    My garage door opener stopped working. Neither the remote nor the wall button works, no lights come on and there is no noise. It, too, acts as if there is no power. Any ideas?

Upon closer inspection I found that the power board had burnt. Weve had several power surges after the ice storm and apparently one weakend the unit. Price for the board (from craftsman) is like 80.00 and not knowing what else may have took a hit I replaced whole unit for 140.00.

Chamberlain troubleshooting


The problem is with the infrared sensor cameras! You must check to see that both cameras have their led lights lit, if not you can position the one that does not have its light on which is called the receiver , The receiver receives a signal from the sending infrared camera and if it is not positioned correctly it will not receive a signal forcing you to hold down the wall station button . The reason for this is a built in security feature letting you know the sensors are not aimed at each other properly ,once you have an indicator light on both sides your opener should work fine and you wont have to stand their holding the button until the door closes ...Hope this helps you , good luck Glenn

If the main light is flashing 10 times when the door reverses it is a door sensor problem. Make sure the sensors are pointed at one another and the small light on each one is lit and not flickering. Tweak them if necessary. If you cannot get both lights to come on you have bad sensors.

Learn light is blinking in a serise of 4 times.


The light is sending the code for:

Safety reversing sensors slightly misaligned (dim or flashing LED).


Tweak the sensors to make sure they are pointed at one another and both lights are lit and not flickering. If your opener is working okay then you may just need to unplug it for about 5 minutes and it should reset so the blinking light quits.

My keyless opener is 4 years old. the pad and remote will nor open door. Only the button inside of garage functions. WHY?


If they will only raise the door then the problem may be in the safety sensors. Make sure they are aligned and the led light on them are lit. If they will only lower the door then you may have the vacation lock engaged. On the wall button press and hold the lock button for 2 seconds and then try. If they just do not work at all then replace the logic board. Thanks BB

Remotes don't work, keyless entry won't work, wall remote some


Check to make sure the door sensors are pointed at one another and the small light on each one is lit and not flickering. If you cannot get both lights to come on then your sensors have failed.

Chamberlain Liftmaster GDO just clicks, no lights no open/close


Pull the logic board and check it for burnt or missing traces on the printed circuit. Thunderstorms love logic boards.

Craftsman # 139.53879 -1/2 h.p. Door opener- problem re-programing remote unit. Garage door will open but not close using remote. Wall switch works fine to open & close.


Check your door sensors. They must be pointed directly at one another and the small light on each one must be lit and not flickering. If by tweaking them you can't get both lights to come on you may have a wiring problem or one of the sensors has quit working.

Craftsman Garage Opener Clicks only and LED blinking 5 times


Just fixed this problem tonight. Had the 5 blink/flash thing. Opened it up and saw that the motor wasn't spinning so it wasn't a bad rpm sensor. Jumped the red to black and then the blue to black to verify motor worked. At that point assumed it was the logic board not telling the motor to start, but I could hear the click of the relay. Pulled the logic board out and noticed a solder joint that had failed directly behind one of the relays. Resoldered that joint and the garage door opener worked again like a dream. Hope that helps someone else.
