When the gate motor fails and you are already home
5 min read · written for Fourways
A gate that will not move is one of the more frustrating failures because it is usually not the thing you assume. Often the motor is the only part still working properly, and what has actually failed is somewhere else entirely.
What usually goes first
The battery. Most sliding gate motors run off a battery that the mains keeps topped up, and that battery has a service life measured in a few years. It degrades quietly, works fine on a full charge, and then fails to lift the gate the first time the power has been off for a while.
This is why gate failures cluster around power interruptions. The outage did not break anything — it revealed a battery that had been dying for months.
The track, the wheels and the obstruction
A sliding gate that hesitates, judders or stops partway is often fighting its own track. Dust and stones build up, wheels wear flat on one side, and the motor's safety cut-out does exactly what it is designed to do.
Before assuming anything electrical, look at the track. If you can push the gate by hand with the motor released and it feels heavy or gritty, the motor is not your problem.
Remotes and receivers
If the gate works from the keypad or the intercom but not from a remote, the fault is in the remote or the receiver rather than the motor. Remote batteries are cheap and are worth eliminating first.
If several remotes have stopped at once, that points at the receiver instead, which is a different repair.
The manual release, and its limits
Every motor has a manual release so the gate can be moved by hand when the motor cannot move it. Find yours and learn how it works before you need it — usually a key or a lever on the motor housing.
It gets you in and out. It does not secure the gate, and a gate on manual release can generally be pushed open by anyone. It is a way through, not a solution to leave in place.
Where the locks come in
Pedestrian gates alongside a driveway gate are frequently the neglected item on a property. They live outdoors, take dust and rain, and seize because nobody uses them daily.
Once one seizes, the instinctive response is force, which bends the keeper and converts a clean-and-adjust into a replacement. If a pedestrian gate lock has started to stick, deal with it while it is still a service rather than a part.
What to check before calling
Does it work on mains but not after an outage? Battery. Does it judder or stop partway? Track or wheels. Does it work from the keypad but not the remote? Remote or receiver. Is the gate heavy to move by hand on manual release? Mechanical, not electrical.
Any of those answers makes the callout shorter and the quote more accurate, and a couple of them you may be able to resolve yourself.
