Safety Photo-Eye Sensor Alignment & Wiring in Richmond, CA
Federal safety standard UL 325 mandates that all residential garage door openers must feature an active optical safety reversal system. When infrared sensors become misaligned, bumped by trash cans, or suffer chewed low-voltage wiring, your garage door will refuse to close automatically. Siân Garage Door Repairs diagnoses and fixes sensor issues across Richmond.
⚠️ Common Symptoms & Failure Indicators
Door Starts Down, Then Reverses and Blinks Lights
The opener detects a beam interruption, immediately reversing the door to the fully open position.
Must Hold Wall Button Continuously to Close Door
Holding the interior wall button overrides safety sensors in an emergency, confirming optical sensor failure.
Flickering or Dead LED on Sensor Eyes
The sending (amber) or receiving (green) LED indicator is unlit, dim, or flickering intermittently.
Sunlight Blinding Sensor Optics
Low-angle morning or evening California sunlight shining directly into the receiving lens blinds the sensor.

Richmond Micro-Climate & Hardware Engineering

💬 Frequently Asked Questions in Richmond, CA
Why is my garage door opener light clicking and flashing 10 times?
Ten flashes indicate that the infrared safety sensors are out of alignment, obstructed, or disconnected.
How high off the floor should safety sensors be mounted?
According to federal UL 325 safety standards, photo-eye sensors must be mounted no higher than 6 inches above the garage floor.
Can dirt or spider webs cause safety sensors to fail?
Yes! Dust, cobwebs, and bugs on the small glass lens can scatter the infrared beam and cause erratic door reversals.

Yes, our technicians carry low-voltage copper wiring and splice, solder, and neatly route new wiring to the motor.
