look at the air handler fan and limit switch. It may have a Honeywell style that has a white plastic knob on it that over rides this and continually runs the fan. It would have a sensor that would project into the heat exchanger of the furnace wall about 7"-11"

fan and limit

It is usually silver and about the size of a package of ciggarettes. This cover pulls off anf MAY say Honrywell on it. It would be mounted on the face of the furnace .
