Display shows temperature sensor fault; oven may not start or stops shortly after starting.

Safety first: Turn off power at the breaker before accessing internal components.

• Access the sensor: Locate the temperature sensor probe inside the oven cavity. Remove the mounting screws and gently pull the sensor into the cavity to access the connector.
• Measure resistance: Disconnect the sensor and measure resistance at room temperature. Compare to Miele specifications (commonly around 1–1.5 kΩ at 20–25°C). If reading is near 0 Ω (short) or infinite (open), replace the sensor.
• Check wiring to control: If the sensor tests good, trace the harness to the electronic control module. Inspect for damage, especially at pass-through grommets. Repair or replace damaged wiring.
• Control board diagnosis: If sensor and wiring are correct, the control's sensor input circuit may be defective. Replacement of the control module is required.

Clear the error by disconnecting power for a few minutes after repair, then test the oven in a low-temperature mode.
