Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+

1 Answer

Garage door close but motor keeps running

I replaced the drive belt on my garage door opener because the other one broke. My garage door works fine in the opening position. It open to the position where it should, stops and the motor shut off. The problem lies during the closing cycle. The door cycle closes but the motor keeps running. It's seem like the motor wants to close the door even further but the door is already down. As of now my opener is unplugged otherwise the motor will keep running and my chain drive is rattling like crazy.

This all happen a day ago. Not knowing what the problem were so I was messing with my remote to try to get the door to work. Maybe this what caused the belt to snap because of the tension on the drive and door.

The close setting limit switch needs adjusted. Once it is adjusted it should work just fine.

I installed the belt of the lift master garage door opener, but it looks like it has a lock and it does not open and close correctly. How can I re-set it?


The position of the belt and the limit assembly must be synchronized to operate properly. You need to loosen the belt enough to lift it from the pulley on top of the motor and then run the motor until it runs in the clockwise direction and stops. Now with the belt connected to the door and the door closed put the belt back on the pulley and tighten. Should do it.

The motor runs but it only opens a few inches and slowly goes back down its a chamberlain whisper drive model HD900D


Hi. I have seen this before, although usually not from chamberlain garage door openers.

Pull the release cord that unlocks the door from the opener, and manually open the door ALL the way open.

Then lock back in place in the open position.

Then use automatic opener to shut door.

It will close very slowly, but should close all the way.

Then, open the door again using the remote, and the door will once again open slowly, this time it should open all the way.

Then close door with remote, and door should now close as it is supposed, with the proper speed.

The slow opening and shutting is the system position sensor resetting itself.

This is why your door is acting up.

I would also look up by the belt drive connects to the front of the garage door opening, to make sure there isn't any dirt, cobwebs, or other obstructions on the sensor that may cause it to re-close the way it does.

My plastic gear stripped soon after a spring broke. I think the broken spring put a huge load on the opener that day and ruined the gear. Replacement wasn't too hard. It will be obvious when you remove the cover if the gear is stripped. Here are instructions:

You have either a broken door spring or the drive gear in the motor unit is bad. The drive gear is a white nylon gear just in front of the motor and it will be obvious if it is bad.

Remove the cover from the motor unit and check the drive gear. It is a white nylon gear just in front of the motor. Also check the door springs. One of them could be broken.

Hi there. I have a Chamberlain Whisper Drive


I just had that problem this morning and the cause was that the springs that help hold the weight of the garage door were broken. This caused the garage door opener to raise the garage door a fe inches and then drop again. We called in a professional and $200 later we had new springs and everything works fine now.

Chamberline 1/2 hp belt drive opener that stops opening


It sure sounds like a broken spring. Sometimes the break can be difficult to see. How heavy is the door to lift manually. This will give you a good idea.

BE SURE YOU HAVE THE CHAIN/BELT INSTALLED PROPERLY.
IF THE DRIVE IS AT OR NEAR THE UP LIMIT SWITCH THE DOOR CAN'T GO UP.
LOOSEN & REMOVE THE CHAIN/BELT.
TRY RUNNING THE OPENER TO BOTH LIMITS - JUST TO SEE IF IT WORKS.
RUN THE OPENER TO THE DOWN LIMIT.
MOVE THE TROLLEY TO THE CLOSED POSITION - RECONNECT CHAIN/BELT.
HOPE THIS HELPS
