This genuine OEM 40VA control transformer (part number 1173691) steps line voltage of 208/230V down to the 24V control circuit on the ICP/Tempstar/Heil WPG3362060RKB1 furnace, and ships with the matching 24V barrier (part number 1176032). The transformer powers the thermostat, control board relays, gas valve, and other low-voltage components. When a transformer fails — usually from a control-circuit short, a seized contactor coil, or simple age — the entire 24V system goes dead, leaving the furnace completely unresponsive even though line voltage is present. A failed transformer often smells burnt, shows a blown internal fuse link, or reads zero volts on the secondary side. Replacing it with the correct OEM 40VA unit restores power to the control circuit and brings the system back online.
