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

1 Answer

Garage door motor does not operate

I have a sears 1/2 horse model 139.53975srt1. The motor does not seem to come on. when I push the wall switch,keypad switches etc all I hear is a click coming from the unit. everthing else seams to work properly(lights, photo-electric door sensor) the unit is not very old(7 yres)

note: i dont know if this matter but the keypad back lighting also blinks a few times after I punch in the code(i dont recall if this is normal)

I unplugged the main powerfrom the outlet to "reset" it but no luck.

any help would be appreciated

Why doesn't the door move when i press the wall button it just hums?


Anthony, Since It's humming you know it's getting juice. It could be the the same exact problem I had on our Sears Liftmaster. First remove the cover and check the set of nylon gears to see if they try to move when you push the button. If so, the motor is probably ok.
The gears operate off a worm drive and come as a set, and sometimes they jam or are worn out. If the motor runs after pulling the gearset it's good. Go to Chamberlain for the parts. They're cheaper and faster than Sears. If want a diagram, for that model google one form their website and you can see how to take it apart. Ken

Garage door motor dead


Keep checking for loose wires. Nothing about changing the gear should cause the motor to stop running. Check the wires on the start capacitor and follow the white wire from the motor and make sure it is connected.

I have a Sears Craftsman 1/2 horse garage door opener. When I push the button, I can hear it hum, but the chain won't move and it seems the sprocket is frozen?


If your door is stuck in the open position you will find the trolley is jammed against a bolt just in front of the motor unit. Remove that bolt and run the opener until the door closes. Now locate the 'up limit' control on the side of the motor unit and turn it 2 times in the opposite direction of the arrow printed on the cover. Replace the bolt.

Motor works but does not move chain on half horse sears


Clutch? need more info.. wall mount or overhead? If it's wall mounted it could be the clutch, I don't think overheads have a clutch though. The first thing I'd do is get on a ladder and see if the chain is still attached to the sprocket... good luck

My door comes down part way and the motor keeps running.


Sounds like the gears might be out of the operator. If you can remove the cover see if there are white shavings in the cover. A Craftsman operator will take gear kit # 41C4220A

Chamberlain Liftmaster Pro. Garage door Problems closing


The sensor eye - or more likely, the other end, the sensor light - probably got knocked out of alignment. The eye should have an LED on it - possibly one that glows green when it's ready to close or red when it's obstructed or out of alignment. Try adjusting the light until the LED on the receiver glows green.
