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

1 Answer

Door goes up and down but light does not work

I have a 1/2 horse chamberlain opener and the door goes up and down using the remote openers and the mounted button. The problem is that the light does not come on when raising the door or breaking the sensor beam. The bulb is a standard 60 watt bulb and it works. This happend when the bulb blew. Also I can program 2 remote openers to work using the set button on the opener but I can not get a third remote opener to work and when I try it deactivates the other 2 openers.

Sears craftsman 1/2 hp. Door goes up with remote, but when button pushed to go down the light flashes and door doesn't move. If you push the wall mounted switch, the door goes down like normal. Works...


Check the sensors in the doorway. They should both have a small light that is lit and not flickering. Tweak them a little. If you cannot get both lights to come on you have bad sensors.

The remotes opens the door when we leave. The remote will not close the door. Only the wall button will close-we have to hold it down until it is fully closed. Craftsman 1/2 horse 41A5021-3H


Check your door sensors. Make sure they are pointed at one another and the small light on each one is lit and not flickering. Tweak them a little. If you cannot get both lights to work you have a bad sensor.

My opener is a 1/2 horse lift master professional chain drive . The door will not close unless you hold the closer button in. From the remote it will only move a few inches and then reverse. The door works...


If the main light flashes 10 times when the door reverses it is a door sensor problem. If not, you probably have a bad RPM sensor board which is a small printed circuit board just in front of the motor.

Sears 1/2 hsp garage door opener. Remote control will not close garage door until light goes out. what is problem ?


I would suspect you have a light bulb that is radiating and causing interference with the receiver. Remove the light bulb and try. You can also try this: Unplug the unit and using a small screwdriver pull out on the center connection in the light socket. This will tighten the connection and prevent arcing.

Garage door opener doesn't work with key pad or remotes


It sounds like for some reason the receiver has lost the stored codes for your remote transmitters. The wired button goes right to the opener so it continues to work.

On the back of the opener you'll see a small pushbutton. Press it and the indicator light nearby will come on. While this light is on, press the button on your remote. The light will go out and the code is stored. Repeat this for each remote. The process is the same for the keypad, except that you need to enter your desired 4-digit code.

If this programming doesn't work you'll need to replace the receiver board. Like any other piece of computerized equipment, it can fail or be damaged by power line problems. But try reprogramming first, as that's the most likely solution.

If this has helped you, please take a moment to rate the solution. Thanks for asking here!

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.
