Possible Causes
Failed lower zone NTC sensor, Loose sensor connector, Damaged harness to lower zone, Faulty control PCB channel for lower zone
How to Fix / Troubleshooting
Safety: Unplug the appliance before working inside the cabinet.
- Locate lower zone sensor: Remove the lower racks and the rear interior panel of the lower compartment to access the sensor.
- Inspect wiring: Check for damage or disconnection of the sensor harness. Reseat the connector at both the sensor and PCB ends.
- Measure resistance: Use a multimeter to test the sensor at room temperature. Replace the lower zone NTC sensor if readings are abnormal.
- Reassemble and test: After replacement, reassemble the panel, restore power, and confirm that F2 clears and the lower zone stabilizes.
- Control board check: Persistent F2 with a known-good sensor suggests a faulty PCB input, requiring board replacement.
