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

1 Answer

Garage door will open to sensor level and stop

I went to open the garage door and it would only open about 4 inches from the ground. If I push the button again it goes down, but then pops back up to the 4 inches. Help we are new homeowners and do not have anyone to ask. The garage door is a liftmaster.

You might have a broken spring. Check on the a the header above the door there should be a tude with a drum on each end and 2 springs (maybe one) towards the center. se if one of the springs has a gap (1-2 inches) in it. If it does you will nedd to cal a door company in your area. I recommend you replace both springs.
If you need to get you cars out some times you can help the operator to lift the door by lifting the door while the operator is lifting the door. Be very careful not to get your fingers in a pinch point and be sure to lower the door the same way.

Garage door only raises about two inches then stops.


Check the door springs and also remove the cover from the motor unit and check the drive gear. The door spring could be broken or the drive gear may be stripped.

The sensors only work when the door is closing.

Most likely your door sensors are out of alignment. Make sure they are pointed directly at one another.

My craftsman 1/2 hp garage door starts to close and then opens up


I had a simular issue, except mine was that the previous owner decided to mess with all the settings and mounts and screwed everything up.

The problem isn't your force sensors its your downwards stopping sensor on the opposite side of the opener. For me I had to take the entire panel off and replace the sensor back in its holder, but try adjusting that sensor setting (clockwise goes down, counterclockwise goes up).

If that doesn't work then i dunno:)

Also set both force settings in between 0-1, for some reason with mine if i set it higher it would set them off....

Garage door won't close.


After replacing the worm gear and main drive gear on my Craftsman 1/2 HP garage door opener I found that my door moved about 4 inches stopped and reversed the same distance. I checked all the settings and everything seems OK. What fixed the problem was I released the two allen set screws on the end of the motor shaft and pulled tha motor shaft toward me. When I replaced the black plastic cap that looks like a pill cap top on the end of the shaft this corrected the depth setting that cap rotated through the RPM sensor. I set the limit settings (up and down) on the side of the opener and reset the force pots marked (KC) to mid range.
the door now works. I hope this helps. I also checked and eliminated the door sensors by putting a box in the beem this inhibited any movemnet at all, so I knew it wasn't the door sensors as there was at least 4 incheds of movement prior to the box and nothing with the box.

Door opens only 6 inches and stuck


I would try jumping a wire across the white & red terminal to see if your safety sensors are working Properly! If your door opens you have a loose connection or faulty sensors.
