How to Fix / Troubleshooting
Unplug the unit before accessing internal components.
Steps:
- Identify affected zone: Determine whether the upper or lower zone is not cooling.
- Check zone fan: Remove the interior panel for the affected zone and verify that its internal fan runs when the unit is on. Replace the zone evaporator fan motor if it does not run.
- Inspect air ducts: Ensure that any air passages between zones are not blocked by insulation or debris.
- Test zone sensor: Measure resistance of the zone's temperature sensor and replace if faulty.
- Replace zone Peltier module: If the fan and sensor are good but the zone remains warm, replace the Peltier cooling module serving that zone.
