When safety sensors malfunction, your door may refuse to close.
Garage door repair in San Diego starts with a $125 service call that's applied toward the work. Castle has served San Diego to Riverside County since 1981 — family-owned, CSLB #1154002.
Since 1993, federal law has required all garage doors to have safety reversing sensors — the small photo-eye sensors mounted near the floor on each side of the door opening. These sensors detect objects in the door’s path and prevent it from closing, protecting children, pets, and property.
When these sensors malfunction, the most common symptom is a door that starts to close, reverses back up, and flashes the opener light. It’s one of the most frequent calls we receive, and it’s usually a straightforward fix.
You can try these steps yourself before calling a technician: Clean the sensor lenses with a soft cloth. Check that the small LED lights on each sensor are lit (green for the sending eye, amber for the receiving eye on most models). Make sure nothing is blocking the path between the sensors. If these steps don’t resolve the issue, give us a call.
We provide upfront pricing before any work begins. No surprises, no hidden fees. Every job includes a detailed written estimate so you know exactly what you’re paying for.
Every repair is backed by our 1-year parts-and-labor warranty — if the same problem comes back, we come back, with no second service call fee.
