TROUBLESHOOTING

Neither fan nor compressor running. 

 

Dehumidification is being called for. No fan call.

1.  Unit unplugged or no power to outlet.
2.  Humidity control set too high.
3.  Loose connection in internal or control wiring.
4.  Defective Compressor relay.
5.  Defective control transformer.

Compressor is not running. Dehumidification 

 

is being called for. No fan call.

1.  Defective compressor run capacitor.
2.  Loose connection in compressor circuit.
3.  Defective compressor overload.
4.  Defective compressor.
5.  Defrost thermostat open.
6.  Defective compressor relay.

Compressor cycles on and off. Dehumidification 

 

is being called for. No fan call.

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.
5.  Dirty air filter(s) or air flow restricted.
6.  Defective fan relay.

Fan is not running. Dehumidification or 

 

fan is being called for.

1.  Loose connection in fan circuit.
2.  Obstruction prevents fan impeller rotation.
3.  Defective fan.
4.  Defective fan relay.

Low dehumidification capacity (evaporator is 

frosted continuously). Dehumidification is 

 

being called for.

1.  Defrost thermostat loose or defective.
2.  Low refrigerant charge.
3.  Dirty air filter(s) or air flow restricted.
4.  Excessively restrictive ducting connected to unit.

No ventilation. Ventilation is being called for.

1.  Loose connection in ventilation control circuit.
2.  Loose connection in damper power circuit.
3.  Defective fresh air damper.

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 thermostat. 
6.  Low refrigerant charge. 

7.  Air leak such as loose cover or ducting leaks. 

8.  Defective compressor. 

9.  Restrictive ducting. 

10. Optional Condensate Pump Safety Float Switch open. 

Troubleshooting 

Unit doesn't respond to humidity setpoint 

 

on remote wired dehumidistat.

1.  Verify built-in dehumidistat is turned to the  

“OFF” position.

2.  Check calibration of the control to determine  

if it is reading humidity level properly.

3.  Verify control wiring is intact by connecting  

control directly to the terminals of the unit.
