Possible Causes
• The air conditioner plug is
not completely inserted in
the electrical outlet.
• The house fuse is blown or the
circuit breaker has tripped.
• Power failure.
• The integrated circuit breaker in the
plug has tripped.
P2 appears in the display.
•
• Room temperature is less than the
set temperature.
• Airflow is restricted.
• The air filter is dirty.
• The room is very hot, or not enough
time allowed for cooling.
• Cold air is escaping.
• Cooling coils have iced up.
• Area to be cooled is too large for
the air conditioner.
• Doors or windows are open.
Solutions
• Make sure electrical plug is plugged completely into a
live, properly grounded outlet.
• Replace the fuse or reset the circuit breaker. Make sure
that there are no other appliances on the same circuit.
• If a power failure occurs, turn the power OFF. When
power is restored, wait 3 minutes before restarting the
air conditioner.
• Press the RESET button on the air conditioner plug.
If the reset button will not stay engaged, unplug the air
conditioner and contact a qualified service technician.
The water collection tank is full. Drain the tank and
reset your settings.
• This is normal. The air conditioner automatically
shuts off when the room equals or is less than the
set temperature. Adjust the temperature setting,
if needed.
• Make sure there is sufficient clearance around the
air conditioner and that the air inlet and outlet are
not blocked by furniture, curtains, etc.
• Clean the air filter at least every two weeks. See the
Care and Cleaning section.
• When first turned on, allow the air conditioner
sufficient time to cool the room.
• Check for open furnace floor registers or cold air
returns, or open windows or doors.
• In especially hot, humid weather and when the air
conditioner is running frequently or for extended
periods, ice can form on the cooling coils, blocking
air flow. Set the controls to High Fan or High
Cool, and set to a warmer temperature.
• Consult your dealer for the air conditioner capacity
necessary to cool the desired area.
• Make sure doors and windows are closed.
