Chamberlain MyQ Garage Door Error: Door Will Not Close - How to Fix It

Q: Why does my Chamberlain MyQ garage door close but then immediately open again?

This usually indicates the safety sensors are detecting an obstruction or are misaligned. Check for objects in the door's path and ensure both safety sensor lights are solid, not blinking. Also check if the door's closing force settings need adjustment in the motor unit.

Q: Can I bypass the safety sensors to close my garage door?

While you can temporarily hold the wall button to close the door with misaligned sensors, this bypasses important safety features. It's not recommended as a permanent solution since the sensors prevent injury and property damage. Fix the sensor issue instead of bypassing safety systems.

Q: How do I know if my Chamberlain MyQ safety sensors are working properly?

Working sensors will have steady LED lights (one green, one amber/red) and the door will close normally. To test, start closing the door and wave an object through the sensor beam - the door should immediately stop and reverse. If it doesn't, the sensors need service.

Q: What causes MyQ garage door sensors to go out of alignment?

Common causes include vibration from the door's operation, accidental bumping while parking or moving items, temperature changes causing expansion/contraction, loose mounting hardware, or settling of the garage foundation over time.

Q: Why is only one safety sensor light working on my Chamberlain garage door?

If one sensor light is off, check for loose wire connections, damaged wiring, or a defective sensor. The sending sensor (usually amber/red light) powers the receiving sensor, so connection issues typically affect the receiving sensor first. Clean both sensors and check all wiring connections.

Abstract

When your Chamberlain MyQ garage door won't close, it's typically due to misaligned safety sensors or an obstruction in the door's path. This safety feature prevents the door from closing when it detects potential hazards, protecting people and property from injury or damage.
