Blinking Sensor Lights
Usually caused by misalignment, dirty lenses, loose brackets, or wiring issues.
Sensor Testing & Alignment
Garage Door Safety Sensor Service
Valiant Garage Door handles garage door safety sensor problems that cause doors to reverse, refuse to close, blink at the opener head, or fail the auto-reverse safety test.
Common Safety Sensor Problems
Door Will Not Close
When the beam is interrupted or the sensor circuit is failing, the opener may stop or reverse immediately.
Intermittent Closing
Sunlight, vibration, damaged wires, or loose fasteners can create random failures that need a real inspection.
What We Check
- Sensor alignment and mounting brackets
- Lens cleaning and obstruction checks
- Wire condition at the opener head and jamb
- Auto-reverse function and full closing cycle
- Related opener logic if the issue is not sensor-only
