Possible Causes
Low or lost refrigerant charge, Failed compressor, Severely iced evaporator coil, Blocked airflow across coils
How to Fix / Troubleshooting
Safety: Unplug before removing covers. Do not attempt to open the sealed refrigeration system.
Diagnostic steps:
- Check room conditions: Ensure the room is warm enough (above ~65°F / 18°C) for effective dehumidification.
- Inspect coils: Remove the cover and check if the evaporator coil is icing over. If so, clean the air filter and grilles and allow the unit to defrost.
- Compressor operation: Listen for the compressor running (a low hum) after the fan starts. If the compressor never starts, see compressor-related faults.
- Professional service: If the compressor runs but the coil does not get cold or no water is collected after several hours, the sealed system may be low on refrigerant or restricted. This requires a qualified refrigeration technician; in many compact units, replacement is more cost-effective.
