Can someone help me with what the limit switch setings should be on my forced air natural gas furnace. It has a dial with 3 slide settings on it.
Thanks in advance

Are you sure what you have is the fan limit control, that you are looking at. If so the limit should be set about 200o. The fan side fan on about 110or120 the fan off 90 or 95. The fan off is just so it dont blow cold air. make sure just what you have and are trying to set;) ED
