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

Chamberlain 1/2hp won't open/close and learn LED flashes 5 times

My Chamerlain 1/2hp opener won't open or close, and the motor hums for a few seconds when I try to activate it. It actually sounds as if the motor tries to move in one direction then the other before it stops. Also, the LED light next to the transmitter button flashes 5 times, pauses for three seconds, then repeats the 5-flash cycle. Any ideas?

The gear needs to be changed kit #41c4220a. Be sure to change the bottom bushing on the motor mount.

Liftmaster 1245 led blinks five time but door will not open


5 flashes of the LED is the code for "RPM sensor or motor overload." You can try unplugging the opener for about 15 minutes to see if it resets itself. Normally if it is the RPM sensor the motor will run for a few seconds and then turn off. Is the door not opening or not closing? Just checking to make sure.

On the back of the garage door opener there is a red button. Depress this button and sync your keypad to the opener. This will re-establish the code and reset the remote.

Craftsman GDO don't not respond other than a click noise when remote or wall unit is pressed. When power is removed, then restored, wall switch is pressed, unit clicks, then green LED on back of unit...


The unit is flashing the code for 'motor overheated or RPM sensor failure'. If the door is stuck in the open position it could be because the trolley is jammed against the bolt just in front of the motor unit. Remove the bolt and run the opener until the door is closed. Now on the side of the motor unit you will find the 'up limit' adjustment. Turn this 2 full turns in the opposite direction of the arrow printed on the cover. Be sure to replace the bolt.

I have the same problem.The garage door opens or closes on its self after setting up the new remote chamberlain. i foun out every time my nabour closes his garage door mine opens.


Look at the LED light next to the SMART/LEARN button on rear of the motor unit. You may need to remove a light lens cover in order to see it. If the light is flashing rapidly this means you have a stuck button on one of your remote controls. Take the batteries out of each remote control. When you remove the batteries from the bad remote, the light will stop flashing. This remote needs to be replaced.


If one of your neighbors remote controls is inadvertently programmed into your receiver, you door will open when their remote is activated. If this happens you will need to clear out your receiver and reprogram your remote controls. Press and hold the smart/learn button for 6 seconds or until you see the small LED light near the button turn itself off. If the above steps have been followed and the symptoms continue, there may be an electronic short in either the wall control button or the receiver logic board. In this case, remove the wall control wires from terminals 1 and 2 on the motor unit. Should the symptoms persist after the wires are removed, replace the receiver logic board. If the symptoms stop with the wall control wires removed from the motor unit, replace the wall control button, and the wires leading to the wall control button.

Craftsman Garage Opener Clicks only and LED blinking 5 times


Just fixed this problem tonight. Had the 5 blink/flash thing. Opened it up and saw that the motor wasn't spinning so it wasn't a bad rpm sensor. Jumped the red to black and then the blue to black to verify motor worked. At that point assumed it was the logic board not telling the motor to start, but I could hear the click of the relay. Pulled the logic board out and noticed a solder joint that had failed directly behind one of the relays. Resoldered that joint and the garage door opener worked again like a dream. Hope that helps someone else.
