This is almost always the result of a dirty or obstructed safety feature.
Garage door closes to sensors and reverses.
You push the button to close the garage door.
The photo eyes send an infrared beam across the bottom of your garage door opening if that beam is broken the door will reverse.
If the door closes and reverses it is traveling too far and you should decrease the travel.
Test the sensor eyes by connecting them to short wires directly at the motor unit.
If the door reverses part way down and you are sure there is no obstruction or binding increase the closing force a small amount and try it again.
If an object person or animal blocks the beam the closing door reverses direction.
It goes partway down reverses direction and goes back up again.
While holding the sensors close together and facing each othe click the remote.
If the door doesn t close and the lights don t blink replace the safety sensors.
A garage door that keeps reversing when you attempt to close it with the opener might have a simple problem or a major issue that requires a service professional.
Clean and adjust the photoelectric eye which also reverses the garage door.
