Possible Causes
Low refrigerant charge or leak, Severely dirty evaporator or condenser coil, Faulty compressor, Blocked capillary tube or expansion device
How to Fix / Troubleshooting
Safety: Unplug the unit before cleaning. Do not attempt to open the sealed refrigeration system.
- Check humidity setting: Ensure the target humidity is set lower than the current room humidity.
- Clean filter and coils: Remove and wash the air filter. Access both coils and gently clean dust and lint with a soft brush and vacuum.
- Observe evaporator: After running for 15–20 minutes, the evaporator should be uniformly cool with some condensation. If only a small section is cold or there is no cooling, a sealed system issue is likely.
- Room conditions: Verify the room is closed (doors/windows) and not too cold; low temperatures reduce water collection.
- Professional service: If cleaning and proper setup do not restore performance, contact a refrigeration technician to check refrigerant charge and compressor health.
