Why is my Koldfront Air Conditioner cooling but the room is too warm and ice is forming?

If your Koldfront Air Conditioner is cooling, but the room is too warm and ice is forming on the cooling coil, it could be due to several reasons: * The outdoor temperature is below 18°C (64°F). Set the unit to FAN ONLY mode to defrost the coil. * The air filter may be dirty. Clean the filter and set the unit to FAN ONLY mode to defrost. * The thermostat is set too cold for night-time cooling. Defrost the coil by setting the unit to FAN ONLY mode, then increase the temperature setting.
