The transformer converts 120V line voltage down to 24V AC to power the entire low-voltage control circuit — including the thermostat, gas valve, inducer relay, and control board. When this component fails, the system goes completely silent: the thermostat goes blank, no staging occurs, and the furnace will not respond to any call for heat. A blown fuse on the secondary side or a shorted control wire are the most common causes of transformer failure.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | Primary: 120V AC | Secondary: 24V AC | Factory OEM part number HT01BC116 | Direct plug-in connector for fast replacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM transformer is wound and rated to exact Carrier factory tolerances.
