans only to discover they don't work either. After reading your comment and finding a relevant section in the video, I started to play with the second garage door safe-t-beans and lo and behold, broken one started working again. Thank you and the Flannel Guy for pointing me in the right direction (since Genie Troubleshooting guide was useless)

[@scottmccormick2138]

You inspired me to try and swap wires from adjacent working sending unit to troubleshoot mine. It worked! I could not find videos on how these units are wired. Mine has 4 wires going into one side.

[@flannelguydiy6458]

glad it worked for you! please share the video so that youtube will suggest it to more people

[@GoferZeroSix]

Last tip, GENIUS!!! I was wondering why my new opener was operating properly but the stupid light kept blinking.

[@juangalvez8594]

Thanks for posting !!!👌👍

[@itsabearpelt]

I didn’t know the wire orientation mattered. Gonna double check this when I get home. I feel I might just need to replace the entire wire to the unit. It is very brittle.

[@Soldier1287]

It only opens when I hold the button down. Remote won’t work either

[@flannelguydiy6458]

that is a whole separate set of problems. Not related to the sensor/light

[@deadmonkey3003]

It could be that one of the wires for one of the sensors is not connected

[@robertdenton9301]

My green light is solid but the red is completely off….no flash or nothing….ty

[@semperridelis6470]

Great video. Only suggestion is using a level that can be attached to the rope line. They sell small ones with hooks that can be attached to any thin rope line or chalk line.

[@John-bw5yc]

Is it normal to have one red and one green? I remember back in the day both where red

[@flannelguydiy6458]

check the instructions for your model.

[@orionlapalm813]

One of the sensors was not on. Thank you!

[@Cowboysfan2288]

Interference was the winner for me.... thanks

[@bobsokoloski9559]

[@dirkpittthegreat4559]

Thank you. Will give it a try. Hope it works.

[@pavangaridepally5499]

Super it worked

[@kennethfannin8707]

show me close up where the wires go on the motor itself ,, which wire goes where ,,mine has 4 of those plugs ,,, 4 wires but where the heck do they go ,, i bought a used opener and it still doesnt work no matter where i put those wires

[@flannelguydiy6458]

I cannot show you. no way to post a picture here

[@casey5062]

Your last tip worked for me. I switched the sensors around and no issues after that. Thank you!

[@toddlermamaof2]

Thank you!

[@kennethmccain9108]

Great advice, Thank you for solving an issue that had me stumped!

[@larrymack2659]

Interference was my problem… it’s been KILLING ME😮

[@flannelguydiy6458]

thank you for watching

[@flip2113]

Last tip worked! Thank you

thank you for watching. please share the video

[@jimmykarva4328]

Thank you. My garage door opener hasn't worked since my neighbor in our huge condominium complex had his garage door replaced. At first I suspected the garage door company did something to damage my unit. Today I noticed that both sensors are directly next to each other as mentioned in this video. I checked all the other garage doors in the complex and I noticed that the sensors are all on opposite sides of the other garage doors except for the one that was just installed by this company. One would think that a garage door company would know something as basic as this. Perhaps they did and were trying to sucker me for some more business. If that was their intention it almost worked. Thank you again for the advice.
