Possible Causes
Failed upper zone thermistor, Loose sensor connector on dual-zone control board, Damaged sensor wiring in partition wall
How to Fix / Troubleshooting
Safety: Disconnect power before removing interior panels between zones.
Steps to address F1 (upper zone):
- Identify affected zone: Confirm that F1 corresponds to the upper zone on your specific Kenmore model (check user manual if available).
- Access upper zone sensor: Remove upper zone shelves. Look for a small plastic cover or channel on the back or side wall where the sensor is located.
- Inspect and test: Remove the cover, inspect the sensor and wiring, and test resistance with a multimeter. Compare to expected NTC values at room temperature.
- Replace sensor: If readings are incorrect or unstable, replace the upper zone temperature sensor (thermistor) with a compatible Kenmore part. Route the new sensor along the original path.
- Reconnect and test: Reassemble, restore power, and verify that F1 clears and the upper zone cools properly.
