This transformer steps down 120V line voltage to the 24V AC signal that powers the thermostat, control board, and every low-voltage relay in your system. When it fails, the result is total control-circuit loss — the thermostat goes dark, the system does not respond to any call for heating or cooling, and no safety outputs can be energized. Replacing this transformer with the correct OEM unit is the fastest path back to full system operation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input: 120V AC | Output: 24V AC | VA Rating: 40VA (factory-matched) | OEM Part Number: HT01CN241 | Direct plug-in replacement — no field wiring modifications required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This listing supplies the genuine Carrier OEM transformer, wound and insulated to exact factory specification.
