Why does my Keystone Air Conditioner turn on and off rapidly?
Your Keystone Air Conditioner might be turning on and off rapidly due to a dirty air filter restricting airflow. Clean the air filter to resolve this. Alternatively, if the outside temperature is extremely hot, try setting the FAN speed to a higher setting to increase airflow past the cooling coils.

What to do if my Keystone Air Conditioner is cooling, but the room is too warm and there is no ice forming?
If your Keystone Air Conditioner is running but the room isn't cooling down and no ice is forming, start by cleaning the air filter, as a dirty filter restricts airflow. Ensure the temperature isn't set too high; lower it. Check the air directional louvers and adjust them for better air distribution. Make sure that drapes, blinds, or furniture aren't blocking the front of the unit. Also, close any open doors, windows, or registers to prevent cold air from escaping. If you've just turned the unit on in a hot room, allow extra time for it to remove stored heat from the walls, ceiling, floor, and furniture.
