It converts 120V line voltage down to 24V AC to power the entire low-voltage control circuit — including the thermostat, control board, gas valve, and zone controls. When the transformer fails, the result is total system silence: the thermostat goes blank, nothing responds, and you may measure 0V between the R and C terminals on the control board. This is a direct OEM replacement built to factory specifications, superseding the original part number \u003cstrong\u003eHT01BC116\u003c\/strong\u003e.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input 120V AC | Output 24V AC | 40VA rating | 60 Hz | Foot-mount configuration | Wire lead connections\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound and insulated to exact Carrier factory tolerances, ensuring stable 24V output under full load.
