There are a number of possible causes.

Garage door motor running but chain not moving.

There s something wrong with the garage door opener that s stopping it from opening the door for you. Image taken from a chamberlain manual. If this is the case the motor will run but as the chain isn t where it should be it can t generate the lift to open the door. Home owners say that they can hear the motor running but the opener simply will not operate the door.

One garage door malfunction that is very frustrating is when it will not open. 3 if the chain still doesn t move check the force settings on the motor head. The motor will start and stop in response to button pushes like it is supposed to normally the first push starts it in one direction the 2nd reverses the direction and the 3rd will stop the motor. This process varies by manufacturer and model but many openers can be re engaged by pulling the emergency cord a second time.

I ve not worked on garage doors before but i. If the cord has accidentally or purposely been pulled the automatic door opener will not work until the chain is re engaged. Maybe you have a broken torsion spring or the door is too heavy. When we push the open button the motor runs and makes sound by the chain that opens the door does not move.

Those are the two blue screws. 2 if it is getting power then disconnect the door and then see if the chain will move. The motor should be driving a chain or belt. Automatic garage door opener runs but door doesn t move.

The chain and door connector assembly haven t budged since. If the motor hums but the chain doesn t move that indicates a problem with the motor. As the shoe moves into the trolley the emergency release should reset but if the release is jammed or broken that might not be happening. Press the remote or the wall mounted start switch listen to the motor and watch the movement of the chain.

If the chain or belt moves then the opener motor is ok and the problem is probably at the emergency release. However the chain has completely stopped moving and by extension so has the door.
