It converts 120V line voltage to 24V AC to power the entire low-voltage control circuit — including the thermostat, gas valve, inducer relay, and control board. When this transformer fails, the result is immediate and total: the thermostat goes dark, the furnace locks out, and nothing responds. No clicks, no ignition attempt, no blower — the system is completely dead.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V primary | 24V secondary | 40VA rated | Step-down class-2 transformer | Wire lead connections | Direct OEM replacement for HT01BC116 (current successor: HT680054)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact factory VA and voltage tolerances, protecting sensitive downstream components like the IFC control board.
