Blocked Safety Sensors

Safety sensors that are misaligned, dirty, or obstructed will prevent the gate from closing, leaving it stuck open as a safety precaution.

Physical Obstruction or Damage

Debris, a shifted post, overgrown vegetation, or physical damage to the gate or track can prevent the gate from traveling to the closed position.

Failed Auto-Close Feature

If the auto-close timer or relay on the control board has failed, the gate may open normally but never automatically close.

Limit Switch Problem

A faulty or miscalibrated close limit switch may prevent the operator from initiating the close cycle.

Mechanical Binding

Worn hinges, a bent gate frame, or a derailed slide gate can cause the gate to bind in the open position.

Manual Release Left Engaged

If the manual release was used during a power outage and not properly re-engaged, the gate may stay open and not respond to the operator.

Control Board Failure

A failing control board may execute the open command but fail to complete the close sequence.
