    Garage Door Repair

    Garage Door Sensor Repair in Massachusetts

    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.

    PART 01

    Torsion spring

    What it does
    Counterbalances the door's weight so it lifts with little force.
    How it fails
    Snaps with a loud bang after ~10,000 cycles; the door won't lift.

    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.
