The transformer steps down line voltage (120V) to the 24V AC signal that powers your thermostat, control board, contactor coil, and every other low-voltage control circuit in the system. When this component fails, the entire control circuit goes dead — nothing responds, the thermostat goes blank, and the unit will not start under any call for heating or cooling.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | Primary: 120V AC | Secondary: 24V AC | Class 2 control circuit transformer | Direct OEM replacement for part number HT01BD236\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM transformer wound to exact VA and voltage tolerances.
