AIRCARE dehumidifier displays EC and stops dehumidifying.

Safety first: Unplug the dehumidifier. Do not attempt to open the sealed refrigeration system; that requires certified service.

• Step 1 – Check ambient conditions: Ensure the room temperature is within the unit’s operating range (typically above 41°F / 5°C). Very cold rooms can cause coil icing and EC errors.
• Step 2 – Inspect for ice: Remove the front or rear grille and look at the evaporator coil. If it is covered in ice, turn the unit OFF and allow it to thaw completely (this may take several hours).
• Step 3 – Clean filter and coils: Wash or vacuum the air filter. Gently clean dust from the evaporator and condenser coils to improve airflow.
• Step 4 – Restart and monitor: After thawing and cleaning, plug in and run the unit. If EC returns quickly and the coil does not get uniformly cold, there may be a refrigerant issue.
• Step 5 – Sensor check: If accessible, inspect the evaporator temperature sensor for secure mounting and intact wiring. Replace if damaged.

Persistent EC often indicates a sealed system problem (leak or low charge). Contact an authorized AIRCARE service provider; sealed system repairs are not DIY-safe.
