Why is my heat coming out cool?
Check your air filter When an air filter is dirty, air cannot easily pass through it, so your furnace has to work overtime to push out heated air. If your furnace has to overcompensate, it might overheat. When a furnace overheats, safety sensors kick in and turn it off and then blow cold air to cool your furnace.

What’s the lowest temperature a furnace fan can run?
FAN-OFF: the lowest temperature setting (blue arrow, the left end of the dial) is the “FAN OFF” temperature. The FAN OFF setting lets the furnace blower continue to run for an interval after the furnace burner has turned off, but will shut the blower off after the heat exchanger has been cooled down to this temperature (usually 90 °F).
Why does my furnace blower only turn on once?
So at some warm air furnace systems the blower might turn on once, even twice after the call for heat has been satisfied. Typically, because the oil or gas burner is NOT running (because the thermostat is not calling for heat), the blower fan should not run more than a minute or two before stopping.
