Possible Causes

Room temperature too low, Restricted airflow due to dirty filter, Faulty evaporator temperature sensor, Low refrigerant charge

How to Fix / Troubleshooting

Safety: Unplug the unit before cleaning. Do not chip ice with sharp tools.

  • Defrost: Turn off and unplug the dehumidifier. Allow all ice to melt completely. Place towels to catch water.
  • Clean filter and coils: Wash the air filter and vacuum dust from coils to restore airflow.
  • Check room temperature: Use the unit only within the recommended temperature range. Move it to a warmer room if necessary.

If freezing continues despite good airflow and proper room temperature, the evaporator sensor or refrigerant charge may be at fault. A technician should test sensors and sealed system pressures.
