MyQ Garage Door Photoelectric Eye Misaligned: How to Fix It

Q: Why does my MyQ garage door keep reversing when trying to close?

This usually indicates the photoelectric sensors are misaligned or blocked. Check for obstructions in the beam path and clean the sensor lenses. If the problem persists, adjust the sensor alignment until both LEDs show proper status lights.

Q: What do the LED lights on my garage door sensors mean?

The sending sensor typically shows a steady amber or yellow light when working properly. The receiving sensor shows green when aligned correctly, red or blinking when misaligned or obstructed. Both should be steady, not blinking.

Q: How often should I clean my garage door photoelectric sensors?

Clean the sensors monthly or whenever you notice the door acting erratically. Dust, spider webs, and outdoor debris can accumulate quickly and interfere with the safety beam.

Q: Can I bypass the photoelectric sensors if they keep malfunctioning?

Never permanently bypass or disable the photoelectric sensors as they are critical safety devices. If sensors repeatedly fail after cleaning and alignment, they may need replacement. Consult a garage door professional for proper diagnosis.

Q: Why won't my garage door sensors stay aligned?

Loose mounting brackets, vibration from door operation, or damaged sensor housings can cause alignment issues. Check that all mounting hardware is tight and that the sensor brackets aren't bent or damaged.

Abstract

The MyQ photoelectric eye misalignment error occurs when the safety beam sensors on either side of your garage door are not properly aligned or when something is blocking the invisible beam between them. This is a critical safety feature that prevents the door from closing when an obstruction is detected.
