Microwave shows F17 and may not start or may stop when using sensor cook features.

Safety First: Disconnect power before servicing.

• Clean cavity and sensor port: Food splatter can affect sensor readings. Thoroughly clean the interior, especially around the humidity sensor port, with mild detergent and water. Dry completely.
• Power reset: After cleaning, unplug the unit for 5–10 minutes, then restore power and test sensor cook functions.
• Inspect sensor wiring: Access the sensor from behind the cavity wall or top panel. Check the wiring harness and connector for damage or looseness.
• Test sensor: Use the resistance values in the tech sheet to test the sensor with a multimeter. Replace if readings are out of range.
• Replace components: If the sensor is good but F17 persists, the electronic control board or sensor cook circuit may be defective and require replacement.
