Essick Air Evaporator Coil Icing (Dehumidifier)

Dehumidifier coils freeze over with ice and airflow is reduced.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

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

Safety first: Unplug the unit and allow ice to melt completely before further use.

Check room temperature: Operate the dehumidifier only within the recommended temperature range.
Clean air filter and coils: Wash or replace the air filter. Gently vacuum dust from the coils.
Ensure proper clearance: Keep at least 12 inches of clearance around the unit for airflow.
Test after thawing: Plug in and run. If icing recurs quickly, the refrigerant charge or defrost system may be faulty and requires professional service.
