The sensor eye - or more likely, the other end, the sensor light - probably got knocked out of alignment. The eye should have an LED on it - possibly one that glows green when it's ready to close or red when it's obstructed or out of alignment. Try adjusting the light until the LED on the receiver glows green.

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

Usually this can be corrected by programming the opener. Locate the smart/learn button on the back of the opener. It is just to the left of all those white wires. Hold the button down on your remote and then press and immediately release the smart/learn button. Do this for each remote you have.

FIRST CHECK TO SEE IF THE LOCK/VACATION BUTTON ON THE WALL CONTROL HAS BEEN ACTIVATED. THE LED ON THE WALL CONTROL WILL BE FLASHING. - SIMPLE SOLUTION PUSH THE LOCK BUTTON AND HOLD FOR 2 SECONDS TO TURN OFF LOCK FUNCTION.
SECOND TRY TO REPROGRAM THE REMOTES TO THE UNIT - THEY WILL SOMETIMES LOSE MEMORY IN AN ELECTRICAL STORM.
IF REPROGRAMMING DOESN
