Tracing a Gate Fault From the Supply Outward
An electric gate is a small electrical system that happens to move a piece of steel. When it goes quiet, the cause sits somewhere along a chain: the supply, the transformer, the fuses, the control board, the wiring to each device, and then the devices themselves. Guessing at any link wastes money, so we test in order.
This page owns that chain. If the leaf sags, drags or sticks, our automatic gate repair page covers the steel and the hinges. If the motor, gearbox or arm is the failing part, our gate opener repair page covers the drive unit. We come to this page's work when the machinery may be sound and something upstream of it is not.
The first visit follows a fixed order:
- confirm there is supply at the gate, and that the breaker feeding it has not tripped
- measure the low-voltage output of the transformer
- check the fuses and any surge protection on the supply
- look over the control board for scorched parts, moisture and burnt contacts
- test the wiring to each sensor, keypad and receiver
Only after that do we say which link failed, so that the quote covers a diagnosed fault and not a hopeful swap.
