Have you checked the house circuit breaker? Do the lights come on? Is the door stuck in the open position?

    You need to loosen the chain enough to take the tension off enough that the motor will run and you can close the door. Now while the door is closed locate the 'up limit' control on the side of the motor unit and turn this control 2 full turns in the opposite direction of the arrow printed on the cover. Tighten the chain.

I have a Craftsman/Chamberlain 1/2 hp 315mhz Garage door opener model 139.1845.DM just stopped working. The motor runs the chain moves, the door doesn't open. Whether I use the remote or pad still n


All garage door openers have a quick release. Have you checked to make sure that is locked in place? Most have a cord hangin from it and you pull it which releases it from the chain. Make sure that is engaged and it should work.

I bought liftmaster 355lm 315MHZ but my garage door openner has only two wires and it doesn,t work


The 355LM was not designed to work with your opener. You will need to purchase the Transformer Model 85 or 95 to make it work.

Garage door motor dead


Keep checking for loose wires. Nothing about changing the gear should cause the motor to stop running. Check the wires on the start capacitor and follow the white wire from the motor and make sure it is connected.
