The Goodman B1370254 Stack Overtemp Limit Switch is a genuine OEM safety control designed for the Goodman GMNT060-3B gas furnace and compatible models. This normally-closed thermal switch monitors flue/stack temperature and cuts power to the burners if the furnace overheats, protecting the heat exchanger and preventing unsafe operation. If your furnace is short-cycling on high limit or failing to fire, a faulty overtemp switch is a common cause.
