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

1 Answer

Chamberlain Liftmaster GDO just clicks, no lights no open/close

Chamberlain Liftmaster series GDO, has been working just fine for 5 years. Suddenly it acts dead, as if no power. Remotes, inside hard wired control, nothing shows power, no light bulbs work. Pushing remote button or manual button unit 'clicks' but no action.

One door sensor light was out, thought that was bad, replaced that, so both lights have indicator, still no change. There were thunderstorms at the time, maybe power surge? Everything I find seems to point to replacing the logic board, but hate to spend $$ if it doesn't fix the problem.

I've unplugged the unit overnight to 'reset' no change. The 'learn' led flashed bright 5 times, that points to overheating.

Pull the logic board and check it for burnt or missing traces on the printed circuit. Thunderstorms love logic boards.

Sounds like the battery in wall unit is low, or it needs to be programed for the opener. If you are not comfortable programming remote you may have to cal a GDO company. You can call Chamberlain and the will help you.

If the door is heaver than the original you may to adjust the opening force and the closing force. Check your instructions. The closest gdo I found was a chamberlain 8500. Go online to

Chamberlain chain gdo. goes all the way up until it hits gdo box and gets stuck. unstick it and it works for awhile then it happens again


Unstick it and close the door. While the door is closed locate the 'up limit' control on the side of the motor unit. Turn this control 2 full turns in the opposite direction of the arrow printed on the cover. Should be good to go.

Chamberlain GDO light turns on randomly at any time of day or night. (Whisper Drive with Motion-Detecting Control Panel 935CB.)


If you don't have any puppies or strange animals running around your garage I would disconnect the wall control for a couple days. If your problem stops I would suspect that control. If you have a heated garage I would also make sure there is nothing that could be moving from the air movement from the furnace.

My Liftmaster GDO makes a clicking sound and won't open


See if the trolley is jammed against the bolt just in front of the motor unit. If so remove the bolt and then run the opener until the door is closed. While the door is closed locate the 'up limit' control which is on the side of the motor unit. Turn this control 2 complete turns in the opposite direction of the arrow printed on the cover. Remember to replace the bolt.

The motor will need rewinding, and the condensor will probably need replacing.
That should do it:)

Liftmaster gdo won't operate with door or remote


Hi there, when the problem first started was the door being used frequently? If your GDO was used quite a few time's in a short period of time the "overload" may have triped. The makers of all GDO's now adays install an overload witch is an electrical safety device protecting the motor. This prevents over heating in turn burning up the motor. To rectify unplug for 15-20 mins. If you have Model number 1270 turn to pg. 7 in owners manuel. Insure all door locks are free. Insure power to electrical outlets by pluging desk lamp in same out as GDO. what model do you have?
