Possible Causes

Dirty air filter, iced evaporator coil, low refrigerant charge, faulty compressor, blocked airflow

How to Fix / Troubleshooting

Safety: Unplug the unit before cleaning or inspection.

  • Clean filter: Remove and clean the air filter thoroughly.
  • Check room conditions: Ensure the room is warm enough (above 18°C) and humid. Dehumidifiers work poorly in cold rooms.
  • Inspect coils: If accessible, check the evaporator coil for ice. If iced, let the unit thaw completely and restart.
  • Observe compressor: When running, the compressor should produce a gentle humming and the condenser coil should feel warm. If the compressor never starts, there may be an electrical or refrigerant issue.
  • Persistent poor performance: This may indicate a sealed-system problem (refrigerant leak or weak compressor) requiring a refrigeration technician.
