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

1 Answer

Craftsman 1/2 hp moves chain 5-6 inches and goes in reverse.

Then it stops and flicks the light 3 or 4 times. It is a used unit that I just bought yesterday. It is supposed to have the electronic sensors but they didn't have those. Before I go buy the sensors, I'd like to make sure that the unit is going to work. Is there a way to fool the unit into believing that the sensors are there (or bypass)?

Thanks,
Gary

There is no way to bypass the sensors and it is acting normal for an opener without sensors.

If the main light flashes 10 times and the door reverses to the open position it is a door sensor problem. Make sure the lights on the sensors are both on and not flickering. Tweak them if necessary. If you cannot get both lights to come on you have bad sensors or the wiring to them.

Most common cause of the problem you describe is a bad start capacitor. Remove the cover from the motor unit. The capacitor is about 5 inches long and 2 inches in diameter.

Motor moves 5 in" and reverses and light blinks 5 times


In the manual it says if you can hold the wall button down & door closes. You have a short in the wiring to the reciever eye. Try substituting some new bell wire in its place, or test the wires for continuity.

Opener will not reverse


FIRST YOU NEED TO RESET THE CHAIN .

Unplug power
Release the door from the opener close the door manually. take the chain loose and slide the traveler down to reengage with the trolley. Plug in power, run the unit with chain off untill it completes a clockwise cycle and stops. reconnect the chain and set tension.

Adjust the chain tension.

If it still moves 6-8 inches and flashes 5 times. the problem is in the rpm sensor.
