Problem for Sears Craftsman LiftMaster Chamberlain Garage Door Opener...
I just installed a sears craftsman 1/2 hp garage
By johnnykay86 on Oct 19, 2009
i just installed a sears craftsman 1/2 hp garage door opener. when i close the garage door with the remote the chain track bends up just about 12 inches before it closes all the way, and this only happens when the door is closing and not when it's opening.. can anyone give me some advice. thanks John

What is wrong is you need to adjust the limit on the door when it comes up. What it is doing is coming to far back on the track. You need to push the back limit forward away from the motor so the door does not come back and drop down on the inside of the garage. The opener is trying to push the door up hill to get it to close that is why you are getting the bend in the track.
Good Luck
