The gate is dead after a power interruption
After a power interruption, the gate does not respond at all — no movement, no lights on the control board, and the remote does nothing. The manual release still lets you open it by hand, but the automation is dead. Because it happened around a power cut, the fault is usually on the supply or protection side of the gate rather than in the motor or the remote.
Gates & Automation
A gate that cannot be opened or secured is treated as urgent.

What usually sits behind this symptom, and what tells one cause from another.
A tripped breaker or RCD feeding the gate
The gate is on a circuit that tripped during the interruption and has not been reset.
A surge that damaged the control board or its fuse
Power is reaching the gate but the control board shows no life, pointing at a blown fuse or a damaged board.
The gate losing its settings after the outage
Power is back and the board is lit, but the limits or remote memory need to be restored.
A damaged transformer or power supply inside the gate
The supply to the board is missing even though the circuit feeding the gate is live.
A fault to earth on the gate circuit holding the RCD off
The protective device trips again when it is reset, pointing at a fault on the gate side.
02BEFORE ANYONE VISITS
What you can safely check.
- Confirm the manual release works so you can always open the gate by hand.
- Check whether the breaker or RCD for the gate has tripped, without opening the board.
- Do not repeatedly reset a device that trips again — it is protecting against a fault.
- Note whether any other outdoor circuit is also dead, which points at a shared supply.
03WHAT WE MEASURE
We establish whether power is reaching the gate at all, then whether the board, its fuse and its settings have survived. A gate that is dead after an outage is usually a supply or protection problem, a blown fuse, or lost settings — all of which are found in order, starting from the circuit feeding the gate and working toward the board.
04IN A VILLA
A villa gate sits at the far end of the property on an outdoor circuit that is often grouped with the garden lighting and irrigation, and it takes the full brunt of a power interruption. A surge or a brief brown-out that the house shrugs off can be enough to trip the gate's protection or knock out its board, which is why the gate can be the only thing dead afterward.
05THE FIX
Which repair, and when.
A gate that is dead is not secure in the way the owner expects, and a fault that trips the protection should be found rather than held on. If the cause was a surge, the damage is usually contained to a fuse or a board, and leaving it only delays the same finding.
Reset the protection and verify the supply
The breaker or RCD feeding the gate has tripped and the circuit is sound.
Replace a blown fuse or a damaged board
Power is reaching the gate but the control side has been taken out.
Restore lost settings and re-pair remotes
The board is alive but the limits or remote memory were lost in the outage.
06WHAT DECIDES THE FIX
The same symptom can lead to different repairs. These are the things that decide which way it goes.
- Whether the breaker or RCD has tripped, which points at the supply or a fault.
- Whether power is reaching the gate but the board is dark, which points at a fuse or board.
- Whether the board is lit but the gate will not run, which points at lost settings.
- Whether the device trips again on reset, which means a fault rather than a one-off.
- Whether other outdoor circuits died too, which points at a shared supply or surge.
07HOW A VISIT GOES
What to expect when we come out, and why the order matters.
Confirm manual release
The manual release is checked so the gate can always be opened by hand.
Check the supply
The circuit feeding the gate and its protection are tested.
Check the gate board
The board, its fuse and its power supply are examined.
Restore or replace
Protection is reset, a fuse or board replaced, or settings restored as needed.
Cycle and confirm
The gate is run and the remotes re-checked to confirm it is fully back.
08KEEPING IT FROM RETURNING
Once it is fixed, these steps make the fault less likely to come back.
- Know where the manual release is and how to use it, so an outage is never a lockout.
- Keep the gate circuit identified at the board so it can be found quickly.
- If the gate dies after an outage, have the supply and protection checked rather than forcing it.
- Do not hold a tripping device on — it is protecting against a fault that needs finding.
- Consider surge protection on the gate supply if outages have damaged the board before.

Sensor alignment, remote programming and track clearing sit at the lower end. Capacitors, control boards and gearbox work sit higher. Full motor replacement is quoted separately after inspection.
10QUESTIONS
- Can I still open the gate if it is dead?
- Yes. Every automated gate has a manual release, usually a key-operated lever on the motor, so you can open it by hand even with no power. Knowing where it is turns an outage into an inconvenience, not a lockout.
- Why is only the gate dead?
- Because the gate is on its own outdoor circuit and takes the brunt of an interruption, so its breaker, fuse or board can be affected while the house carries on as normal.
- Should I reset the breaker myself?
- You can reset a breaker that has tripped once. If it trips again immediately, do not keep resetting it — that means there is a fault on the circuit and it should be found.
- Why will the remote not work even though the board is lit?
- The gate may have lost its settings or remote memory during the outage, so the remotes need re-pairing or the limits restoring before it will run.
- Was it damaged by a surge?
- It can be. A surge usually takes out a fuse or the control board, and power reaching the gate with a dark board is the typical sign of it.
- How do I know if it is the supply or the gate?
- By checking whether power is reaching the gate and whether the board is lit. No power points at the circuit; power with a dark board points at the gate itself.
- Is it safe to leave the gate dead overnight?
- You can still secure the gate manually, but the automation and any intercom release will not work, so it is worth having the supply and protection checked rather than leaving it.
- Will the settings need redoing?
- Sometimes. An outage can clear the travel limits or the remote memory, and they need restoring before the gate runs correctly and safely again.
- Why does the RCD trip again when I reset it?
- Because there is a fault to earth on the gate side — often moisture in a junction or a damaged cable. The device is doing its job, and the fault should be found.
- How can I stop this happening again?
- Know the manual release, keep the circuit identified, and if outages have taken the board out before, surge protection on the gate supply is worth considering.
