I have a tempstar furnace. The fan never turns off. What could be the problem? And if its the fan limit switch is that in a circuit board or is it just a switch that can be replaced?

1. thermostat: fan on or auto? if on, turn it to auto.
2.check fan control at the furnace compartment. pull the white button all the way out.
3. if fan still runs continuously, check the setting of fan control(90-120-200F scale for the thress levers is correct).
4. if no stop, remove the fan control assembly, check for stuck coil or anything screwing the switch.
I don't know what type of furnace you have, the above is just a guess.
I like fixing everything.
