Why Has My Oven Grill Stopped Working?
The oven grill uses a separate heating element from the main oven element, controlled by its own circuit within the selector switch. When it stops working, the fault is usually in one of three places: the grill element itself, the selector switch, or the wiring between them.
If the rest of the oven works normally (main heat function, fan, light) but the grill does not activate, this narrows the fault considerably and makes diagnosis straightforward for an experienced engineer.
Most Common Causes of a Failed Oven Grill
- Blown grill element: The grill element burns out over time — especially if it is frequently used at maximum temperature. It may show a visible break or burn mark.
- Faulty selector switch: The rotary switch that selects between oven functions can fail in individual positions. The grill position stops making contact while other settings still work.
- Wiring fault: Wires to the element or switch can burn through, particularly near the element where temperatures are highest.
- Blown thermal limiter: Some ovens have a thermal cutout that trips if the grill overheats. This can fail permanently and cut power to the grill circuit.
Repair Costs for a Faulty Oven Grill
| Fault | Typical cost (parts & labour) |
|---|---|
| Grill element replacement | £70 – £130 |
| Selector switch replacement | £80 – £150 |
| Thermal limiter replacement | £60 – £110 |
| Wiring repair | £60 – £120 |
Can I Replace a Grill Element Myself?
Grill elements on many ovens are accessible from inside the oven cavity and are held in by two screws plus two spade connectors. Some confident DIYers do replace these themselves. However, if the fault is in the selector switch or wiring, the oven needs to be pulled out and the back panel removed — a job best left to a qualified engineer. Always isolate the power before any electrical work.
Is It Worth Repairing?
Yes, in almost all cases. A grill repair typically costs £70 to £150 — a fraction of the cost of a replacement oven. Even if both the element and the switch have failed, the combined repair cost is usually still well below the price of a new appliance.
