Troubleshooting Tips

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. 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 or a tripped breaker. This guide shows the
proper fuse size on page 3.
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), and
below 115°F (46°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 becomes 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 operation.
Frosting
This usually occurs because of insufficient airflow across
the coils, a dirty filter, cool damp weather, 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 conditioner mounted
in a wall is quieter than one mounted in a window.
Cleaning your air conditioner
The decorative front and the cabinet can be cleaned with
warm water and a mild liquid detergent. 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.
