The transformer steps down line voltage from 120V AC to 24V AC to power the low-voltage control circuit — including the thermostat, contactor coil, and control board. When this component fails, the entire control circuit goes dead: the thermostat goes blank, the system won't respond to any calls for heating or cooling, and no fault codes will display because the board itself has lost power.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input 120V AC | Output 24V AC | 40VA rating | OEM part number HT01BD242 | Factory-matched to Carrier HGRH50HJ441645 control circuit requirements\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM transformer is wound and rated to exact Carrier factory specifications.
