What part do I need to replace to get the lights to work on a Craftsman garage door opener?


Sounds like a broken or disconnect wire. At least start their. Unplug operator. Take the cover/shroud off, using a bright flash light check all the wires for breaks or disconnects. Repair or reconnect. Also check the bulb screw housing are connect on the back side.

I have a 1/2 HP Whisper Drive. The lights are not working. I have replaced the light bulbs, and I can hear the relay clicking, but the lights do not come on. Other than this, the system operates...


Are you using the newer energy-efficient light bulbs? Most of the problems I have encountered are related to the newer bulbs. Sometimes they just do not make a good connection for some reason. If you are using the older-style bulb, try cleaning the contact points (with the opener unplugged of course), they can sometimes accumulate gunk.

Otherwise, it could be a loose wire- or bad receiver board. Just to make sure, though, definitely try a number of new bulbs to be certain that the bulbs are good.

Also, make sure you check the balance of your garage door, to make sure the springs are properly counter-balancing the weight of the garage door. Otherwise, the opener will work overtime and not last as long. You can see a how-to video on our website.

Craftman Garage Door Opener Quit Working.


It could be a bad logic board especially if you have had any electrical storms in the area. I would remove and check the logic board for burnt or missing traces on the printed circuit board.

Craftman Garaged Door Unit Stopped Working


This sounds like you will have to replace the logic board. Whether you repair or replace get a surge protector 900 joules or higher unless you want it to happen again. You can get replacement parts at searspartsdirect.com. Thanks BB
