Display shows E05 and oven stops heating shortly after start

Safety first: Turn off power at the breaker and allow the oven to cool.

• Inspect sensor and wiring: Remove the sensor from the cavity and check for signs of moisture, corrosion, or damage. Inspect the cable for crushed insulation or contact with sharp metal edges.
• Measure resistance: At room temperature, measure the sensor resistance. A very low reading (near 0 Ω) indicates a shorted sensor. Replace with a genuine or compatible Essentials sensor.
• Check for shorts to earth: With one meter lead on the sensor wire and the other on the oven chassis, ensure there is no continuity. If there is, locate and repair the insulation fault.
• Examine control board: If sensor and wiring test good, the input circuit on the control board may be damaged. Inspect for burned components near the sensor connector. Replace the control module if necessary.
• Reassemble and test: After repairs, restore power and run a preheat cycle. Confirm that E05 does not reappear and that temperature is stable.
