Evaporator coil frosted continuously, low dehumidifying capacity.
1.Defrost thermostat loose or defective.
2.Low refrigerant charge
3.Dirty air filter or air flow restricted.
8.3 Defrost Thermostat
The defrost thermostat is attached to the refrigerant suction tube between the accumulator and compressor. It will automatically shut the compressor off if the low side refrigerant temperature drops due to excessive frost formation on the evaporator coil. The blower will continue to run, causing air to flow through the evaporator coil and melt the ice. When the ice has melted, the evaporator temperature will rise and the thermostat will restart the compressor.
