Is a Burning Smell From Your Oven Normal?
Not all burning smells indicate a fault. Brand new ovens often produce a chemical or burning smell for the first few uses as manufacturing oils and coatings burn off — this is normal and usually resolves after 2 to 3 uses. Ovens that have not been used for a while or have significant grease buildup will also produce a burning smell when first switched on.
However, certain types of burning smell indicate a genuine problem that requires an engineer.
Harmless Causes of a Burning Smell
- Grease or food debris on the oven floor, elements, or cavity walls burning off
- A new oven burning off factory coatings (first 2–3 uses)
- Food spillage that has dripped onto the element or oven base
- Dirty or grease-coated fan at the back of the oven
If your oven smells of burning but works normally and the smell reduces over a few uses, a deep clean is usually all that is needed.
When a Burning Smell Means a Genuine Fault
- Plastic or electrical burning smell: This suggests wiring insulation is burning. Switch the oven off at the wall immediately and do not use it until an engineer has inspected it.
- Burning smell that does not improve: If the smell persists after cleaning, it may indicate a failing element that is arcing or a motor that is burning out.
- Smoke coming from the back panel or controls: Stop using the oven. This can indicate a wiring fault or overheating component.
- Burning smell with reduced heat output: A failing element can produce a burning smell as it partially fails before going completely.
What to Do
| Symptom | Action |
|---|---|
| Burning food/grease smell, oven works normally | Deep clean the oven cavity and elements |
| Electrical or plastic burning smell | Switch off at wall, call engineer |
| Burning smell with smoke from back or controls | Switch off at wall, call engineer urgently |
| Persistent burning smell after cleaning | Book an engineer to inspect |
Typical Repair Costs
If an engineer finds a failing element, the repair typically costs £80 to £140. A wiring fault costs £60 to £150 depending on severity. A diagnostic visit where the engineer identifies and confirms the fault typically costs £40 to £80, which is often offset against the repair cost if you proceed.
