Federally-mandated garage door safety sensors (the two little eyes 6 inches off the floor) are also the #1 reason a door won't close. When one LED is off or blinking, the opener refuses to close as a safety feature.
We diagnose, re-align, re-wire, and replace LiftMaster, Chamberlain, Genie, Sommer and Marantec photo-eye sensors across Chattanooga the same day.
**Both LEDs solid** = sensors are aligned and clear. Problem is elsewhere.
**Sending sensor (amber) solid, receiving sensor (green) off/blinking** = misalignment, dirty lens, or wiring fault. Re-aim until green goes solid.
**Both LEDs off** = no power to the sensors. Tripped breaker, cut wire, or a wire pulled out of the staple. We trace and re-terminate.
**Both LEDs blink in sync with the opener** = stuck wall-button on a multi-function control panel.
Lawn equipment cuts the bell wire stapled along the wall. Lawn mower or car bumper bumps the bracket. Sun glare through an open garage door blinds the receiving eye in late afternoon. Spider webs cover the lens (yes, really—our most common service call). Wires corrode where they were stapled through to a damp wall.
