The transformer steps down 120V AC line power to the 24V AC signal required by every low-voltage component in the system — including the thermostat, gas valve, inducer relay, and control board. When the transformer fails, the entire control circuit goes dark: the thermostat goes blank, the furnace won't respond to a call for heat, and no error codes appear because the board itself has lost power.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V AC primary (110–125V range) | 24V AC secondary | Foot-mount bracket | Wire lead connections with pre-installed insulated female connectors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a factory-authorized OEM replacement built to exact Carrier specifications.
