1991 Hydro Flame furnace: Fan motor runs constantly, even with thermostat disconnected. Where to look?

You can probably find schematics on line with google... IIRC the wall stat only turns off the burner. There is an internal stat that keeps the blower on until the heat exchanger cools down. Probably that internal stat is stuck closed.
