Troubleshooting T ips
Power failure
If you have a power failure, the unit's auto-restart feature
will resume operation in the selected mode prior to the
power failure
Won't cool?
If your air conditioner operates, but won’t cool; check to
see if the controls are properly set. Check the filter and
clean thoroughly if needed. Check to see if the vent door is
closed. Check to see if the chassis seal gasket is installed
(refer to installation instructions). Lastly, you can reset
the circuit board by pressing the “MODE” button and the
“TEMPERATURE DOWN” button at the same time. The
LEDs (small red lights) for Hour, Start and Stop will begin
blinking. Once this occurs, turn the unit off by pressing
the On/Off button once and then unplug the unit. Finally,
plug the unit back in and turn it on by pressing the On/Off
button once. All settings revert back to the factory default
settings.
Won't run?
Make sure the power cord is plugged in all the way. Check
for a bad fuse, tripped breaker or tripped LCDI Device.
Refer to page 3 for LCDI reset instructions and to confi rm
proper fuse size. Lastly, you can reset the circuit board by
pressing the “MODE” button and the “TEMPERATURE
DOWN” button at the same time. The LEDs (small red
lights) for Hour, Start and Stop will begin blinking. Once
this occurs, turn the unit off by pressing the On/Off button
once and then unplug the unit. Finally, plug the unit back
in and turn it on by pressing the On/Off button once. All
settings revert back to the factory default settings.
This is a warm weather appliance
Your air conditioner is designed to cool in warm weather
when the outside temperature is above 60°F (16°C), so it
won't cool a room if it is already cool outside.
Condensation is normal
Air conditioners actually pump heat and humidity from your
room to the outside air. Humidity be comes water, and your
air conditioner will use most of the water to keep the outside
coil cool. If there is excessive humidity, there may be excess
water that will drip outside. This is normal op er a tion.
Frosting
This usually occurs because of insufficient airflow across
the coils, a dirty filter, cool damp weath er, or all of these.
Set unit to Fan Only and the frost will disappear. Setting
the thermostat a little warmer will probably prevent the
frosting from recurring.
Noises
All air conditioners make some noise. We build them to
operate as quietly as possible. An air con di tion er mounted
in a wall is quieter than one mounted in a window. It is
important to ensure that the chassis seal gasket is properly
installed (refer to installation instructions).
Cleaning your air conditioner
The decorative front and the cabinet can be cleaned with
warm water and a mild liquid de ter gent. The indoor coil can
be vacuumed with a dusting attachment if it appears to be
dirty. The outdoor coil can be gently sprayed with a hose
if you can get to it. If not, you might call your dealer for a
more thorough cleaning when needed. The air fi lter should
be inspected weekly and cleaned if needed by vacuuming
with a dust attachment or by cleaning in the sink using warm
water and a mild dishwashing detergent. Dry thoroughly
before reinstalling the fi lter.
