Room Air Conditioner
Troubleshooting
(Continued)
THE AIR CONDITIONER
RUNS TOO MUCH
Check
if...
Then...
Energy Saver is chosen.
Inside blower continues operating for one minute to use as much cooling that is
available in the evaporator.
Current Unit replaced an older unit.
Newer, higher efficiency Air Conditioner
may run longer to cool the room. Total
energy consumption
is less due to higher efficiency.
BTU size is too small.
A higher capacity unit may be required depending on the size of the room being
cooled. (Page 9)

level) to provide proper drainage. Reposition or shim cabinet as
/necessary.
DO NOT drill drain pan.

unit.
TYPICAL
AIR CONDITIONER
SOUNDS YOU MAY HEAR
Check
if...
Then...
High pitched whine or pulsating noise that cycles on and off.
Compressor - Normal noise due to modern high efficiency compressors.
(Page 11)
Rushing air sound.
FantMotor - Normal noise of higher efficiency fans pushing air further into the room.
(Page 11)
Condenser - Normal noise of water hitting the condenser to increase energy
Pinging or swishing sounds,
efficiency. (Page 11)
Gurgling or hissing sounds.
Evaporator - Normal noise of refrigerant passing through evaporation.
(Page 11)
Beeping.
Electronic Control - Normal noise when electronic control settings are changed.
Vibration.
Unit Vibration - Due to poor wall or window construction or incorrect installation.

Guide
Normal
Sounds
Sound of Rushing Air
At the front of the unit,
you may hear the sound
of rushing air being moved
by the fan.
High Pitched Whine
Today's
high efficiency
compressors
may have a
high pitched whine during
the cooling cycle.
Gurgle/Hiss
"Gurgling
or hissing" noise may
be heard due to refrigerant
passing
through evaporator
during normal
operation.
Vibration
Unit may vibrate and make
noise because
of poor wall
or window
construction
or
incorrect installation.
Pinging or Swishing
Droplets of water hitting
__
condenser during normal
operation may cause
"pinging or swishing"
sounds.
