Hi. The green light was flashing and ny transmitter in the car would no longer operate the door. On the back of the liftmaster, just below wker the small wires go in, there is a small, flat, green button. I pressed that with a stick and it solved the problem.

Same thing on my Liftmaster -- the button was red. Pushing it lit up an L.E.D. next to it, the green light on the door opener wall-mounted switch stopped flashing, and the door opener resumed normal operation. THANKS!

The end is near. No just kidding. It sounds like your opener is in 'lock' mode. If you have the wall control with 3 buttons, press and hold the button with the lock icon for 3 seconds. The flashing should stop.
