TROUBLESHOOTING

If you experience operational problems, please follow these troubleshooting suggestions 
before calling Customer Service. If these suggestions fail to solve the problem, 
call Customer Service toll free at 1-877-337-3639.

Unit not operating

• Check to see if the grounded 3-prong plug is

pushed completely into the outlet.

• The fuse may be blown or the circuit has been

tripped. Check the house fuse/circuit breaker.
Replace fuse or reset breaker as needed. 

• The bucket may be full. The dehumidifier 

automatically turns off when this occurs. 
The drain bucket needs to be emptied. 

• If the bucket is not full, it may be positioned 

improperly. Remove and reinstall so that it fits 
all the way into the dehumidifier.

• When the ambient temperature is above 112°F or

below 32°F, the unit will shut off. This protects the
compressor. Wait 3 minutes and then restart. 

Dehumidifier is icing up during initial stage 
of operation.

• This is normal for a dehumidifier. Frost will usually 

disappear within 60 minutes unless the temperature
is below 60°F. 

Airflow is restricted

• Make sure there are no curtains, blinds or furniture

blocking the front or back of the dehumidifier. 

• Clean the filter. It may be clogged. 

NOTE: 

After prolonged usage, the condenser coils behind
the filter may develop a buildup of residue. Unless
cleaned regularly with a soft brush, this residue will
harden and may require special cleaning methods by
a refrigeration/air conditioning professional. 

Unsatisfactory dehumidification 

• When first installed, allow at least 3 or 4 days to

remove the moisture from the room to maintain
the desired dryness. 

• Area to be dehumidified may be too large for

your model. Check with your dealer.

• The controls may not be set correctly. Adjust

controls according to instructions. 

• Doors and windows may not be closed. Check

that all doors, windows and other openings are
closed tightly. 

• Clothes dryer may be in operation in the same

room. Install the dehumidifier away from the
moisture-laden air generated by the dryer. Dryer
should be vented to the outside.

• Please note that when room temperature is

below 60 F, there might be ice forming on the
coils. The unit will go into Auto-Defrost mode to
remove the ice before resuming its dehumidifi-
cation. The defrost operation will reduce the
unit’s ability for moisture removal.
