Liftmaster Professional 1/2 HP Door Opener Stuck

techdesignerMarch 6, 2007

I pressed the button to activate the Liftmaster Professional 1/2 HP garage Door Opener and it makes a click and starts the motor then stops. I thought the door was stuck so I unhooked the chain and tried the button again and the gear turns 1/8 inch and stops. There is no safety electric eye 6in from the floor. I did find a small gray push button I assume is a reset and tried unplugging to reset. Anyone have any ideas on replacing parts or do I just have to repace the door opener?

Take the cover off and check the drive gear. It is white nylon just in front of the motor. You may find it is stripped.
