The transformer steps down 120V line voltage to 24V AC, powering the entire low-voltage control circuit — including the thermostat, gas valve, inducer relay, and ignition sequencing. When this transformer fails, the furnace goes completely unresponsive: no call-for-heat response, no blower activation, and no fault codes displayed. It is frequently the first component to inspect when a furnace appears totally dead with no obvious blown fuses.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V primary | 24V secondary | 40VA output rating | Factory-matched impedance and thermal protection | Replaces OEM part number HT01BC116\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is wound and rated to exact Carrier factory specifications.
