Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
Can you help?
My gears were finally shredded on my 15+ y/o Crafstman 1/2hp motor - so I replaced it with a 3/4 new model. I left the door hardware and simply replaced the motor, kept the chain. I have a 15 ft wooden door.
It worked very well for about two days after I had dialed it in using the force/travel adjustments, but yesterday, it started bouncing up off the floor. I turned down the down travel as far as I could go (and it still bounced). It looks like its really pushing hard when the door is closed, then reverses.
I played with both force and travel - and nothing seems to work.
The upward travel works like a charm, I can dial that in to stop 2-3" from the stop bolt - and it works as it shoud. Down travel seems "broken."
Open up the caseand look at the travel assy. Sometimes the limit (up or down) do fall off the assy. Just snap it back on.
