The transformer steps down the incoming 120V line voltage to the 24V AC signal that powers your thermostat, control board, gas valve, and all low-voltage control circuits. When this component fails, the entire control circuit goes dark — the thermostat shows no response, the furnace will not heat, and no error codes appear because the board itself has no power to generate them.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V primary | 24V secondary | 40VA rating | Factory-matched OEM tolerances for the PG9MAA060100AFKA platform\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e The OEM HT01BC116 transformer is wound and rated to exact Carrier factory specifications.
