Check if … Then …
Unit is not properly installed.
Unit should be mounted on a 1/4" downward slope to the outside (1/2 bubble on
a carpenter’s level) to provide proper drainage. Reposition or shim cabinet as
necessary. DO NOT drill drain pan.
Check if … Then …
Room is hot and humid. Normal operation during hot and humid days.

Room Air Conditioner Troubleshooting Guide
Normal Sounds
High Pitched Whine
Today’s high efficiency
compressors may have a
high pitched whine during
the cooling cycle.
Sound of Rushing Air
At the front of the unit,
you may hear the sound
of rushing air being moved
by the fan.
Gurgle/Hiss
“Gurgling or hissing” noise may
be heard due to refrigerant passing
through evaporator during normal
operation.
Unit may vibrate and make
noise because of poor wall
or window construction or
incorrect installation.
Vibration
Newer, higher efficiency Air Conditioner may run longer to cool the room. Total
energy consumption is less due to higher efficiency.
Current Unit replaced an older unit.
Inside blower continues operating for one minute to use as much cooling that is
available in the evaporator.
Energy Saver is chosen.
THE AIR CONDITIONER RUNS TOO MUCH
Check if … Then …
BTU size is too small.
A higher capacity unit may be required depending on the size of the room being
cooled. (Page 9)
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.
Fan/Motor - Normal noise of higher efficiency fans pushing air further into the
room. (Page 11)
Pinging or swishing sounds.
Condenser - Normal noise of water hitting the condenser to increase energy
efficiency. (Page 11)
Evaporator - Normal noise of refrigerant passing through evaporation. (Page 11)Gurgling or hissing sounds.
Beeping.
Electronic Control - Normal noise when electronic control settings are changed.
Vibration.
Unit Vibration - Due to poor wall or window construction or incorrect installation.
(Page 11)
Droplets of water hitting condenser
during normal operation may cause
“pinging or swishing” sounds.
Note: Don't try to drill any holes
on the base pan to eliminate the
normal sounds otherwise it will
void the warranty.
