How to Fix / Troubleshooting

Safety first: Unplug the Café microwave or shut off the breaker. Internal components can remain hot after use.

Steps to try:

Check external airflow: Ensure the top grille and bottom intake areas are not blocked by cabinets, foil, or debris. For over-the-range Café models, verify that the damper and ductwork are not crushed or blocked.
Clean filters: Remove and clean grease filters. If equipped, replace the charcoal filter according to the user manual.
Power reset: After 15 minutes, restore power and run a short cook cycle with a cup of water. Listen for the internal cooling fan starting when the magnetron should be heating.
If fan is silent or noisy: The internal cooling fan motor may be seized or its wiring damaged. This requires removing the outer cover and working near high-voltage parts.
Service needed: Have a Café technician test the fan motor and fan relay on the main control board and replace the failed component.

Microwave shows F8 and may stop mid-cycle; fan may run unexpectedly or not at all.
