This genuine OEM control transformer (part #1173691) steps the line voltage down to 24V to power the entire low-voltage control circuit on the ICP/Heil/Tempstar WPG3302060RKB1 packaged unit. It includes the matching 24V barrier/terminal assembly (part #1176032). Every call for heat or cool depends on this transformer: it energizes the thermostat, control board, contactor coil, gas valve, and safety switches. When a transformer fails — usually from a shorted secondary, an overloaded contactor coil, or age — the unit goes completely dead with no thermostat response and no operation. Installing the correct 40VA factory transformer restores full control power.
