passes through a filter/drier and capillary tubing which cause 

the refrigerant pressure and temperature to drop. It next 

enters the evaporator coil where it absorbs heat from the 

incoming air and evaporates.
The evaporator operates in a flooded condition, which means 

that all the evaporator tubes contain liquid refrigerant during 

normal operation. A flooded evaporator should maintain 

constant pressure and temperature across the entire coil, 

from inlet to outlet.
The mixture of gas and liquid refrigerant enter the 

accumulator after leaving the evaporator coil. The 

accumulator prevents any liquid refrigerant from reaching the 

compressor. The compressor evacuates the cool refrigerant 

gas from the accumulator and compresses it to a high 

pressure and temperature to repeat the process.

5.2 Troubleshooting

No dehumidification, neither hour meter display nor 

compressor run and POWER button does not turn ON.

1.   Unit unplugged or no power to outlet
2.   Defective control board
3.   Loose connection in internal wiring

No dehumidification, neither hour meter display nor 

compressor run with POWER button ON.

1.   Defective control board
2.   Loose connection in internal wiring

Some dehumidification, air mover runs continuously but 

compressor only runs sporadically.

1.   Unit is in defrost cycle, DEFROST light on
2.   Defrost thermistor defective or loose
3.   Loose connection in compressor circuit

4.   Defective compressor overload
5.   Defective compressor
6.   Defective relay
7.   Upper housing is not sealed to lower housing

No dehumidification, air mover runs but compressor does 

not.

1.   Bad connection in compressor circuit
2.   Safety float switch closed, check pump reservoir
3.   Defective compressor capacitor
4.   Defective compressor overload
5.   Defective compressor
6.   Defective control board

Air mover does not run. Compressor runs briefly but cycles 

on and off.

1.   Loose connection in blower circuit
2.   Obstruction prevents impeller rotation
3.   Defective air mover

Unit removes some water but not as much as expected.

1.   Air temperature and/or humidity have dropped
2.   Humidity meter and/or thermometer used are out of 

calibration

3.   Unit has entered defrost cycle
4.   Air filter dirty
5.   Defective defrost thermistor
6.   Low refrigerant charge
7.   Air leak such as loose cover
8.   Defective compressor
9.   Restrictive exhaust or inlet ducting

Unit runs but does not pump water.

1.   Hose kinked or plugged
2.   Pump motor defective
3.   Pump check valve plugged
4.   Bad connection in pump circuit
5.   Hose disconnected internally
6.   Defective control board (pump phase)

Unit pumps water automatically but not when PURGE button 

is pushed.

1.   Bad connection in PURGE button circuit
2.   Defective control board
