SOURCE: my goodman furnacs says my
the limit switch tells the fan when its time to come on. when the temp falls the unit will fire up. it is a small box on the front the wire from the burner is wired to it and so is the fan pull the cover off and you will see a dile with two settings on it when the unit fires up it reaches the first mark that turnes the fan on when it reaches the recond mark the fire box shuts down the fan continues to run
un till the dile turnes back to the first mark and then the fire box comes back on un till the desired temp is reached in the house
