What to do if Koldfront Air Conditioner cools but 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 might be due to a low outdoor temperature (below 64° F/18° C) or a dirty air filter, or the thermostat is set too cold for night-time cooling. Try setting the unit to FAN ONLY mode to defrost the coil. If the air filter is dirty, clean the filter. If the thermostat is set too cold, set the temperature to a higher setting.
