Appliance type Oven
Risk level Medium
Typical repair cost £15–£150 depending on whether recalibration, thermostat or sensor replacement is needed.

Checks you can try yourself

  1. Use an inexpensive oven thermometer to compare the set temperature with the actual internal temperature.
  2. Try reducing the set temperature by 10–20°C and see if cooking times match recipe expectations more closely.
  3. Make sure shelves are in the recommended positions and that trays do not sit directly on the oven base unless specified.
  4. Avoid using dark, thin trays on fan‑assisted modes, as these can brown food faster.

Always unplug the appliance and switch off the power at the mains before accessing internal parts, and do not work on gas appliances yourself.

Advanced checks

  • A faulty thermostat or temperature sensor can cause the oven to overshoot the target temperature.
  • On some models you can recalibrate the thermostat through the control panel—check the user manual.
  • Uneven cooking can also result from failed elements where only the grill or one side of the oven heats properly.

How to prevent this problem

  • Use an oven thermometer occasionally to confirm the set temperature is accurate.
  • Place trays in the recommended shelf positions and avoid pushing them right against the back wall.
  • Keep the door glass clean so you can see food browning without constantly opening the door.

When to call a professional

If the oven temperature is significantly higher than the set point, or elements do not appear to heat evenly, an engineer can test sensors, thermostats and elements and replace faulty parts.
