The transformer steps down 120V line voltage to the 24V control voltage required to power the thermostat circuit, control board, gas valve, and all low-voltage accessories. When this transformer fails, the entire control circuit goes dead — the thermostat displays nothing, the furnace won't respond to any call for heat or cooling, and no diagnostic fault codes will appear because the board itself has no power to operate.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V primary \/ 24V secondary | Factory OEM part number HT01BC116 | Designed to factory tolerance for the Carrier GB3AAV060115AGJA control circuit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact VA and voltage tolerances required by the furnace control board.
