Why Is My Oven Overheating?
An oven that burns food, overshoots temperature, or keeps heating far beyond the setting often points to a thermostat problem, temperature sensor issue on electronic models, or a control fault.

Before you order, use Confirmed Fit
For advice and repair topics like this one, the biggest buying mistake is ordering on appearance alone. Search by the exact model number wherever possible, because small appliance revisions can use different seals, filters, motors, pumps, lamps, shelves, or trims.

At a Glance
- Overheating is usually a control problem rather than an element problem.
- The oven may still heat normally at first, but then fail to cycle off correctly.
- Estimated time: 30-90 minutes depending on model and access.
Safety First
Disconnect the appliance from the mains before removing panels or testing controls. Stop using the appliance if insulation, wiring, or nearby cabinetry is showing signs of heat damage.
Common Causes
- Failed thermostat stuck closed
- Faulty temperature sensor on electronically controlled ovens
- Selector or relay fault keeping the element energised
- Incorrect calibration after previous repair
- Poor door seal causing unstable temperature readings and excessive run time
Quick Checks First
- Check whether food is burning on all shelves or just one area.
- Use an oven thermometer to compare the displayed or selected temperature with actual cavity temperature.
- Inspect the door seal for damage that may cause uneven cooking or heat loss.
- Look for signs that the thermostat light never cycles off.
Diagnosis and Fix by Cause
Thermostat fault
- On many traditional ovens, a faulty thermostat is the main cause of overheating.
- If the thermostat does not open when the cavity reaches temperature, the element can keep heating.
Sensor or electronic control issue
- Many newer ovens use a sensor and electronic control rather than a purely mechanical thermostat.
- If the sensor is inaccurate or open circuit, the control may misread the cavity temperature.
Door seal and airflow issue
- A damaged seal usually causes heat loss rather than true overheating, but it can still distort cooking performance and make diagnosis harder.
FAQ
Why Is My Oven Overheating?
An oven that burns food, overshoots temperature, or keeps heating far beyond the setting often points to a thermostat problem, temperature sensor issue on electronic models, or a control fault.
How do I get a Confirmed Fit oven & cooker spare part for this fault?
Use the full model number exactly as shown on the rating plate. When Spares2Repair matches that model to a compatible part we call it Confirmed Fit. Similar-looking parts can differ across revisions, production runs, and variants, so model matching is the safest route before ordering.
When should I stop and get professional help?
Stop and seek qualified help if the work involves unsafe live electrics, sealed systems, gas-related risks, or damage that goes beyond straightforward model-matched part replacement.
