Solution 4:
Air Filter
If the air filter becomes clogged with dirt, it will restrict the airflow over the evaporator coils. If the airflow is restricted, the evaporator coils will get too cold. Then, as humid air passes ove...r the evaporator coils, the air will condense on the coils and freeze. Eventually, the entire evaporator coil assembly will frost over. If the air filter is dirty, clean or replace it.

Solution 5:
Air Flow Problem
Most standard dehumidifier models require the room temperature to remain above 65 degrees Fahrenheit. If the room temperature is below 65 degrees Fahrenheit, the dehumidifier coils will frost up. If the temperature in your home regularly drops below 65 degrees, you will need to obtain a model that is specifically designated for lower temperature operation.
