The transformer converts 120V line voltage to the 24V AC signal required to power the control board, thermostat circuit, and all low-voltage safety controls. When this component fails, the entire control circuit goes dark — your thermostat shows no response, the furnace won't fire, and no fault codes are generated because the board itself has no power.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V primary input | 24V secondary output | 40VA rating | Direct OEM replacement for part number HT01BC116 | Factory-matched terminal configuration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier transformer built to exact VA and impedance specifications.
