Room Air Conditioner Troubleshooting Guide
(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, hTgher 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)
WATER DRIPPING FROM AIR CONDITIONER - INSIDE ROOM
I Unit should be mounted on a 1/4" downward slope to the outside (1/2 bubble on a
I Unit is not properly installed. I carpenter's level) to provide proper drainage. Reposition or shim cabinet as necessary.
I DO NOT drill drain pan.

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 1 1 )
Rushing air sound. Fan/Motor - Normal noise of higher efficiency fans pushing air further into the room.
(Page 1 1)
Pinging or swishing sounds. Condenser - Normal noise of water hitting the condenser to increase energy efficiency.
(Page 1 1)
Gurgling or hissing sounds. Evaporator - Normal noise of refrigerant passing through evaporation. (Page 1 1 )
Beeping. Electronic Control - Normal noise when electronic control settings are changed.
Vibration. Unit Vibration - Due to _oor wail or window construction or incorrect installation. (Page 1 1
Normal Sounds
_nl_n_l nf Rl_hln_ 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.
High Pitched Whine
Today's high efficiency
compressors may have a
high pitched whine during
the cooling cycle.
Vibration
Unit may vibrate and make
noise because of poor wall
or window construction or
incorrect installation.
