Reprogram the remote. Press the learn button on the back of the opener and then press the remote button until the light on the opener blinks once.

SOURCE: Garage Door Remote Not Working Consistently

Had and still have the same problem. Sears refuses to fix, but acknowledged that the problem is caused by rf interference with their 315 mhz frequency use by motion sensors, etc... They will not post this on a web site or any advertisement. They will not put in any manual, nor do they have any fix. I took off and threw out a motion sensor on my light and innitially fixed the problem. I recently installed a water fountain bird bath with six small LED lights in a front garden, which shut down my remotes AND my home links in my cars. The probl;em has been isolated to the LED lights! Sears advised that Chamberlain makes their garage door openers. Chamberlain blamed the water fountain manufacturer. Both refused to fix. I am switching to a Genie which operates at 390 mhz.

meerkat1 your receiver has quit working which is part of the logic board. The logic board runs around $80.00 for the part alone. Might be time to get a new opener.

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.

HOPE THIS HELPS

ANY TIME YOU CHANGE THE BATTERY IN A REMOTE IT NEEDS TO BE REPROGRAMED.

Did the remote and keypad work before you changed the battery? Changing the battery in the keypad should not affect the remote.
