Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+

1 Answer

I have a Craftsman 1/2 HP garage door opener (10yr). A week ago I tried to open the door and it moved about 1 foot and then closed again. Since then does the same thing everytime. I disconnected the door and tried; same results - the chain moves about 1 foot and then reverses to the start. Nothing is blocking the chain, its not damaged.

Remove the cover from the motor unit and check the drive gear. It may be stripped.

Remove the cover and check the drive gear. It is white nylon and is just in front of the motor. It may be stripped. Take a close look at those door springs. They can sometime appear to be okay when one is broken.
