Problem Solution
Air conditioner seems to run too much □ The current air conditioner replaced an older model. The use of
more efcient components may cause the air conditioner to run
longer than an older model, but the total energy consumption
will be less. Newer air conditioners do not emit the “blast” of
cold air you may be accustomed to from older air conditioners,
but this is not an indication of lesser cooling capacity or ef-
ciency. Refer to the efciency rating (EER) and capacity rating
(in Btu/h) marked on the air conditioner.
□ The air conditioner is in a heavily occupied room, or heat
producing appliances are in use in the room. Use exhaust vent
fans while cooking or bathing and try not to use heat producing
appliances during the hottest part of the day. A higher capacity
air conditioner may be required, depending on the size of the
room being cooled.
Air conditioner cycles on and off too much or does not cool □ 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 lter is dirty or obstructed by debris. Clean the lter.
□ 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 mois-
ture 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 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 Temp control is not at a cool enough setting. Adjust the
Temp control to a cooler setting by pressing the minus button to
reduce the temperature. Set the Fan Speed control to the high-
est setting.
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 in the bottom of the metal
base and condensate pan.
