Garage Door Safety Sensor Repair in Phoenix
If your garage door will not close, reverses immediately, or closes and then opens back up, the safety sensors are one of the first things to check. Great Doors and Gates diagnoses and repairs garage door safety sensor issues across the Phoenix metro area, including alignment, wiring, replacement, and full safety verification.
Upfront Pricing, Safety-First Work
We diagnose the root cause, explain your options, and verify safe operation before we leave.
Common Sensor Problems
- Sensors are misaligned (bumped, shifted, loose brackets)
- Dirty lenses or sun glare interference
- Damaged wiring or loose connections
- Faulty sensor units
- Track or door movement causing alignment to drift
Because sensors are part of the safety system, we treat these issues as high priority.
What We Do
We can:
- Align sensors and secure mounting brackets
- Repair wiring or replace damaged connectors
- Replace failed sensor units when needed
- Verify opener limits/force settings and safe operation
- Confirm auto-reverse and obstruction response
If the door is binding or out of alignment, sensors can be a symptom rather than the root cause. We will look for the underlying mechanical issue too.
Frequently Asked Questions
My door starts closing then goes back up. Is it always sensors? Not always. Sensors are common, but obstructions, track issues, or opener settings can also cause reversing. We test the whole system.
Can I bypass the sensors? We do not recommend bypassing safety devices. It creates a serious safety risk.
