The transformer converts 120V line voltage down to 24V AC to power the low-voltage control circuit — including the thermostat, gas valve, inducer relay, and control board. When it fails, the furnace goes completely silent: the thermostat shows no response, the inducer never starts, and no error codes appear because the control board itself has no power. A failed transformer is one of the most common \"nothing works\" diagnoses in residential gas furnaces.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA capacity | 120V primary input | 24V secondary output | 60 Hz single-phase | Foot-mount bracket | Wire lead connections with insulated female quick-connects\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is wound to exact Carrier factory tolerances, ensuring stable 24V output under full load.
