same circuit.
Time delay fuse or circuit breaker wrong capacity
is being used. Replace with a time delay fuse or
circuit breaker of the correct capacity. See “Electrical
Requirements”.
An extension cord is being used. Do not use an

RESET (listen for click; Reset button will latch and
remain in) to resume operation.
NOTE: a damaged power supply cord must be
replaced with a new power supply cord obtained from
the product manufacturer and must not be repaired.
Air conditioner runs too long
The current air conditioner replaced an older
model. The use of more efficient 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 units, but this is
not an indication of lesser cooling capacity or
efficiency. Refer to the efficiency rating (EER) and
capacity rating (in BTU/hr.) 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
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 65ºF (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.
NOTE: Do not drill a hole into the bottom of the metal base and condensate pan.
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 or Turbo Cool.
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.
