The switch will automatically reset after the furnace cools off. If the furnace fails to operate, contact a qualified service agency. • Check the manual-reset limit switches located on the ends of the burner enclosure (See Fig. 2). If the furnace has experienced a high-temperature condition, due to inadequate combustion air, these switches will shut off the furnace.
