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

Light flashing after opening

Hi I have a liftmaster 2000 remote garage door opener.

After opening the door, during the brief period when the light should be on, it flashes on and off rapidly and I can hear the relay clicking.
The unit will not respond to the remote control during this time.

After a while the light stops flashing and it is possible to close the door.

At first I thought it was a faulty blub but the replacement does the same thing. I have reprogrammed the remotes and reset the unit but still have this problem.

thanks
Steve

If your sensors are not pointed at one another the light on one of them will go out. Tweak them a bit. If you cannot get the light to come on then your sensors are bad.

I would first of all unplug the opener for at least 15 minutes and see if it doesn't reset. If not, pull the logic board and check for burnt or missing traces on the printed circuit board.

To answer your question the opener is in vacation mode. Press and hold for 3 seconds the button on your wall control with the lock icon. The green light will stop flashing and you will be back in business.

My liftmaster 2265 1/2 hp remote does not close


If the door starts to close and the main light flashes 10 times and the door reverses to the open position it is a problem with the door sensors. Make sure they are pointed at one another and they each have a small light that must be on and not flickering.

If it starts to close but reverses and the main light does not flash 10 times it is possibly the RPM sensor which is a small printed circuit board just in front of the motor.

Green light is flashing on my garage door opener on the inside of my house/craftsman opener


Hi. The green light was flashing and ny transmitter in the car would no longer operate the door. On the back of the liftmaster, just below wker the small wires go in, there is a small, flat, green button. I pressed that with a stick and it solved the problem.
