Faulty Safety Sensors Preventing Your Gate from Closing? We'll Fix It.
Gate safety sensors are required by UL 325 safety standards to prevent automatic gates from closing on people, vehicles, or animals. When they malfunction, they can prevent your gate from closing at all — or worse, fail to detect a real obstruction. Access Pro Gate Company repairs and replaces gate safety sensors throughout Willis, The Woodlands, Conroe, and Montgomery County, TX.
Signs You're Experiencing This Problem
- Gate reverses every time it tries to close
- Gate won't close and the sensor fault light is on
- Gate closes fine in some conditions but reverses in others
- Gate reverses when a vehicle approaches from outside
- Sensor indicator lights are off, blinking, or showing red
- Gate was working until sensors were bumped or moved
- Gate reverses in bright sunlight or after rain
Common Causes
Sensor Misalignment
Photoelectric safety sensors must be precisely aimed at each other. Ground movement, physical bumps, or post shifts can misalign them, breaking the beam and triggering a fault.
Dirty Sensor Lenses
Dust, spider webs, pollen, and moisture on the sensor lenses scatter the beam and cause false obstruction detections.
Sun Glare
Direct sunlight hitting a sensor lens can overwhelm the photoelectric receiver, causing it to falsely detect an obstruction. Most common in morning and evening.
Sensor Wiring Damage
The low-voltage wiring to the sensors can be cut, corroded, or damaged by pests, causing the sensor circuit to show a fault.
Failed Sensor Unit
Sensors can fail internally due to moisture intrusion, age, or electrical damage. A failed sensor typically shows a permanent fault condition.
Reflective Surfaces
Shiny surfaces near the sensor — wet pavement, chrome bumpers, or reflective tape — can bounce the sensor beam back and trigger a false detection.
Incorrect Sensor Height
Sensors mounted at the wrong height may not detect vehicles properly, or may be triggered by ground-level objects.

Frequently Asked Questions
Are gate safety sensors required by law?
UL 325 safety standards require entrapment protection devices — including safety sensors — on automatic gate operators. Properly functioning sensors are both a safety requirement and a liability protection.
My gate reverses every time it tries to close — is it definitely the sensors?
Sensor issues are the most common cause of gates that reverse before closing, but limit switch problems and mechanical binding can also cause this. We'll diagnose the exact cause.
Can I clean my safety sensors myself?
Yes — gently wipe the lenses with a clean, dry cloth. If cleaning doesn't resolve the issue, the sensors may need professional realignment or replacement.
How do I know if my safety sensors are aligned?
Most sensors have indicator lights — solid green typically means aligned and communicating, while blinking or red indicates a fault. Check your operator's manual for your specific indicator pattern.
Do I need to replace both sensors if only one is faulty?
Not always. We can often replace just the failed sensor. However, if both sensors are old or mismatched, replacing the pair ensures consistent performance and proper safety function.
