The transformer steps down 120V line voltage to the 24V AC that powers your furnace's control board, thermostat circuit, and safety relays. When this component fails, the entire low-voltage control system goes dark — your thermostat won't respond, the furnace won't ignite, and no diagnostic codes will display. It is one of the most overlooked root causes of a completely unresponsive system.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V primary input | 24V secondary output | 40VA rated | Direct OEM replacement for part number \u003cstrong\u003eHT01BC116\u003c\/strong\u003e | Factory-matched lead configuration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is wound and encapsulated to Carrier's exact VA and impedance tolerances.
