we recently bought a new house. The garage door opener is not working. There is power, and the switch on the wall is good. The light stays on all the time, it never goes off. When you push the switch to open the door, the opener does not even try to move. Not so much as a "hum" or a "click". Does this mean the motor is bad? I've tried and looked at everything I know to try and look at. Does anyone have any ideas as to what the problem might be?
