How to Fix / Troubleshooting

Safety: Unplug the unit before accessing upper zone panels.

Steps:

  • Verify settings: Ensure the upper zone is turned on and set to a temperature below ambient.
  • Access upper zone fan: Remove shelves and the rear panel to expose the fan and thermistor.
  • Test fan operation: Briefly power the unit and observe if the upper fan runs when cooling is called for. Disconnect power again before handling.
  • Replace fan motor: Install a new Whirlpool-compatible upper zone evaporator fan if the existing one fails to run.
  • Check thermistor: Test and replace the upper zone thermistor if readings are out of range.
  • Control board: If the fan never receives power, the control board may be defective and require replacement.
