■

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.

■

The Mode is set to Power Saver. Use Power Saver only 
when you are asleep or away from home. Use Cool and a 
higher fan setting 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 conditioners are not designed to cool multiple 
rooms. 

■

The filter is dirty or obstructed by debris. Clean the filter. 

■

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 66°F (19°C). Do not try to 
operate your air conditioner in the cooling mode when the 
outside temperature is below 66°F (19°C).

■

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 Air Exchanger is set to OPEN (on some models). Set 
the Exhaust control to CLOSED for maximum cooling and/or 
heating.

■

Temperature control is not at a cool enough setting. 
Adjust the Temperature control to a cooler setting. Press the 
TEMP minus pad to reduce the temperature by 1º until it 
reaches 66ºF (19ºC). Set the Fan Speed control to High or 
Turbo (on some models).

■

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.
