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

1 Answer

Garage door works sometimes and sometimes it won't

The remote seem to be working fine. But sometimes when I try to open the door it only goes up half way or part way. Closeing the door is never a problem. The door seems to be difficult when the temp is on the rise. I live in Iowa and right now it's cold, door working fine. I've tried to adjust the chain, up and down tention on the motor. Nothing works for very long. Can you offer and help. Larry

How do I make it stop at 6 inches open using my car remote?


You have to press the button on the remote 3 times allowing for the little delay that comes with remotes. the wall switch is easier because it is wired directly to the opener. you will also find it sometimes works easier if you start with the door all of the way down.

My garage door will only open half way. It appears to be getting stuck when it is opening.


If you haven't gotten your issue fixed yet... I had the same problem (stopped opening half way when using the remote, went down fine, could lift/close manually fine as well) and this happened on our first cold weather day of the year which was very telling. Anyhow, there are two gauges/dials on your garage door opener unit itself (above, where the light is) which controls how much torque/strength your door uses to open or shut through resistance. I turned mine up some and it now works fine; what likely happened was that the metal tracks or the wood frame condensed in the cold and was providing just enough resistance to stop it when opening - as they have a security device built in to stop if they meet any resistance. Hopefully this helps!

Last night none of the remote controls worked (the one that came with the garage door opener or the remote Home link from our vehicle) The keypad also did not work. This morning, I erased all of the codes...


First thing I would do is remove the wire from terminal #1 on the rear of the motor unit and try your remotes. This wire goes to the wall control and it sometimes causes the remotes to quit. If this doesn't correct the problem then I suspect a bad logic board. Especially if you have had any electrical storms.

Garage Master 1/3 HP 1997 Door Working, not responding to Remote


I have the exact same situation, except my model (139.53607) is older than yours and does not even have an LED. Remotes only works after after shop light goes off (5 minutes or so), but wall button works fine. Did call Sears Service and the tech told me the logic board is probably shot. Don't want to waste money on service call so I'll probably have to buy a completely new unit in the Spring and go through the winter without the use of a remote.
