The transformer steps down line voltage from \u003cstrong\u003e120V to 24V\u003c\/strong\u003e to power the low-voltage control circuit — including the thermostat, gas valve, inducer, and control board. When it fails, the entire control system goes dark: the thermostat loses power, the furnace will not respond to a heat call, and in some cases the system will blow a 3A control fuse repeatedly if a secondary short is present.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input 120V AC | Output 24V AC | 40VA rated | OEM part number HT01BC116 | Factory-matched windings and mounting footprint for drop-in replacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM transformer wound to exact factory VA and voltage tolerances.
