Air Conditioner cycles on and off too
often, or does not cool room in cooling
mode
The air conditioner is not properly sized for your
room.
Check the cooling capabilities of your room air
conditioner. Room air conditioners are not designed to
cool multiple rooms.
The filter is dirty or obstructed by debris.
Clean the
filter.
The inside evaporator and outside condenser coils
are dirty or obstructed by debris.
See “Annual
Maintenance.
There is excessive heat or moisture (open
container cooking, showers, etc.) in the room.
Use
a fan to exhaust heat or moisture from the room. Try
not to use heat-producing appliances during the
hottest part of the day.
The louvers are blocked.
Install the air conditioner in
a location where the louvers are free from curtains,
blinds, furniture, etc.
The outside temperature is below 64ºF (18ºC).
Do
not try to operate your air conditioner in the cooling
mode when the outside temperature is below 65ºF
(18ºC).
The temperature of the room you are trying to cool
is extremely hot.
Allow extra time for the air
conditioner to cool off a very hot room.
Windows or doors to the outside are open.
Close
all windows and doors.
The Vent control is set to open (on some models).
Push the Vent control to CLOSED for maximum
cooling and/or heating.
The temperature set point or Thermostat control is
not at a cool enough setting.
Adjust the temperature set point to a cooler setting by
pressing the minus button to reduce the temperature
or adjust the Thermostat control to a cooler setting by
turning the knob clockwise. Turn the Fan control to
HIGH.
Sling fan operation
Window air conditioners have a sling fan as a standard
feature. As condensate is accumulated in the pan the
fan blade will pick up the water and sling it on the
outdoor side coils. This feature provides for a more
efficient operation. Occasionally, the slinging noise can
be heard.
Temperature on display does not match
room temperature
When the compressor and fan motor turn off
during Power Saver mode, or after you turn off the
unit, a lower temperature reading than the actual
room temperature may be displayed for a short
period of time.
This lower temperature reading is
caused by the temperature sensor being located close
to the cold evaporator coil. The actual room
temperature will display within a few minutes.
Water drips from cabinet into your house
The air conditioner is not properly leveled.
The air
conditioner should slope slightly downward toward the
outside. Level the air conditioner to provide a
downward slope toward the outside to ensure proper
drainage. See the Installation instructions.
NOTE:
Do not drill a hole into the bottom of the metal base and condensate pan.
