My lift master wall mounted control is blinking The door functions properly with the wall mounted control pad, not the remote. I held the lock button down for 5 seconds and even unplugged the garage door opener for a few minutes, but control panel still blinks. Do I need to replace the control panel?

I had this problem as well with the door opening just fine but was not closing when using the remotes or when breifly pressing the wall mounted control. The door would close only when using the wired wall mount control. I have experienced this problem with other garage door openers I've had in my previous homes and it was always caused by sensors at the bottom of the door tracks being either misaligned or the lenses were dirty. In this case, and it was just a moment ago today, I simply cleaned the sensor lenses and then the door began to function properly. Give it a try.

Make sure the light in the wall control is not blinking. If it is press and hold the lock button on the wall control for 3 seconds.

The most likely problem here is that your wall control is bad. I would disconnect the 2 wires going to it and I think you will find your remote works. Replace the wall control.

Check to see if the small light in the wall pad is blinking. If so press and hold the button with the lock icon for 3 seconds.

If this isn't the case your receiver may have failed. The wall button works without the receiver;

I would remove the logic board and look for loose or missing traces on the printed circuit board.

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.

It is related. One of the buttons on your wall control is the lock button and has a lock icon on it. Press and hold it for 3 seconds. The blinking should stop and your remote should now work.

Hold the button with the lock icon in for 3 seconds. This should toggle the unit off vacation mode and your remotes will work.
