Sensor Alignment
Your photo-eye sensors are the law — they have to work or your door won't close. We align them properly.
02What you get
Federal law requires every modern garage door opener to have working photo-eye sensors at the bottom of the tracks. When they're misaligned, your door reverses on close, blinks an error code, or refuses to operate. We re-align, replace damaged sensors, and verify the safety reverse before we leave.

- 02Wiring inspection and re-termination
- 03Sensor replacement (LiftMaster, Chamberlain, Genie)

03When you need this
Signs to call us.
- Door reverses immediately on close (one sensor sees an obstruction)
- Opener LEDs blink an error code referencing photo-eye or safety reverse
- Sensor LEDs not lit, or one green and one red
- Sensor knocked physically out of alignment by a bike, broom, or lawnmower
04What we see
Common failure
modes.
01
Sensor bracket bent
Most common cause. We straighten or replace the bracket and re-align in minutes.
02
Wire chewed by rodents or pulled loose
Garage sensor wiring runs at floor level — vulnerable. We re-terminate or rerun the wire.
03
Sun glare hitting the receiver lens
South- and west-facing doors at certain hours of the day. We shade-bracket the receiver.
