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

1 Answer

I have a craftsman diehard garage door opener. It has a sensor that the dog knocked offline. I have placed it back and get a green light meaning the beams line up, but you still have to hold the close button down until it is closed. Is there a reset button or something.

It means your sensors are properly aligned. Are you having a problem?

If the lights in the door sensors do not light you have either a bad logic board or bad wiring to the sensors. Replacing the logic board is usually the cure.

6 month old garage door will work.


On the back of the opener near where all those white wires go you will find 2 controls. One is labeled "up force." Increase this about 1/4 turn.

1/2 HP Sears Liftmaster will not close


YOU PROBABLY HAVE A BROKEN WIRE ON THE SENDING EYE. THIS WOULD CAUSE IT NOT TO LIGHT AND THE RECIEVER NOT TO GET A SIGNAL MAKING IT NOT LIGHT.

YOUR DOG IS PROBABLY THE CULPRIT AGAIN . THEY TEND TO SNIFF AROUND OR JUST GENERALLY BUMP INTO THE WIRES (SOMETIMES THEY CHEW THEM).

IF NO OBVIOUS BROKEN WIRES OR LOOSE CONNECTIONS CAN BE FOUND. YOU CAN TEST THE WIRING BY USING DOOR BELL WIRE TO TEMPORARILY REPLACE IT - THE FAULT COULD BE INSIDE THE WALL OR UNDER A STAPLE WHERE THE WIRES GET SMASHED (THIS ONE WE CAN'T BLAME ON THE DOG) :)

IF YOU REWIRE COMPLETELY (PAY ATTENTION TO THE POLARITY OR THE TEST WILL NOT BE VALID) AND THE LEDS STILL ARE NOT ON YOU COULD HAVE A DEFECTIVE EYE

One green and one yellow light


jasonbonefa remove the cover and check the drive gear. It is most likely stripped.

If the sensor lights are on it means they are working.

I have a liftmaster door opener and one of the saftey sensors always has a yellow light instead of green.


That is correct and not a problem.  One light should be yellow which means power and one light should be green which means the lights are lined up.
