Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
I opened the door and now it won't close. I can hear a relay clicking inside but the door won't move. On the learning Indicator it blinks 5 times and then has a pause. Any one with info would be greatly appreciated.
Most commonly this is caused by the trolley jamming against a bolt just in front of the motor unit. Remove the bolt and run the opener until the door closes. On the side of the motor unit you will find a control labeled 'up limit'. Turn this about 3 turns in the opposite direction of the arrow printed on the cover. Be sure to replace the bolt. Should do it for you.
