Possible Causes

Incorrect line voltage, Miswired installation, Faulty main control board, Internal line filter failure

How to Fix / Troubleshooting

Safety first: Turn off the circuit breaker supplying the Café microwave. Do not attempt to rewire the unit unless you are qualified.

Steps to try:

  • Verify power source: Confirm the microwave is connected to a properly grounded 120V, 60Hz circuit as specified in the Café installation instructions.
  • Check for extension cords: Do not use extension cords or power strips; plug the microwave directly into a dedicated outlet.
  • Power reset: After 5–10 minutes, restore power and see if F9 clears.
  • If F9 persists: The main control board or line filter assembly may be defective. This requires internal testing with a meter and should be performed by a qualified Café technician.
