Craftsman Garage Door Opener

texashondaFebruary 1, 2010

My door opener went completely dead and would not supply power to the lights. I check outlet for power and had 120V. I thought the logic board was fried, so I bought a used motor module off ebay (cheaper than a replacement logic board). I removed defective unit and replaced w/ used unit w/o problems. Unit now works fine.

I decided to check my removed motor module by plugging into power and shorting the manual switch to see what would happen. It came on (LED flashed code 1) and when switch was shorted ran a few seconds and went off. Motor stuttered and LED flashed code 4 when I shorted again to see if motor would reverse.

Is it possible, the logic board is OK? Can I test the logic board w/o the saftey sensors attached to logic board? I will keep removed motor module for spare parts, but I have sneaky suspicion that it's OK.

You can't test the logic board beyond what you are doing without the sensors attached. I would pull the logic board and check for burnt or missing traces on the printed circuit especially around the small transformer. The connections to the transformer sometimes come loose.
