Door will not open with or without motor

Pull down on the manual release rope. It may be hard to pull.

It is not fixable without access to the motor unit. There is a way to open the door but it involves drilling a hold and using a long tool to reach the manual release. A door opener technician can do this job.

If you try to close, do light bulbs on motor blink. If yes, problem is eye. Clean, alighn better or change. If not , try a little more down force

You will need to release the door from the opener and then open the door manually and make a mark on the t-rail where the trolley is. Then remove the t-rail from the motor unit and manually run the rack to the mark on the t-rail. Now run the motor until it runs and stops in the up position. Reassemble all the pieces. This will get everything back into sync.

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.

My guess is that you have a broken spring. Look at the springs and see if you can see a gap in one of them. If you pull the release and you can't open the door without struggling then you definately have something wrong. The opener is trying to heft weight that it is not designed for and is stopping itself to prevent damage.

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.

Unplug the unit and remove the cover, usually eight screws, if you see a lot of white dust in the cover check the nylon drive/worm gear, they will need to be replaced.

with the door down, disconnect with the emergency release, see if the motor operates
with no load...if the the track moves you probably have something obstructing the door
ie; a broken spring, door locks, etc ... the chain should be adjusted for just a little
**** mid way down the rail (1/4") if it still doesn't move ... call sears.

Thats one of the symptoms of a lightning strike or a power surge. Without actually being there I would suggest replacing the back-board. But as with lightning strikes and power surges sometimes other electronic components could have been damaged as well.
