Danby DDR45B3WP Use & Care Manual

Occasionally, a minor problem may arise, and a service call may not be necessary- use this troubleshooting guide for a 
possible solution. If the unit continues to operate improperly, call an authorized service depot or Danby’s Toll Free Num-
ber 

for assistance. 

• The 

dehumidifi er is un-

plugged

• 

The fuse is blown/circuit 
breaker is tripped

• Dehumidifi er has reached 

its preset level or bucket is 
full

• 

Bucket is not in the proper 
position

• Power 

failure

• 

Make sure the plug is pushed completely into the outlet

• 

Check the house fuse/circuit breaker box and replace the 
fuse or reset the breaker

• 

The unit turns off automatically when either condition 
occurs. Change to a lower setting or empty the bucket and 
replace properly

• 

The bucket must be in place and securely seated for the 
unit to operate.

• 

There is a protective time delay (up to 3 minutes) to pre-
vent tripping of the compressor overload. For this reason, 
the unit may not start normally for 3 minutes after it is 
turned back on.

• 

Did not allow enough time 
to remove the moisture

• Airfl ow is restricted
• Dirty 

fi lter

• 

The humidity control may 
not be set low enough

• 

Doors and windows may 
not be closed tightly

• 

Clothes dryer may be blow-
ing moisture-laden air into 
the room 

• 

Room temperature is too 
low

• When 

fi rst installed, allow at least 24 hours to maintain the 

desired dryness

• 

Make sure there are no curtains, blinds or furniture block-
ing the front or back of the dehumidifi er. See the “Location” 
section.

• 

See the “Air fi lter” section

• 

For drier air, press the 

 button and set to a lower per-

cent value (%)

• 

Check that all doors, windows and other openings are 
securely closed

• 

Install the dehumidifi er away from the dryer. The dryer 
should be vented to the outside.

• 

Moisture removal is best at higher room temperatures. 
Lower room temperatures will reduce the moisture removal 
rate. Modes are designed to be operated at temperatures 
above 5°C (41°F)

• 

Area to be dehumidifi ed is 
too large

• 

Doors and windows are 
open

The capacity of your dehumidifi er may not be adequate

• 

Close all doors and windows

• 

Unit has been recently 
turned on, or room tempera-
ture is below 5°C (41°F)

• 

This is normal. Frost will usually disappear within 60 min-
utes. See the “Defrost” section

• 

The compressor will turn 
off and the fan will auto-
matically continue to run for 
approx. 3 minutes at a fi xed 
setting

• 

This is normal. Wait approximately 3 minutes and set the 
fan as desired.

• 

Air is moving through the 
dehumidifi er

• 

This is normal

• 

Hose connection may be 
loose

• 

Bucket used to collect wa-
ter, but the hose is attached

Check the hose connection. See “Continuous Drain” sec-
tion

• 

Disconnect the hose if using the bucket to collect water, 
see “Continuous Drain” section.
