I don't think that this particular smoke unit has a thermistor. In the online photos of the PCB, there are no mountings for one. Also I think that it pre-dates the Legacy/Vision models that were equipped with thermistors.
Are you sure that somehow the smoke setting has not been set to "off"? Have you tried an engine reset per the manual?
