Garage door opener just hums, won't go up or down

Either the motor has seized or the door itself has jammed. Unlock the manual release (Usually a cord or lever hanging down 1/2 way along the track) Sometimes if its a side mounted motor, the lever will be at the side of the motor .Pull the cord or move the lever, and the door should be able to be opened manually. If its stuck then you will need to check the tracks and rollers on the door and door frames to see whats jamming it. Repair or replace as required. If the door comes up freely, that will prove its not the door jamming.Try leaving the door in the manual position and turn the motor on. The door wont open or close itself when in the manual position, but the motor should run. If it still hums, I would say the motor has seized. Sometimes, its cheaper to get a new opener / motor complete assembly rather than a replacement motor on its own. Check with the manufacturer and or supplier of the door opener to confirm.

M otor hums but door does not open

If the motor is running and the chain or belt isn't moving, you have a broken gear in the opener.

Door will not move up or down,the drive motor just hums.

On the inside of the motor box, check to make sure the chain has not come off the gear.

Motor hums but door doesn't move. If I disconnect door and give chain a horizontal poke, it will move. When I reconnect door it returns to humming, without movement.

Remove the cover from the motor unit and you will find the drive gear has stripped. White sawdust all over. The part number for the gear kit is 41A2817 and it comes with instructions. It is available at any good door opener service company.

Liftmaster door opener, motor hums but chain and door does not move. Any ideas? Thanks

If the motor is running but the chain isn't moving you have a stripped drive gear. Remove the cover from the motor unit and check. It should be obvious.

Garage Door opened but will not close. I opened

I think the trolley has jammed against the bolt just in front of the motor unit. Remove the bolt and then run the door until it is closed. With the door closed locate the 'up limit' control on the side of the motor unit. Turn this 2 turns in the opposite direction of the arrow printed on the cover. Replace the bolt.

Garage door will not open or close

Hello, You should have a cord in the middle if the track up high to release the door from the motor bracket. i would release it and confirm that the door will raise and lower with you pushing it. Then if the door feels free I would lower the door manual and go over the the inside button and press it to see if the motor will run without the pressure of the door. This will at least pinpoint where your problem is. The door itself could just be in a bind within the tracks so by releasing it from the motor that might free it up.

I hope this helps you and have a great weekend.
