Room Air Conditioner Troubleshooting Guide
(Continued)
THE AiR CONDiTiONER RUNS TOO MUCH
Check if...
Energy Saver is chosen.
Then ...
inside blower continues operating for one minute to use as muchcooITng 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)
WATER DRiPPiNG FROM AiR CONDiTiONER = iNSiDE ROOM
_sn_t properly installed. I Unit should be mounted on a 1/4" downward slope to the outside (1/2 bubble on
Ja carpenter's level) to provTde proper drainage. ReposTtTonor shim cabTnet as
Inecessary. DO NOT drill drain pan.
WATER DRIPPING FROM AiR CONDITIONER = OUTSNDE ROOM
Check if... Then ...
Room is hot and humid. Normal operation during hot and humid days.
THE REMOTE WILL NOT OPERATE AiR CONDiTiONER
Check if... Then ...
Batteries are not installed properly. Verify batteries are installed properly. (Page 5)
The remote is pointed at the unit. The remote may not work properly when used at extreme angles to the front of
the 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 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 11 )
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 poor wall or window construction or incorrect installation.
(Page 1 1 )
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.
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.
