Garage Door Sensor Repair

The two photo-eyes near the floor stop the door if anything crosses its path. When they're knocked out of line, dirty or wired badly, the door refuses to close. We realign, rewire or replace them and test the safety reverse.

Garage Door Sensor Repair

Signs you need safety sensor repair

  • Door goes down a few inches, then back up
  • Opener light blinks when you try to close
  • Sensor LED is off or flickering
  • Door only closes if you hold the wall button
  • Sensors knocked or hanging loose

What we do

  1. Clean the lenses and check for obstructions
  2. Realign the eyes and tighten the brackets
  3. Test and repair low-voltage wiring
  4. Replace failed sensors with matched parts
  5. Test the auto-reverse with an obstacle

Good to know

Low winter sun can blind a sensor at certain times of day, and a bumped bracket is the most common cause of all. If the wiring was stapled through, it will short again; we fix it properly.

FAQ

Safety Sensor Repair questions

Why does my garage door only close if I hold the button?

Holding the wall button overrides the sensors, which means they're blocked, misaligned or failed.

Can I bypass the sensors?

No — they're required by federal safety rules and prevent serious injury to children and pets.

How do I know which sensor is bad?

Usually one LED is off or blinking. We test both and the wiring between them.
