The remotes use the receiver and the wall control doesn't. I would pull the logic board and look for burnt, loose or missing traces on the printed circuit. It may have just failed.

Make sure the green light in the wall control is not flashing. That locks out the remote. If it is press and hold for 3 seconds the lock button on the wall control. It could just be that your remote has failed.

Garage door wont work with remote


If the small light in your wall control is blinking it is in the lock mode. Press and hold for 3 seconds the button with the icon of a lock. This will toggle the lock function off.

HI, the wall remote for my 976LM light is blinking but if I push the open/close button it does open the door although the car remote won't open it, i've replaced batteries but it doesn't help. Any advice?


One of the buttons on your wall control has an icon of a lock. Press and hold this for 3 seconds and release. The blinking should stop and your remote should work.

Garage door opener remote won't work


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

Remote does not open garage door


It sounds like the wall button has the lock feature engauged.

Is there a small green LED flashing inside the wall button?
Push and hold the lock button for about two seconds and the LED should stop flashing. This will unlock the garage door opener and your remotes should start working. You may have to reprogram your remotes and homelink again since you triedprograming in the lock mode.

Good luck.

REMOTE CONTROLS WILL NOT WORK-WALL BUTTON FLASHING RAPIDLY


Does your wall switch have a lock feature? By pressing the lock button, the remote control is disabled. A flashing light indicates this feature has been activated.

To deactivate, press and hold the lock button for 2 seconds. The flashing should stop and your remote should work again.

Garage door remote won't open the garage door


The little button with a padlock on the wall control is a "vacation" lockout feature that disables the remotes. There should be a small LED on the wall control that is always on steady. When the padlock button is pressed and released the LED should be constantly blinking (indicating the vacation lockout mode is active) and your remotes should be disabled. The wall control will still operate the door. Pushing the padlock button again should make the LED stop blinking and restore the door to normal operation.
