Garage Door Sensor Yellow Light — Won't Close? Covington Repair
A yellow or flashing sensor light means the photo eyes can't communicate — and the door won't close for safety. We realign, clean, or replace the sensors.
Sensor Repair in Covington, LA
Garage door photo-eye sensors are a required safety feature that prevents the door from closing on a person, pet, or object. When the sensor LED is yellow, flashing, or off, it means the two sensors can't see each other — and the opener refuses to close the door. The fix is usually a simple realignment, but it can also be a wiring issue, a failed sensor, or a logic board problem.
The most common cause of a sensor yellow light is misalignment. The sending sensor (with the amber LED) and the receiving sensor (with the green LED) must point directly at each other. If one gets bumped — by a trash can, a broom handle, or vibration — the beam breaks and the door won't close. We realign both sensors, clean the lenses, and verify the beam is solid.
If realignment doesn't fix it, we test the sensor wiring (mice and weed trimmers can damage the low-voltage wire), the sensor units themselves (they can fail from moisture or age), and the opener logic board (which processes the sensor signal). We carry replacement LiftMaster, Chamberlain, and Genie sensors on every truck.
Common Symptoms We See in Covington
If you recognize any of these signs, call before the problem turns into a bigger, more expensive repair.
Yellow light on one sensor
The sending sensor has an amber/yellow LED that should be steady. If it's blinking or off, the beam is broken and the door won't close.
Door starts down then reverses
The opener begins closing, the sensors don't detect the beam, and the door reverses back up. This is the safety system working as designed.
Green light is off on receiving sensor
The receiving sensor's green LED should be steady when aligned. If it's off, the sensors aren't communicating — could be alignment, wiring, or a failed sensor.
Door closes with button held but not on its own
If you have to hold the wall button to close the door, the sensors are failing. Holding the button overrides the sensor safety circuit.
