My liftmaster 2265 1/2 hp remote does open BUT DOES NOT close garage door. I tried reprogramming, but no success. What to do? how to fix?
If the door starts to close and the main light flashes 10 times and the door reverses to the open position it is a problem with the door sensors. Make sure they are pointed at one another and they each have a small light that must be on and not flickering.
If it starts to close but reverses and the main light does not flash 10 times it is possibly the RPM sensor which is a small printed circuit board just in front of the motor.
