tripped.
Airflow is restricted.
The temperature control may not
be set correctly.
The air filter is dirty.
The room may be too warm.
Cold air is escaping.
The cooling coils are frozen.
Ice blocks the air flow and stops
the air conditioner from cooling
the room.
Hot and humid weather.
The air conditioner is not correctly
tilted outside.
Moisture removed from the air is
draining into the base pan.
The batteries are inserted
incorrectly.
The batteries may be dead.
Make sure the electrical plug is pushed completely
into the outlet.
Check the main fuse/circuit breaker box and replace
the fuse or reset the breaker.
The unit will automatically restart when power is

after it is turned on.
• Press reset button located on the power cord plug.
• If reset button will not stay engaged, discontinue
use of the air conditioner and contact a qualified
service technician.
Make sure there are no curtains, blinds or furniture
blocking the front of the air conditioner.

Clean the filter. See Care and Cleaning on page 8.
Allow time for the room to cool down after turning on
the air conditioner.
Check for open furnace registers and cold air returns.
See "Air Conditioner Freezing Up" below.
Set the mode dial to high fan or high cool and set the
thermostat to a higher temperature.
This is normal.
For proper water drainage, make sure the air
