Gas Interlock Repair & Emergency Call-Out
An interlock fault closes your gas and stops service. We diagnose the panel, proving circuit, valve and emergency stop, and carry the common failure parts on the van.
- Same-day attendance for kitchens with no gas
- Air pressure switches, solenoid valves and replacement panels in stock
- Root-cause diagnosis — we never bridge out a safety circuit to get you trading
Symptoms we fix
| Symptom | Usual cause |
|---|---|
| No gas at all, panel dead | Supply fuse, isolator switched off, failed panel PSU |
| Interlock keeps tripping mid-service | Blocked filters or slipping belt reducing extract, pressure switch set too tight |
| Won't prove ventilation with fan running | Pressure switch tubing blocked, reversed or split; failed switch; duct sensor fouled with grease |
| Panel healthy but no gas | Solenoid coil failed open circuit, valve stuck closed, valve wired to wrong output |
| Buzzing solenoid valve | Low voltage at the coil, debris in the seat, failing coil |
| Trips on start-up only | Fan run-up time shorter than the proving delay, or e-stop latched |
Before you call out
- Check every emergency stop button is reset — a latched e-stop mimics a system failure
- Confirm the extract fan is actually running and the isolator is on
- Check canopy filters are in place and not blocked
- Note any panel indicator lights or fault codes before resetting
Smell gas?
Do not use the interlock or any electrical switch. Turn off the gas at the emergency control valve, ventilate, evacuate and call the National Gas Emergency Service on 0800 111 999, then call us.
Frequently asked questions
Can you attend today?
We run a 24/7 UK response desk and prioritise kitchens that are down. Call and we will give you a realistic arrival window.
My interlock trips every lunchtime — is it faulty?
Usually it is genuine: at peak load the extract cannot maintain pressure, often because of blocked filters or a fouled duct. The interlock is doing its job. We measure it and correct the cause.
Is it cheaper to repair or replace?
Sensors, coils, valves and e-stops are worth repairing. Obsolete panels with no spare parts are better replaced with a current equivalent.
