It converts 120V line voltage to the 24V AC signal that powers every low-voltage component in your system — the thermostat, gas valve, control board relays, and zone controls. When the transformer fails, the entire control circuit goes dead: the furnace won't respond to the thermostat, the board shows no life, and you may measure 0V between the R and C terminals on your control board. This is the correct OEM replacement to restore full operation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input 120V AC | Output 24V AC | 40VA rating | Foot-mount configuration | Wire lead connections | 60 Hz | Replaces OEM part HT01BC116 (superseded by HT680054)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM Carrier transformers are wound to exact factory VA and voltage tolerances, protecting sensitive control boards from under- or over-voltage.
