The transformer steps line voltage (120V) down to 24VAC to power the entire low-voltage control circuit — including the thermostat, contactor coil, and control board. When this component fails, absolutely nothing in the control circuit responds: the thermostat goes blank, the system won't call for heating or cooling, and no fault codes appear on the board because even the board loses its control power.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA capacity | Primary: 120VAC | Secondary: 24VAC | Class 2 rated | Factory-matched OEM part number HT01BC116\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM transformer is wound to exact factory VA and voltage specifications.
