What Are Garage Door Safety Sensors?

Every garage door installed since 1993 is required by federal law (UL 325) to have photo-eye safety sensors — two small units mounted about 6 inches off the ground on either side of the door. They send an invisible infrared beam across the opening. If anything breaks the beam (a child, a pet, a car), the door stops and reverses.

When a sensor fails, your door legally cannot close on its own — and that’s a good thing. It’s keeping your family safe. But it also means you need it fixed.

Signs Your Sensor Needs Repair or Replacement

  • The door reverses just as it’s about to close (most common symptom)
  • The opener light flashes 10 times when you press close
  • One or both sensor LEDs are dark, blinking, or wrong color
  • The door only closes if you hold the wall button down
  • Sensors are misaligned, cracked, or hanging loose
  • Visible water damage or corrosion on the sensor housing
  • Cobwebs or dirt blocking the lens (sometimes this is the whole fix)

If holding the wall button forces the door to close, that’s the universal sign your sensor system is bypassed — and the door is no longer safe for kids or pets.

Common Causes of Sensor Failure

  1. Misalignment — bumped by a bike, broom, or car. Often a 30-second fix.
  2. Dirty lenses — Puyallup’s wet winters leave grime that blocks the beam
  3. Loose wiring — staples come loose, wires get nicked by lawn tools
  4. Water damage — sensors mounted too low can flood
  5. Sun glare — rare but real; the sun hits the receiver and overwhelms it
  6. End-of-life — most sensors last 10–15 years before the electronics fail

Garage Door Sensor Replacement Cost

Every sensor job is quoted individually, because the cost depends on what your door actually needs:

  • Diagnosis vs. replacement: sometimes the sensors just need realignment, not new parts
  • Single sensor vs. a pair: replacing both keeps the safety system balanced
  • Wiring condition: frayed or damaged sensor wiring adds to the job
  • Opener compatibility: older or specialty openers may need a compatible sensor upgrade

We'd rather inspect your door and give you an exact, upfront price than post a misleading range. Every quote includes a full safety test and a 1-year labor warranty, with no surprise charges. Most sensor jobs are completed same-day in Puyallup and Pierce County.

What We’ll Do

  1. Test the beam alignment with a diagnostic tool — not just by eye
  2. Inspect the wiring from sensor to opener for breaks or shorts
  3. Replace the sensor pair with OEM parts matched to your opener brand
  4. Re-secure mounting brackets so sensors stay aligned long-term
  5. Test the auto-reverse with a 2x4 block (required by federal safety standard)
