Garage Door Motor Running But Chain Not Moving

Automatic garage door opener runs but door doesn t move.

Garage door motor running but chain not moving. The motor will run but will not move the chain. In most cases the cause will be a stripped gear or a chain that has come off the sprocket. 3 if the chain still doesn t move check the force settings on the motor head. There are a number of possible causes.

Those are the two blue screws. 2 if it is getting power then disconnect the door and then see if the chain will move. Image taken from a chamberlain manual. Press the remote or the wall mounted start switch listen to the motor and watch the movement of the chain.

When we push the open button the motor runs and makes sound by the chain that opens the door does not move. 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. If the cord has accidentally or purposely been pulled the automatic door opener will not work until the chain is re engaged. 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.

One garage door malfunction that is very frustrating is when it will not open. 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. If the chain or belt moves then the opener motor is ok and the problem is probably at the emergency release. Home owners say that they can hear the motor running but the opener simply will not operate the door.

Maybe you have a broken torsion spring or the door is too heavy. This causes the motor to run for an extensive period of time before it seems to timeout and give up. The motor should be driving a chain or belt. However the chain has completely stopped moving and by extension so has the door.

I ve not worked on garage doors before but i. This process varies by manufacturer and model but many openers can be re engaged by pulling the emergency cord a second time.
