Morphy Richards oven temperature fluctuates widely; sometimes too hot, sometimes too cool during the same cook.

Safety first: Disconnect power before accessing internal components.

Steps:

• Check sensor wiring: Inspect and reseat the temperature sensor connector on the control board.
• Thermostat contacts: On mechanical thermostat models, inspect the thermostat for pitting or burning; replace the oven thermostat if contacts are worn.
• Control board: Listen for rapid clicking of relays during operation; if present, the electronic control board may be faulty.
• Ventilation: Ensure cabinet vents are not blocked, as overheating can affect control stability.
