Garage Door Opener: Reverses on its own

If the garage door only travels down an inch or so before reversing, something is probably blocking the beam between the two safety sensors at the bottom of the rails, or they're not aligned. But if the door closes before reversing, the problem is the travel limits or force limit settings. If all the settings are correct, damaged tracks could be interfering with the travel of the door.

Adjust and align the garage door opener

Safety sensor kit

When the garage door opener doesn't work operate properly, check the alignment of the motor unit and/or the rail and realign if necessary.

Replace the garage door opener safety sensor

Safety sensor kit

The safety sensor has a pair photoelectric eyes at the base of the rails—one eye emits an infrared beam and the other receives it. If an object, person or animal blocks the beam, the closing door reverses direction. Test the sensor eyes by connecting them to short wires directly at the motor unit. 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.

Replace the garage door opener RPM sensor

RPM sensor

The RPM sensor monitors motor shaft rotation and sends speed signals to the logic board. The logic board shuts off the motor and flashes the learn light 5 times when it doesn't receive speed signals from the RPM sensor. The door only moves 6 to 8 inches and then stops when the logic board isn't receiving speed signals. Replace the RPM sensor if the door only moves a short distance and the learn light flashes 5 times.
