Possible Causes
Low refrigerant charge, Blocked capillary tube or expansion device, Failing compressor, Overheating due to dirty coils or failed fan
How to Fix / Troubleshooting
Safety: Unplug the unit. Do not cut or open refrigerant lines unless you are certified to handle refrigerants.
- Clean airflow components: Remove and clean the air filter. Vacuum dust from the condenser and evaporator coils. Ensure the fan is running at full speed and not obstructed.
- Check room conditions: Confirm the unit is used within the specified temperature range and not in a confined space.
- Inspect for icing: Remove the front cover and look for ice buildup on the evaporator coil. Heavy icing can indicate low airflow or low refrigerant.
- Fan verification: Make sure the fan runs whenever the compressor is on. If the fan is not running, troubleshoot the fan motor and capacitor first.
- Professional diagnosis: If coils are clean, fan is working, and E8 persists with poor dehumidification, the sealed system (refrigerant charge, compressor, or capillary) may be faulty. Contact a qualified refrigeration technician for leak testing and repair.
