Why Does My LiftMaster Garage Door Reverse Before Closing Completely?

Garage Door Openers • LiftMaster Garage Door Opener

Your LiftMaster garage door opener starts to close then reverses direction and reopens before reaching the fully closed position. This happens every time you attempt to close the door and the opener light may flash to indicate a fault. The reversal is caused by the safety reversal system detecting an obstruction in the door path, misaligned photo-eye sensors, or incorrect close-limit and force settings on the opener.

Why Is My LiftMaster Safety Sensor Showing One Yellow and One Green Light?

Garage Door Openers • LiftMaster Garage Door Opener

Your LiftMaster garage door safety sensors show one amber or yellow LED and one green LED. The amber yellow light is on the sending sensor which emits the infrared beam. The green light is on the receiving sensor which detects the beam. A solid amber and solid green means normal operation. If the green light is blinking or off the sensors are misaligned and the door will not close. The opener light may flash 4 times indicating sensor misalignment.
