Microwave shows E15 and may stop mid-cycle; sometimes accompanied by a faint burning smell from the cavity.

Safety first: Unplug the microwave and allow it to cool before inspection.

Step-by-step checks:

• 1. Visual cavity inspection: Look for burned spots, peeling paint, or arcing marks that might have overheated the sensor area.
• 2. Access the sensor: Remove the cabinet and locate the cavity thermistor or temperature sensor, usually clipped to the cavity wall or in a duct.
• 3. Check wiring: Inspect the harness for brittle insulation or burn marks. Repair or replace damaged wiring.
• 4. Test the sensor: Disconnect the sensor and measure resistance at room temperature. Compare with service data; an open or near-zero reading indicates failure.
• 5. Replace the sensor: Install a new Privileg cavity sensor of the same specification and remount it securely to ensure proper temperature reading.
