Oven overheats, may scorch food, and displays E02 or shuts down mid-cycle.

Safety first: Turn off power at the breaker and allow the oven to cool completely. Overheating can damage internal wiring and insulation.

Inspection steps:

• Check that the oven vents (front trim, rear, and under the control panel) are not blocked by foil, panels, or cabinetry modifications.
• Inspect the temperature sensor inside the cavity for signs of damage, deformation, or burnt insulation.
• Remove and test the sensor with a multimeter; compare its resistance to the specification at room temperature and at a moderate heat (if you have a heat source and can test safely).
• If the sensor reads significantly out of specification or fluctuates when gently tapped, replace it.
• Inspect the cooling fan (if fitted) behind the control panel: spin the blades by hand with power off; they should move freely. If seized or noisy, replace the cooling fan motor.
• If the sensor and fan are good, the main control board may be misreading the temperature and require replacement.

After repair: Run the oven at 180°C and monitor temperature stability and error codes.
