Morphy Richards oven overheats and burns food even at low temperature settings.

Safety first: Turn off power immediately if smoke or burning smell is present.

Steps:

• Check with thermometer: Use an oven thermometer to confirm that the oven is exceeding the set temperature.
• Inspect sensor: Test the oven temperature sensor resistance. Replace if it reads significantly lower than spec at room temperature.
• Mechanical thermostat: On knob-controlled models, the thermostat capillary bulb should be securely clipped inside the cavity. If damaged or dislodged, replace the oven thermostat.
• Control board: If the heating relay remains energised even when the set temperature is reached, the electronic control board may have a stuck relay and should be replaced.

Warning: Do not continue using an oven that overheats; this is a fire risk.
