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

1 Answer

Craftsman Garage door opener

My garage door will not stay "connected" to the trolly part. Sometimes it does and sometimes it does not. If not, the trolly moves back and forth and the light comes on just as it would if it were connected. I have tried pulling it back on with the hand pull but if it doesn't want to connect it just won't. Then one time you hit the button and it hitches on and works again. There seems to be no rhyme or reason to it.
Thanks for your help.
I couldn't get this to accept the correct model info. It is a Craftsman 1/2 HP Model no 139.53535SRT1

I would just have someone come and check it out to see if it is the light or the electrical. Hopefully it is only a matter of cleaning it off and and replacing a piece or two. Good luck with the repairs and hopefully it is nothing to serious.

It sounds like the door is traveling too far in the down direction. When it hits the floor the safety causes it to reverse to the open position. You need to adjust the 'down limit' not the force.

My garage door sometimes gets stuck and then goes


Don't tighten the chain. It sounds like you have either a broken door spring or the drive gear in the motor unit is going bad. Release the opener from the door and operate it by hand. It should be easy enough to raise that your wife can do it with no problems and it should stay put when released about waist to shoulder high.

Loosen the chain enough that you can remove it from the pulley on top of the motor unit. Now with the door closed run the motor until the pulley turns in the clockwise direction and stops. Put the chain back on the pulley and tighten. You may have to tweak the up and down limits now.

Remotes quit working on Craftsman 53975 garage


It sounds like you have a logic board problem. If your remotes work at all it is not a programming problem. You could pull the logic board and check for loose connections especially around the small transformer. 18 years for an opener is very lucky. Their average life is about 1/2 that.

Garage Door won't close!


If the main light flashes 10 times when the door reverses it is a problem with the door sensors. Make sure the small light on each sensor is lit and not blinking ever so slightly. If it doesn't flash it is most likely the RPM sensor which is a small printed circuit board just in front of the motor. There is also a possibility that the down force needs to be increased. This is a control on the rear of the motor unit near where all those white wires go. Increase it about a quarter turn.

You most likely have a broken door spring. Release the door from the opener and try lifting it by hand. Look above the door for the springs.
