My father in law has a Chamberlain model 3245 garage door opener. All of a sudden it stopped working. No power at opener on wall and the reset button on side of motor panel didn't do anything.
The sensors lights on the floor by door work as one light is green and the other is yellow.
The gear teeth look good and the canister doesn't look swollen or damaged in any way. Any idea what it could be?
