The transformer steps down line voltage (120V) to the 24V AC control circuit voltage required to power the thermostat, control board, and all low-voltage switching components. When the transformer fails, the entire control circuit goes dark — the thermostat loses power, the air handler won't respond to calls for heating or cooling, and in many cases nothing appears to happen at all when the system is energized. A failed transformer is one of the most commonly overlooked causes of a completely unresponsive 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 HT01CN241 | Factory-matched footprint for direct drop-in replacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact VA and voltage tolerances required by the Carrier control board.
