Blower runs with fan switch OFF, but compressor
cycles on & off.
1. Low ambient temperature and/or humidity causing unit
to cycle through defrost mode.
2. Defective compressor overload.
3. Defective compressor.
4. Defrost thermostat defective.
Blower does not run with fan switch in either position.
Compressor runs briefly but cycles on & off.
1. Loose connection in blower circuit.
2. Obstruction prevents impeller rotation.
3. Defective blower.
4. Defective blower switch.
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.
7.3 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.
