Possible Causes
Failed lower zone evaporator fan, Blocked air channel between zones, Lower zone thermistor failure, Partial refrigerant restriction affecting lower circuit
How to Fix / Troubleshooting
Safety: Unplug the unit before removing interior panels.
Steps:
- Check settings: Verify that the lower zone setpoint is lower than ambient and not turned off.
- Inspect airflow: Remove lower zone shelves and panels to check for blocked air passages.
- Test lower zone fan: With panels removed, briefly power the unit and observe if the lower zone fan runs when cooling is demanded. Unplug again before touching anything.
- Replace fan motor: If the fan does not run and has proper voltage, replace the Whirlpool-compatible lower zone evaporator fan motor.
- Check lower thermistor: Test and replace the lower zone thermistor if it reads incorrectly.
- Sealed system: If fans and sensors are good but the lower zone never cools, a sealed system issue may exist and requires professional service.
