The transformer steps down 120V line voltage to the 24V signal voltage required to power the control board, thermostat, and all low-voltage switching circuits. When it fails, the entire control circuit goes dead — your thermostat becomes unresponsive, the contactor won't energize, and the system will not start at all, even though high-voltage power is present at the unit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input 120VAC | Output 24VAC | 40VA rating | Primary and secondary fuse protection | Designed for continuous-duty HVAC control circuits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e The OEM HT01AW229 transformer is wound to exact Carrier specifications, ensuring proper VA capacity and voltage regulation under varying load conditions.
