Try this. Press and hold the smart/learn button for 6 seconds. This will erase everything from its memory. Now press and hold the button on one of your remotes while you press and immediately release the smart/learn button. Do this for each remote.

Find the model number for your opener. It will start with 139. Check to make sure you have the correct keypad. There are several models and the wrong ones will cause the problem you have.

The first solution does work. Even though instructions say to wait six seconds before letting go (when light starts to blink), releasing both buttons immediately fixed the problem for me.

My opener seems to forget its program and needs frequent reprogramming


you are getting a break in power somewhere, perhaps a bad circuit board in the motor itself. the least expensive is to try a new remote.

The remotes for my craftsman garage door opener will not reprogram. the light on the rear of the unit does not blink when I try and reset / reprogram the remotes.


Anytime you cannot program more than one remote it is the receiver that has quit working. The receiver is part of the logic board.

The correct way to program a remote is to hold the button down on the remote and then press and immediately release the learn button. If this doesn't work your logic board is bad.

Chamberlain Whisper drive remote control unit not working


THE NEW REMOTE MAY NOT BE THE CORRECT SYSTEM FOR THE UNIT YOU HAVE.
THE ONE THAT DOESN'T WORK MOST LIKELY NEEDS A NEW BATTERY.
NOTE IT MUST BE REPROGRAMED AFTER CHANGING THE BATTERY

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.
