Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
I have a chamberlain garage door opener. when I press the button to close the door the motor makes a sound then stops and but nothing happens. It looks like it is trying to open it instead of closing. I verified this by removing the chain and saw the gear turns in the direction of openning the door even though the door is already up. I also see an led light blink 5 times and stop then repeats.
Isn't it supposed to reverse direction if already at end of it's travel.
Thanks for your help in advance.
FIRST YOU NEED TO RESET THE CHAIN .
Release the door from the opener close the door manually. take the chain loose and slide the traveler down to reengage with the trolley. Plug in power, run the unit with chain off untill it completes a clockwise cycle and stops. reconnect the chain and set tension.
Adjust the chain tension.
If it still moves 6-8 inches and flashes 5 times. the problem is in the rpm sensor.
