What sensors actually do

Photo-eye safety sensors transmit an infrared beam across the door opening. If anything breaks the beam, the door reverses. Required by federal UL 325 since 1993.

5 reasons sensors fail (in order)

1. Knocked out of alignment by a car bumper. 2. Spider webs or dust on the lens. 3. Wiring nicked by a roller. 4. LED bulb burned out. 5. Actual sensor failure.

Quick at-home test

Look at both sensor LEDs. Both solid (green or amber) = working. One off or blinking = misaligned. Both off = power or wiring issue.
