Garage Door Sensor Repair in Arlington, TX
Garage door safety sensors are the two small units mounted near the floor on each side of the door opening. When one stops working, the door reverses immediately or won't close at all. The problem is usually a wiring fault, a damaged sensor unit, or moisture that's gotten into the housing. Ignoring a broken sensor means either the door won't function or, worse, it closes when it shouldn't.

When to Call
When You Need Garage Door Sensor Repair

How It Works
Our Process for Garage Door Sensor Repair
- 1
Read the Opener Code
The number of blinks on the opener light tells us which sensor is at fault before we touch anything.
- 2
Check Wiring and Connections
We trace the wire from the sensor to the opener, looking for cuts, pinches, or corroded terminal connections.
- 3
Test or Replace the Sensor
If the wire is intact but the unit itself has failed, we swap in a matching replacement sensor and rewire it properly.
- 4
Verify Safety Function
We pass a physical object through the beam while closing the door to confirm the sensor stops it correctly.
Arlington Context
Why this matters in Arlington
Arlington's heavy spring storm season brings water into garages through gaps around the door, and that moisture is the number one cause of sensor failure we see here. Sensors mounted low to the concrete floor take the most exposure.
Straight Talk
About pricing & scope
Cost depends on whether it's a wiring fix or a full sensor replacement and whether your opener model uses a proprietary sensor that costs more than a universal unit. We'll tell you which situation you're in before doing any work.
