The short answer
Stop and isolate the oven for any smell of gas, any scorching or burning smell, a breaker that trips, a damaged cable, or an oven that stays live when switched off. Gas smell means leave the building and call the emergency number from outside. Everything beyond cleaning belongs to a registered engineer.
What you observe
- A smell of gas anywhere near the oven — Evacuate and call from outside. Nothing else on this page matters first.
- A scorching or hot insulation smell — An electrical fault. Isolate and stop using it.
- The breaker trips when the oven is switched on — A fault or a circuit carrying too much.
- A damaged, cut or heat-scorched cable — Common where equipment is moved for cleaning.
- NEAR MISS - a click and a fan starting when heat is called for — Normal ignition and fan behaviour.
Causes, most likely first on this brand
- A gas leak or a fault on the gas train — First in importance regardless of likelihood. It is the one hazard where the correct action is to leave rather than to investigate.
- Water ingress from cleaning — Second, and very common on catering lines. Hosing or heavy washing around a gas oven puts water into control enclosures and ignition components, which then trip breakers or fail intermittently.
- A damaged supply cable — Third. Ovens are dragged out for cleaning and pushed back, and a cable crushed behind a leg or scorched against a hot surface is a real fire and shock risk.
- Grease build-up around electrical and ignition parts — Fourth. Grease is fuel, and grease around an ignition system or a hot control compartment is exactly where a kitchen fire starts.
- A worn ignition, control or wiring fault — Last. Not kitchen work, and the reason the enclosure stays closed.
Check in this order, and why
- Treat any gas smell as an evacuation, not a diagnosis — Leave, then call from outside.
- Isolate at the first burning smell or trip — Nothing here is worth a second attempt.
- Inspect the cable along its whole run — Crushing behind a leg is easy to miss and easy to find.
- Look for water and grease where they should not be — Both are cleaning-related causes with cleaning-related fixes.
What an owner can safely check
- Evacuate and call from outside for any gas smell — Do not touch a switch and do not use a light.
About 5 min
- Isolate the oven at its breaker and its gas valve — Do this before any inspection or cleaning.
About 10 min
- Inspect the supply cable end to end — Look for crushing, cuts and heat damage where it passes hot surfaces.
Tools: torchAbout 15 min
- Degrease around the oven without hosing it — Use cloths and degreaser; never direct water at a control enclosure.
Tools: degreaser, clothAbout 45 min
- STOP HERE at any enclosure, ignition or gas component — That is registered gas and electrical work.
Before you open anything
Safety
If you smell gas, do not touch any switch, do not use a light, leave the building and call the gas emergency number from outside. Never hose or pressure-wash a gas oven or the area around its controls. Never bypass a cut-out, open an electrical enclosure or work on a gas train. Isolate at both the breaker and the gas valve before cleaning, and do not reset a tripping breaker repeatedly to get through a service.
When to call a technician
Call the gas emergency number, from outside the building, for any smell of gas. Call a registered gas engineer for a burning smell, a breaker that trips with the oven alone, a damaged cable, scorching anywhere on the machine, or an oven that behaves differently after a deep clean. Do not keep resetting the breaker to finish service, because that makes an electrical fault worse.

What this page does not cover
This page covers the Brigade commercial gas convection ovens and stops where registered work begins. Electric ovens have no gas hazard and a different boundary. Not included by design: gas pressures, component identification, circuit ratings, leak-test procedures and commissioning data, all of which require instruments and a registered engineer.
