The blower fan on our furnace won't stop running.. Why?

The easiest thing to look for and remedy is to see if the "Fan" switch (http://www.azpartsmaster.com/images/catalog/ashop/A37220.jpg) (look at the upper right part) on the thermostat is set to ON instead of AUTO. Your thermostat is probably different, but should have a similar switch.
The other option is a short in the fan circuit :(
Hope it is the switch!
