The transformer steps down 120V line voltage to 24V AC, powering the low-voltage control circuit that operates your thermostat, gas valve, inducer, and all safety switches. When the transformer fails, the entire control circuit goes dead — your furnace will not respond to the thermostat, and no heating sequence will initiate. Note: OEM part number \u003cstrong\u003eHT01BC116\u003c\/strong\u003e has been superseded by \u003cstrong\u003eHT680054\u003c\/strong\u003e, which is the current factory-authorized drop-in replacement shipped in a Carrier factory parts box.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Primary Voltage: 120V AC | Secondary Voltage: 24V AC | VA Rating: 40VA | Frequency: 60 Hz | Phase: Single | Mounting: Foot-mount bracket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact factory VA and voltage tolerances, protecting downstream components like the control board and gas valve.
