Unplug the operator for 2 mins.and remove the wires to the wall control. plug the operator back in if the operator starts running  the logic board is most likely fried (bad) and should be replaced.

Garage door opener


This is cause when there is something blocking one of the sensors. Look on each side of your garage door near the concrete when the door is closed and you will see small sensors that are facing each other.. Make sure they are not misaligned and that nothing is in front of them.

Chamberlain Power Drive 1/2 HP - motor runs but does not move chain


I have the same problem. I just removed the cover and discovered a nylon gear had been worn out. I found lots of shavings inside the cover. The nylon gear is beneath the exterior chain gear. I am looking for information on how to replace it, if I can find the part. If you decide to look at yours, unplug the power and remove the sheet metal screws securing the bottom portion of the cener cover to the front and back covers. Then just remove the upper screws from the center cover. Good luck.
