Furnace is still running!!!. Does the Fan and Limit Control on a 34 yo
Carrier keep the furnace running once it gets hot enough but the
thermostat hasn't said Stop yet?? I thought not, but the furnace is
still running. If the answer really is NO, something has changed since
the furnace didn't run all night.

I had to leave the furnace room to find an air vent, and indeed, the fan
is blowing.

Since you forced the burner on, but the air
handler blower didn't come on, makes me wonder
if the fan limit switch is open, and reading
high temp overlimit?
