Electrical or Sensor Failures in Automatic Gates

When your automatic gate stops responding, opens on its own, or refuses to close, it’s often due to an electrical malfunction or faulty safety sensors. These are some of the most common issues homeowners face with powered gates, and at A.S. Gate and Fence, we know exactly how to diagnose and repair them.

Your gate’s electrical system is the heart of its operation. From the control board and wiring to the photo sensors and loop detectors, every part must work together seamlessly. When one component fails, your gate’s safety and reliability are compromised.

Common Electrical and Sensor Problems We Repair

  1. Wiring Damage or Short Circuits
    Over time, moisture, insects, or rodents can damage your gate’s wiring, leading to short circuits or intermittent power loss. We inspect and replace damaged cables to restore a steady power flow.

  2. Faulty Control Boards
    The control board acts as the “brain” of your automatic gate. Power surges or lightning strikes can burn circuits and cause your gate to stop working entirely. We repair or replace circuit boards and reprogram the system to manufacturer standards.

  3. Sensor Misalignment
    If your gate won’t close fully or keeps reversing, the photo eyes (safety sensors) might be dirty or out of alignment. We clean, realign, and recalibrate sensors so your gate detects obstacles correctly and operates safely.

  4. Power Supply Issues
    A tripped breaker, blown fuse, or damaged transformer can cut power to your gate opener. We test your power connections and ensure your system is safely grounded.

  5. Loop Detector Malfunctions
    Vehicle detection loops under your driveway may fail due to damage or corrosion. We replace loop wires and recalibrate your detector to ensure reliable gate response.

  6. Interference or Communication Errors
    Sometimes, nearby electronic devices or worn-out receiver components can disrupt signals between your remote, keypad, and control unit. We diagnose and fix communication issues for smooth operation.
