The transformer steps down line voltage from 120V to 24V AC to power the low-voltage control circuit — including the thermostat, contactor coil, and control board. When this component fails, the entire control system goes dark: your thermostat becomes unresponsive, relays won't energize, and the unit will not start in any mode. A failed transformer is one of the most commonly overlooked causes of a completely non-functional HVAC system.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | Primary: 120V AC | Secondary: 24V AC | OEM part number HT01BD702 | Designed for low-voltage control circuit applications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier transformer built to exact VA and voltage tolerances.
