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

1 Answer

My craftsman garage door opener won't close. This is NOT a sensor problem. I'm a mechanic by trade. I rebuilt the opener last year. Now even with the opener apart on the table, the motor won't go in the reverse direction.

The sensor light are different colors


The sensors are seeing something directly in line with the beam between the 2 sensors, or your sensors are not aligned so they point directly at each other.

My Liftmaster garage door won't open or close. I hit the button and it make a sound and clicks but won't close


Remove the cover and check the drive gear. It is a white nylon gear just in front of the motor. It will be obvious if it is bad. Tell me - if it won't open how do you know it won't close?

If when closing the door it reverses to the open position and the main light flashes 10 times it is a door sensor problem. Make sure the small light on each sensor is on and not flickering ever so slightly. (check closely) Tweak them a little even though they may seem to be okay. Check for 5vdc between terminals 2 and 3 on the rear of the motor unit. If there is no voltage or if it is greater than 6vdc the logic board is bad.

My liftmaster garage door opener will open the garage door but won't close it from the wireless remote in my car. what could be the problem


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

I had to manually close my craftsman garage door and now it won't respond via the remote or the wall button. Chains move but not engaging with door.


Look for a red handle with a rope attached along the bar from the main unit to the door. Pull this handle and release until it engages the track again.

Anytime the main light flashes 10 times and the door reverses to the open position it is a door sensor problem. If the transmitting sensor light is blinking it is bad.
