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. Check
to see if the vent door is closed. Check to see if the chassis seal gasket is
installed (refer to installation instructions).
Won't run?
Make sure the power cord is plugged in completely. Check for a bad fuse,
tripped breaker or tripped LCDI Device. Refer to page 3 for LCDI reset
instructions and to con
¿rm proper fuse size.
For QuietMaster Programmable models only:
You can reset the circuit board by pressing the “Moneysaver” button and
the “Check Filter” button at the same time. The LED (small red light) for
the Check Filter 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) and below 115°F (46°C), so it won't
cool a room if it is already cool outside.
If you want to cool a room in the
spring or fall, touch Fan Only and set the Fresh Air/Exhaust control to
Fresh Air
. This will bring in a supply of cooler outside air.
Condensation is normal
Air conditioners actually pump the heat and humidity from your room to the

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. Friedrich QuietMaster

units are
designed to operate as quietly as possible. An air conditioner 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

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
¿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 the
¿lter thoroughly before reinstalling. Use caution– the coil surface
can be sharp.
Heat pumps operate differently
If your unit is a "Y", or heat pump model, there are some things that you
will want to be aware of.
Some functions of a heat pump differ from your unit when it is used for
heating:
1. It is normal for ice to form on the outdoor coil of the heat pump.
Moisture in the outside air, passing over the coil when very cold,
will form ice.
2. If the outdoor temperature drops below 37°F (3°C), your heat pump

temperature rises to 40°F (4°C), the compressor will resume the
heat pump operation. If your unit is a 115 volt model (YS09), it is
designed for use in warmer climates and has no electrical heat
feature, and will not provide adequate heat below 37°F (3°C).
