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

1 Answer

Door closing half way 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?

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.

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.

My garage door will only open half way. It appears to be getting stuck when it is opening.


If you haven't gotten your issue fixed yet... I had the same problem (stopped opening half way when using the remote, went down fine, could lift/close manually fine as well) and this happened on our first cold weather day of the year which was very telling. Anyhow, there are two gauges/dials on your garage door opener unit itself (above, where the light is) which controls how much torque/strength your door uses to open or shut through resistance. I turned mine up some and it now works fine; what likely happened was that the metal tracks or the wood frame condensed in the cold and was providing just enough resistance to stop it when opening - as they have a security device built in to stop if they meet any resistance. Hopefully this helps!

Broken sprocket coupler


Could be. Yet you may only need to adjust the springs and not replace them.. In case you have roll up/ sectional garage door, it should be quite easy you need to release the traveler from the rail so you can open and close the door manually/by hand then, while open the door on the knee level leave the door. If it falls down the springs need adjustment.
In general the door should stay at the same position on every stage it is while pulling it up and down.
If the door falls/ closes down not enough tension on springs, if door opens up too much tension on springs. If door acts funny.like close when close to the floor and jump up when its futher more open, it means that you don't have the matching springs for the weight of your garage.

Overhead door opener 555 with manual release won't lockup chain


Sometimes if the clip is not reset then it wont catch the chain mechanism again to open or close the door. If you havent already reset the pull cord clip then that would be my guess. Try closing the garage door reset the clip with the rope attached, push it up til it clicks. and hit the garage door opener button. the rope and clip should move along the track until it hits the arm bracket where the garage door attaches to the chain mechanism.

If that does not do the trick then the clip has some screws on either side of the plastic casing and may need to be loosened and readjusted to match up with the garage door arm bracket and then locked back into place. That should do the trick if all esle fails, you may have to call the door company to come and correct the problem. Hope it works out!

How to switch back to automatic after manually close the garage d


mikey-moore's advice helped me figure out what to do but it's not exactly what I had to do. Manually open the garage door all the way. Then hit the automatic button you normally would use to open and close your garage door. The bracket slides back and locks into place. Hit the automatic button again and the garage door should automatically close.

Door closing all but an inch then pulling back up


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.
