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

1 Answer

I cannot get the door to open right. It can take up to ten pushes with the car bumper 1 foot from the door, moving the remote in all different directions, very frustrating. I have: 1. changed the batteries on all the remotes 2. I even bought a new lift master remote online, and that one does the same thing 3. The antenna is un affected and straight and nothing in its way. That's when I knew it was likely the I'm at a loss. Jim

The receiver is part of the logic board. The part number for the logic board is on the same end as the small antenna. It starts with 41A.

How do I open the fuel door on a 2007 chevy avalanche

My guess is the rubber bumpers for the fuel door are missing causing the door to sit in too far. Probably need like a pocket screwdriver to pop it open. New bumpers are available.

Garage door remote does not open door

I think you'll need to reset the wireless connection. Try pushing the button on the machine, then something on the pad. (or vise versa)

Remote does not open or close garage door; inside button flashes

What has happened is that you electric eyes are blocked or have gone out. The eyes are at the garage door about a foot of the ground on both sides. There should be a red or green light on one of them. If not some thing is blocking the beam that goes across the door. It is a safety beam so kids can nt get hurt when the door is coming down. If the beam is broke the door will go back up.
