The transformer steps down 120V line voltage to the 24V signal used by your thermostat, control board, contactor coil, and all low-voltage safety circuits. When the transformer fails, the entire control circuit goes dead — your thermostat goes blank, the system won't respond to any call for heating or cooling, and you may measure zero voltage on the 24V secondary terminals. It is one of the first components to check when nothing works at all.\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 HT01BC116 | Factory-matched to Carrier N6D48NG480201 control circuit requirements\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier transformer wound to exact VA and voltage tolerances.
