Possible Causes
Out-of-tolerance temperature sensor, Poor thermal contact between sensor and cavity, Firmware calibration error on control board
How to Fix / Troubleshooting
Safety first: Disconnect power and allow the unit to cool.
Sensor and mounting:
- Access the cavity temperature sensor and verify it is firmly mounted in its bracket and positioned correctly in the airflow.
- Inspect for grease buildup on the sensor; clean gently with a soft cloth and mild detergent, then dry thoroughly.
- Test the sensor resistance at room temperature and compare to Whirlpool specifications if available. Replace the sensor if readings are significantly out of range.
Control board:
- If a new sensor does not resolve E14, the control board’s calibration or ADC circuit may be faulty. Replace the main control board.
