Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the microwave before internal cleaning near sensors.
User-level checks:
- Clean the interior thoroughly, especially the area near the steam/humidity sensor (often located on the top or side of the cavity behind a small grille). Use a mild detergent and soft cloth.
- Allow the cavity to dry completely, then try a sensor cook program again.
Technician-level checks:
- Locate the humidity sensor module behind the cavity wall or grille.
- Inspect for grease buildup, corrosion, or physical damage.
- Check the sensor's resistance or output voltage according to Hoover specifications.
- Verify continuity of the wiring harness to the control PCB.
- Replace the humidity sensor if readings are out of range; if sensor and wiring are good, replace the control PCB.
Note: Sensor faults often cause inaccurate cooking as well as error codes; replacement restores proper automatic programs.
