The transformer converts 120V line voltage down to 24V AC, powering the entire low-voltage control circuit — thermostat, gas valve, inducer relay, and control board. When it fails, nothing in the system responds: no call-for-heat, no blower command, and no ignition attempt. A blown transformer is often caused by a shorted low-voltage wire or a failed downstream component, so always check the 24V circuit before installing the replacement.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V AC primary | 24V AC secondary | 60 Hz | Foot-mount configuration | Wire-lead connections with insulated female connectors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a factory-matched OEM transformer built to Carrier's exact VA and voltage tolerances.
