How to Fix / Troubleshooting
Safety first: Unplug the microwave.
Cleaning and inspection:
- Locate the humidity sensor inside the cavity (often behind a small grill or cover on the top or side wall) or in the air outlet path.
- Clean the area around the sensor with a soft, dry cloth to remove grease and moisture residue.
- Do not soak or spray cleaner directly onto the sensor.
Internal check (experienced users):
- Remove the outer cover and inspect the sensor wiring harness to the control board.
- Ensure connectors are fully seated and free of corrosion.
After cleaning: Reassemble and test an auto program. If E17 persists, the humidity sensor may need replacement by a technician.
