Possible Causes

Refrigerant leak in evaporator or tubing, Weak compressor, Severely dirty condenser coil, Condenser fan not moving enough air

How to Fix / Troubleshooting

Safety: Do not attempt sealed system repairs yourself. Focus on airflow and basic checks.

  • Verify settings: Confirm both zones are set to the desired temperatures and not in demo or energy-saving mode.
  • Check door seal: Inspect the door gasket for gaps or tears. Replace if it does not seal all around.
  • Clean condenser: Unplug the unit, remove the rear cover, and clean the condenser coil and fan thoroughly.
  • Check fans and compressor: With the cover off and power restored, verify that the compressor and both fans run when cooling is demanded.
  • Observe frost pattern: Remove the interior rear panel and check the evaporator coil. If only a small section frosts or there is no frost, a sealed system issue is likely and requires a professional technician.
