I have a problem with the Blower continuing to run to long after the burner cycles off. I have heard of limit switches that were not to costly to replace, but would like to know if this is the most likely problem, and where to locate them. This is an approx. 10 year old Bryant 93+ Forced Air Natural Gas Furnace. Thank You in Advance for any help !

I have a problem with the Blower continuing to run
too long after the burner cycles off.

1) Do you have a problem with the blower running until
the heat exchanger/plenum has cooled down to X degrees?
2) How long is "too long"?

Does your circuit board not have some micro switches or gates that can be repositioned to change your fan "off" times?
Check your furnace manual.
