Possible cause

If the air flow is good and the temperature is not lower than specs for the dehumidifier, the problem is usually a leaky evaporator coil resulting in low refrigerant. When the pressure drops, the temperature drops below freezing in the coil resulting in frosting over. The problem gets steadily worse until the frost goes away (no refrigerant to cool anything) possibly damaging the compressor. The last four units I tested had developed pinhole leaks at the ends of the "U" tube in the coli. Some were less than 3 years old. Cheap copper tubing.
