Dehumidifier shows EC and stops cooling; fan may still run.

Safety: Unplug the unit. Do not attempt to open the sealed refrigeration system yourself.

• Clean coils and filter: Ensure both evaporator and condenser coils are clean and the air filter is washed and dried. Poor airflow can mimic refrigerant issues.
• Check for icing: After running briefly, inspect the evaporator coil. Heavy ice buildup or only partial frosting can indicate low charge or restriction.
• Sensor inspection: Verify that the coil temperature sensors are firmly attached and their wiring is intact. Replace any suspect coil temperature sensors.
• Professional diagnosis: If EC persists, a licensed technician should check system pressures, locate leaks, and recharge or repair the sealed system as needed.
