The transformer steps down 120V line voltage to 24V AC to power the entire low-voltage control circuit — including the thermostat, gas valve, inducer controls, and control board. When it fails, the thermostat goes completely dark, nothing responds, or the system trips a fuse repeatedly. Replacing the transformer is one of the first diagnostic steps any technician takes on a fully non-responsive furnace.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V primary → 24V secondary | 40VA rating | Factory-matched terminals | Meets OEM insulation and thermal rating standards\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier part (HT01BC116), manufactured to exact factory specifications.
