Microwave stops heating and displays F2; may occur during a cook cycle or when starting a new cycle.

Safety first: Unplug the Café microwave or turn off the breaker. Allow the unit to cool for at least 30 minutes before inspection.

Steps to try:

• Check ventilation: Ensure upper and rear vents are not blocked by cabinets, foil, or items on top of the microwave. Over-the-range Café models require clear airflow through the top grille and exhaust path.
• Inspect filters: Remove and clean the grease filters and, if installed, the charcoal filter. Clogged filters can cause overheating around the control area.
• Power reset: After cooling, restore power and test with a short 30-second cook cycle using a microwave-safe cup of water. If F2 reappears quickly, the temperature sensor or control is likely faulty.
• Sensor check (visual): The cavity temperature sensor (thermistor) is usually mounted inside the cavity wall or behind the top panel. Look for damaged or burnt wiring harnesses leading to the sensor.
• Next steps: Replacement of the cavity temperature sensor or main control board requires disassembly near high-voltage components. This should be done by a qualified Café technician.
