The transformer steps down 120V line voltage to the 24V signal voltage required by your thermostat, contactor coil, and all low-voltage control components. When this transformer fails, the entire control circuit goes dead — the thermostat becomes unresponsive, the system will not energize, and no heating or cooling operation is possible.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | Primary: 120V AC | Secondary: 24V AC | Class 2 transformer | Factory OEM part number HT01BD236\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine Carrier OEM transformer, wound to exact factory VA and voltage specifications.
