Gate motor not working?

Six common faults, what usually causes them and what you can safely check before calling an installer.

Common faults

Check these first.

The remote does nothing.Change the remote battery first. If the gate still ignores it, the remote may need to be learned again on the control board; the manual shows the button sequence. Check that the board has power: its LED should be lit.

The gate stops or reverses by itself.Usually the photocells: something blocks the beam, the lenses are dirty or the two units have moved out of line. Clean and realign them. If it reverses part-way with nothing in the way, the force setting may be too low for summer, or the gate has started to stick.

The motor hums but the gate does not move.Check that the manual release is locked back in drive. On a sliding gate, check that the rack still meets the pinion. A hum with no movement can also mean a failed capacitor on AC motors: call your installer.

The gate does not stop at the end.The limit switch is not being triggered: on AGL sliding motors, check that the magnets on the rack are still in place and at the right distance from the motor.

It works in the morning, then stops in the afternoon.The thermal protection is cutting the motor to stop it overheating. Let it cool. If it happens often, the motor is working too hard for the gate or the traffic: check the gate moves freely, or move to a model rated for more cycles an hour.

Nothing works after a power cut.Check the breaker, then use the manual release to open the gate. A UPS keeps the gate working through power cuts.

Stay safe

Before you touch the gate.

Switch off the breaker before opening the motor cover or touching the board.
Use the manual release key to move the gate by hand; never force it against the motor.
Do not bypass the photocells: they stop the gate closing on a car or a person.

Manuals and wiring diagrams are in the Trade centre, and spare boards, remotes and photocells are listed under spare parts.

Troubleshooting FAQ

The remote does nothing

Change the remote battery first. If the gate still ignores it, the remote may need to be learned again on the control board; the manual shows the button sequence. Check that the board has power: its LED should be lit.

The gate stops or reverses by itself

Check that the manual release is locked back in drive. On a sliding gate, check that the rack still meets the pinion. A hum with no movement can also mean a failed capacitor on AC motors: call your installer.

The gate does not stop at the end

The limit switch is not being triggered: on AGL sliding motors, check that the magnets on the rack are still in place and at the right distance from the motor.
