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

1 Answer

Door closing all but an inch then pulling back up

When we close our garage door, the door will go down about half way then it will go back up.  It will not close unless we push on it to get it to go all the way down.  We have a 1/2 horsepower craftsman opener that should have the power to close the door.  Does anyone know what is causing this?   Mine is doing the same thing, about an inch or two short of complete closure, and no matter how much I futz with the sensors, it doesn't seem to solve the problem (and mine don't have lights, either).

    I'm confused. You say your door goes half way down and reverses and then you say it goes to 1/2 inch of the floor and reverses. Are you posting the problems for 2 doors?

You can hold the smart/learn button in for 6 seconds and this erases the memory of the logic board. Then you must program your remotes and keypad.

I have liftmaster door opener 41a5021-1d. Using the remote door closes only half way. how can I repair this problem?


When the motor stops in the down position, pull the emergency release handle. Push the door fully closed by hand then engage the emergency handle. Open the door with the remote and then close it with the remote to make sure the door closes completely.

Linear garage door opens and closes when close to unit about 10 '


when the door stops moving when going down, pull the emergency release handle on the door and then push the door closed by hand. Once it's closed push the emergency handle back so it engages the chain. Open the door and close it a few times to make sure it closes all the way with the motor.

Garage door opens about 4 inches, stops, then goes back down. No flashing lights at all. One sensor light is green, the other is a steady yellow. What's the issue?


something may be obstructing the door, so pull the red emergency release handle and try to pull the door manually.if you cant move it manually, call for professional help

make sure all snow and debris are clear of the area where the door closes

if there are no obstructions, manually set the adjustment controls on the back side of the opener panel. weather can sometimes change the amount of force needed to open/close. adjust the setting with a screwdriver to no more than 260 degrees, about 3/4 of a turn

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.

I just installed a sears craftsman 1/2 hp garage door opener. when i close the garage door with the remote the chain track bends up just about 12 inches before it closes all the way, and this only happens...


What is wrong is you need to adjust the limit on the door when it comes up. What it is doing is coming to far back on the track. You need to push the back limit forward away from the motor so the door does not come back and drop down on the inside of the garage. The opener is trying to push the door up hill to get it to close that is why you are getting the bend in the track.


Good Luck

Have to hold the push button inside my garage to close garage.


You have a door sensor problem. Make sure the sensors are pointed at one another and the small light on each one is lit and not blinking. Also check the wiring.

Door closing half way then pulling back up


Check your door sensors. Most likely one has been bumped and they are not pointed at one another. Tweak them until the small light on each one is lit steady and not blinking.

Open and closing problems w/ garage door


First adjust the down limit setting. There is two white screws on the side of the opener. The one that says down needs to be turned to the less side. One full revolution of screw adjusts approx. two inches. Turn it down until the door does not close all of the way and the slightly turn it up until the door closes all of the way with stight pressure on the door. Next there are two blue screws on the back of the opener. they should be on the five setting on both the up and down screws.
