The transformer steps down line-voltage power (115, 208, or 230V primary) to a safe 24V AC signal used by the control board, thermostat, and all low-voltage switching components. When this transformer fails, the entire control circuit goes dead — the thermostat goes blank, no relays pull in, and the system will not respond to any call for heating or cooling.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 60VA power rating | 115\/208\/230V AC primary | 24V AC secondary | 50\/60 Hz | Foot-mount configuration | Factory-matched Carrier RCD (Factory Authorized Part)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part, manufactured to exact VA and voltage tolerances.
