If the main light flashes 10 times when the door reverses to the open position it is your door sensors. Make sure the small light on each one is lit and not flickering. Tweak them a little. If you cannot get both lights to come on you have bad sensors.

Check your door sensors. Make sure they are pointed at one another and the small light on each one is lit and not flashing. Tweak them a bit. If you cannot get both lights to come on you have a bad sensor.

Press and hold for 3 seconds the button on the wall control that has an icon of a lock. The light should quit blinking and your remotes will once again work. Holding that button for 3 seconds toggles your openers vacation mode.

The problem is with your door sensors. They each have a small light that must be lit for them to operate and the sensors must be pointed at one another for the lights to be on. If they are properly aligned and you still cannot get one or both lights to come on you have a sensor that has failed.

Garage door won't open.


The most common cause of this problem is the door sensors have been bumped and misaligned. They each have a small light that should be lit and not flickering. Tweak them until they are pointed at one another and the lights are lit.

Door not opening


First, check the safety eyes. There should be a light on on each eye. If not realign until they come on. On the wall button if the green light is blinking press the lock button on the wall control for three seconds. The light will go solid. If either of these do not fix respond with more detail and I will help.
