Troubleshooting Procedure for Performance  
Related Issues
This method of diagnosis is used to function 
check the internal components in the dehumidi-
fier. This is to be used when a performance issue 
is suspected.
1.  Set the humidity controller all the way to the 

most humid setting or off position – Did the 
unit shut off?

2.  If yes, turn the fan setting to the ON position – 

does the fan start?

3.  If fan starts, leave in the fan ON position and 

set the humidity all the way to driest setting. 
May have to wait 5 minutes for the compressor 
to start.

4.  Listen for a distinct buzzing/humming sound 

of a compressor starting up – do you hear this 
noise?

5.  If compressor is running and continues to run, 

after about 15 minutes you should feel a slight 
increase in air temperature being discharged 
out of the discharge air side of the unit.

6.  If so, depending on your environmental  

conditions (temp/Rh%), you should see some 
water production out of the hose within  
30 minutes or so. (Note: If the room  
temperature is 55 degrees or below and/or  
in area of low relative humidity, the  
dehumidifier will produce little to no water.
)

7.  Collecting the water removed in a 24 hour period 

will give a measurement of performance. 

 

WARNING!

 

ELECTRICAL SHOCK HAZARD:

  

ELECTRICAL POWER MUST BE PRESENT 
TO PERFORM SOME TESTS. THESE TESTS 
SHOULD BE PERFORMED BY A QUALIFIED 
SERVICE PERSON.

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.

Dehumidifier  
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.  Dirty air filter(s) or air flow 

is restriced. 

5.  Defective defrost  

thermostat. 

6. Low refrigerant charge. 
7.  Air leak such as loose 

cover or ducting leaks. 

8. Defective compressor. 
9. Restrictive ducting.
