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.
