much or
does not cool.
The Mode is set to Power Saver (on
some models).
Use Power Saver only when you are away
from home or asleep, since the fan does
not circulate the room air continuously.
Use Low, High or Turbo for your best
comfort.
The air conditioner is not properly
sized for your room.
Check the cooling capabilities of your
room air conditioner. Room air condi-
tioners 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” in the

Install the air conditioner in a location
where the louvers are free from
curtains, blinds, furniture, etc.
