Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
My Craftsman garage door opener works with the wall console, but not the remote. I found out the wall console was locked somehow, fixed that, but meanwhile I had changed batteries in both remotes. Now, neither remote works, only wall console. Tried to erase all codes, but didn't work. Any suggestions? My garage door opener will not work with the remotes or my car's Homelink system. I've replaced all batteries, cleared all codes, and reprogrammed all remotes and Homelink. The garage door will open once or twice but then ceases to work from remotes. Prior to my troubles the remotes and Homelink worked intermittently.
Look for a smashed wire between the motor unit and the wall button.
If the wire is smashed the insulation becomes so thin that power will leak thru the insulation.
Loosen the staples with a small screwdriver and slide the wire about ½ inch to move any areas of thin insulation away from the staples.
The second thing would be a bad wall button or a remote with a sticking button.
Or a remote in someone’s purse that gets the button pushed by other stuff in the purse.
The test is to disconnect the push button wires at the power unit. If the interference stops you have located the problem. If you reconnect the wires and disconnect the wire at the wall button this will tell you if the problem is the wire or the button.
