TROUBLESHOOTING

The Unit is NOT working:

• 

Why do you believe the dehumidifier is not working?

• 

Is the power ON?

• 

Has the breaker tripped? – Reset breaker

• 

If in a wet area, is the unit plugged into a GFI protected cir-
cuit? – Excessive moisture will trip GFI. Remove from area.

• 

Is the unit being run off a generator? - Check output does 
not fluctuate as the unit will not operate at low voltage.

• 

If  using  an  extension  cord  -  Is  the  cord  of  the  correct 
gauge for the distance run? (14 AWG up to 25’ and 12 
AWG over 25’). Note: Verify voltage while unit is starting. 
Start up will cause the highest current draw and largest 
voltage drop. Even if plugged directly to outlet there can 
be a significant voltage drop. Never assume the voltage is 
ok without verifying.

• 

Is the unit draining? – Check the condensate receptacle. 
If full, the float is up and the unit will not operate – drain 
receptacle. 

• 

Overpressure switch tripped. Check for fan failure or high 
ambient temperature. Display panel indicates defrost.

The unit continually ices up: Note that some ice buildup on the 

evaporator coils is normal but airflow should not be blocked.

• 

Is the fan working? – Fan not working, check run capacitor 
and fan unit.

• 

Is warm air blowing out the front of the unit? - No warm 
air, temperature may be too low. Raise temperature with 
supplementary source.

• 

Is  the  air  filter  clean  and  airflow  unobstructed?  –  Clean 
filter.  Unit  should  have  a  minimum  of  10”  clearance  all 
around it.

• 

Dirty evaporator coils? – Clean coils.

• 

Defrost  thermostat  loose  or  not  working?  –  Secure  or 
replace. 

• 

Defrost  timer  set  incorrectly  or  defective?  –  Reset  or 
replace.

• 

Temperature  in  the  operating  space  is  too  low?  -  Raise 
temperature with supplementary source.

Unit moves some water but not as much as expected:

• 

Air temperature and Relative Humidity have dropped - Check 
levels with calibrated humidity meter and/or thermostat. 

• 

Unit is in defrost cycle – Unit will start after cycle.

• 

Air filter dirty or airflow obstructed - Unit should have a 
minimum of 10” clearance all around it. Clean air filter and 
ensure adequate airflow/space around unit.

• 

Evaporator coils dirty – Clean coils.

• 

Restrictive or kinked exhaust ducting (if used) – Straighten 
out ducting.

• 

Defrost timer set incorrectly for conditions – Reset timer.

• 

Defrost thermostat defective - Replace

• 

Refrigerant charge is low – Have unit checked by qualified 
technician

• 

Defective compressor – Replace compressor by qualified 
technician as it requires recycling of refrigerant. 

Unit runs continuously for days:

• 

Unit is working removing water - High Relative Humidity 
in space.

• 

Humidity or water is getting into the space – Find source 
and stop it.

• 

Unit is undersized for space – Use larger unit or mul-
tiple units.

• 

Poor  air  movement  in  space  –  Use  air  movers  to 
increase movement.

Unit runs but does not pump water:

• 

Drain hose kinked or blocked – Straighten or unblock hose.

• 

Pump float stuck closed – Reset or replace.

• 

Pump not working – Check electrical operation with out-
side supply.

• 

Hose disconnected internally – Reconnect hose.

• 

Compressor capacitor bad – Check capacitor.

Fan runs but Compressor does not:

• 

Condensate pump not working – Check pump and float.

• 

Bad connection in pump circuit – Check connections.

• 

Bad compressor capacitor – Check capacitor.

• 

Defective control board – Replace.

• 

Defective compressor – Replace compressor by quali-
fied technician.

• 

Defective time delay or Thermistor – Check and/or replace.

• 

Defective pressure switch – Check and replace.

Fan does not run. Compressor runs briefly but cycles on/off:

• 

Defective fan capacitor – Check capacitor. 

• 

Loose connection in fan circuit – Check connections.

• 

Fan obstructed and not turning – Remove obstruction.

• 

Defective fan – Replace fan.

• 

Defective control board – Replace control board.
