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

Garage Door Remote


Did you happen to put a new light bulb in it? I put an LED bulb in mine and the interference caused the remotes to stop working. I had a bear figuring it out, because it seemed to be totally random. Sometimes they would work and sometimes they wouldn't. Once I switched back to an incandescent, it worked fine.

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.
