How to Fix / Troubleshooting

Safety: Unplug the unit before accessing lower zone panels.

Steps to address F2 (lower zone):

  • Confirm zone mapping: Verify that F2 corresponds to the lower zone on your Kenmore model.
  • Access lower zone sensor: Remove lower shelves and any interior panel covering the sensor channel.
  • Inspect wiring: Look for pinched or cut wires, especially near the divider between zones.
  • Test thermistor: Disconnect and measure resistance at room temperature. Replace the lower zone temperature sensor (thermistor) if readings are open, shorted, or out of spec.
  • Reassemble and test: Restore power and monitor the lower zone for several hours to ensure stable temperature and that F2 clears.
