The transformer steps down the incoming 120\/208\/240V line voltage to a safe 12\/24V AC signal that powers your system's control board, thermostat wiring, and all low-voltage accessories. When this transformer fails, the entire control circuit goes dark — the thermostat loses communication, the system refuses to respond to calls for heating or cooling, and nothing runs. Replacing it restores all low-voltage control functions immediately.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 50VA rating | Primary: 120\/208\/240 VAC | Secondary: 12\/24 VAC | 60 Hz | Single-phase | CSA Listed | Totaline \/ Carrier OEM factory part\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is wound to exact factory VA and voltage tolerances, ensuring the control board and thermostat receive a clean, stable 24V signal.
