Possible Causes

Open or shorted upper zone NTC sensor, damaged sensor harness in the upper compartment, loose connector at the zone control board, failed zone sensor input on the PCB.

How to Fix / Troubleshooting

Safety: Unplug the unit before removing interior panels from the upper compartment.

Steps:

  • Locate upper sensor: In dual-zone Dometic wine coolers, the upper zone sensor is typically located behind the upper rear panel or side wall.
  • Inspect and test: Check the sensor body and wiring for damage. Measure its resistance and compare it to expected NTC values. Replace if faulty.
  • Check connections: Ensure the sensor plug is firmly connected to the zone control PCB or main board.
  • Board diagnosis: If a new sensor does not clear F1, the upper zone input on the control board may be defective, and the board should be replaced.
