Why your Unox combi oven is not heating
When a Unox combi oven is not heating, here's what you'll usually notice: appliance runs but doesn't reach set temperature. Failed heating element, igniter, or thermal fuse. Nine times out of ten it comes down to failed igniter or gas valve. Left unaddressed, the kitchen loses a station it can't work around.
Most likely causes
- Burned-out heating element
- Tripped thermal fuse
- Faulty temperature sensor
- A bad control board
Known Unox combi oven weak points
- Limescale scaling in steam/spray system in hard water
- Fan motor bearing wear
- Door gasket wear
- Touchscreen or control board faults
Quick check — and when it's not DIY
There's one thing worth checking before you book anyone: check whether an ignition click or spark is audible at all when it should be heating. When that isn't the fix, no spark or flame usually means the igniter or gas valve itself has failed, and gas-carrying parts are restricted to licensed work in most jurisdictions.
