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

1 Answer

I have a Chamberlane Lift Master Professional I went to open it yesterday and it would not open. When the button is pushed the unit just clicks and the controller light is blinking 5 times then pauses and then blinks again 5 times. The two sensers are lite one green and one yellow. The door opens freely when operated manually. I have unplugged and plugged in again and no difference. Any suggestions?

The code it is flashing is "RPM sensor or motor overload." It is not a door sensor problem. The RPM sensor is a small circuit board just in front of the motor.

The chamberlane liftmaster professional 1/2 hp garage door where I rent, had the door only replaced. Are there certain doors only that will work with this unit? It hasn't worked right since. 1

You need to adjust your force settings and reset your limits to match your new door. this very easy to do, pull up program instructions on your computer. Or contact the owner or property manager to see if they will send a garage door tech out to do this. should only be the cost of a service call 50 - 65 dollars.

I have a Chamberlain 1265 Lift-Master Professional. Does that model still exist or if not, what has replaced it. Also who carries it

I know that that is a lift-master opener. chamberlain owns lift-master. but if its a new opener your looking for try the lift-master 3800 jack shaft opener. it features a low profile design that mounts next to the door instead of on the ceiling above the door, and also incorporates a battery backup so that you will never be locked out again.

The most common cause of this problem is a bad wall control the wiring going to it. You can eliminate both temporarily by removing the wire at terminal 1 on the back of the motor unit. The wiring sometimes is shorted by the staples the installer uses. The wall control gets used a lot.
