Check wiring back to unit to make sure it's not shorted or broken. You can also reset the garage door opener by unplugging it for a few minutes and plugging it back in.

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.

I have flashing green light on the wall control panel and the door will not open.


At a guess, you have to re-teach the power unit to read your remote control. First check there's a good battery in the remote control.

Without instructions, I can't say but here's the url to liftmaster, just enter your details to get to the correct instruction set.:-

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.
