Possible Causes
Dirty air filter or blocked airflow, Iced-up evaporator coil, Low refrigerant charge, Faulty humidity sensor causing premature shutoff
How to Fix / Troubleshooting
Safety: Unplug before cleaning or opening panels.
Steps to improve performance:
- Clean filter and grilles: Wash the air filter and vacuum dust from intake and exhaust.
- Check room conditions: Close windows and doors. Ensure the room is not too large for the unit's capacity.
- Inspect coil for ice: Remove the front cover and check the evaporator coil. If iced, follow the E4/P1 defrost steps and ensure proper airflow.
- Check humidity setting: Set the target humidity to 40–45% to force the unit to run longer.
- Observe coil temperature: If the coil never gets cold while the compressor is running, the sealed system may be undercharged. This requires professional service.
