My remote control will not activate the garage door:
Verify the lock feature is not activated on the door control.
Reprogram the remote control.
If the remote control will still not activate the door check the diagnostic codes to ensure the garage
door opener is working properly.

will move in the down direction.
o
Verify the safety reversing sensors are properly installed, aligned and free of any obstructions.

If the receiving sensor (green LED) faces direct sunlight, switch the receiving sensor with the
sending sensor so the receiving sensor is not in direct sunlight.
