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

1 Answer

Arm won't move

When the button is pressed the opener clicks twice but does nothing. Also there is a green light on the opener that blinks four times that I have never noticed before and was wondering if this was the indicator of what was wrong but I do not have the manual to research this.

I am trying to reprogram the keyless entry for the garage. The garage door is a Lift-Master model 1280


If you know the existing pin you do this:

  1. Press the four buttons for the present PIN, then press and hold the # button. The opener light will blink twice. Release the # button.



  1. Press the new 4-digit PIN you have chosen, then press ENTER. The motor unit lights will blink once when the PIN has been learned.


Test by pressing the new PIN then press ENTER. The door should move.


Otherwise you do this:



Locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and immediately release this and then walk over to the keypad and key in any 4 digit code you like and press enter.

When our garage door opens, my light turns off immediately. How do I get it to stay on for about 5 minutes?


Try this:

Press and hold the Lock button until the light blinks (about 10 seconds). A single blink indicates that the timer is reset to 1 1/2 minutes. Repeat the procedure and the light will blink twice, resetting the time to 2 1/2 minutes. Repeat again for a 3 1/2 minute interval, etc. up to a maximum of four blinks and 4 1/2 minutes.

I have a 1995 Sear garage door opener that stopped working


The trolley (the part that moves back and forth and is connected to your door) of your opener is most likely jammed against the bolt just in front of the motor unit. You can remove the bolt or loosen the chain until your unit will run. Once the door is closed find the 'up limit' on the side of the motor unit and turn it about 3 turns in the opposite direction of the arrow printed on the cover. Now replace the bolt or tighten the chain. Whichever you first did.

Sears/Craftsman Garage Door won't budge


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.
