Power is OFF. Turn power ON.
Air from unit does not feel cold enoughRoom temperature below (11°C). Cooling may not occur until room temperature rises above 62°F(17°C).
Temperature sensing behind air filter element touching cold coil. Keep it from the cold coil.
Set to a Lower temperature.
Compressor stopped when changing modes. Wait for 3 minutes after set to the COOL mode.
Air conditioner cooling, but room is too war mice forming on cooling coil behind decorative frontOutdoor temperature below 64°F(1ffC). To defrost the coil, set FAN ONLY mode.
Air filter may be dirty. Clean filter. To defrost, set to FAN ONLY mode.
Thermostat set too cold for night-time cooling. To defrost the coil, set to FAN ONLY mode. Then, set temperature to a Higher setting.
Air conditioner cooling, but room is too warm NO ice forming on cooling coil behind decorative front.Dirty air filter air restricted. Clean air filter.
Temperature is set too High, set temperature to a Lower setting.
Air directional louvers positioned improperly. Position louvers for better air distribution.
Front of units is blocked by drapes, blinds, furniture, etc. restricts air distribution. Clear blockage in front of unit.
