The transformer steps down 120V line voltage to the 24V signal voltage that powers your thermostat, control board, and all low-voltage system controls. When this part fails, the entire control circuit goes dead — the thermostat becomes unresponsive, the system won't call for heating or cooling, and no fault codes will even display. If you're measuring 120V on the primary side but zero volts on the secondary, this transformer is almost certainly the cause.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rated | 120V primary \/ 24V secondary | OEM part number HT01AW229 | Factory-matched to Carrier HC1CJX060000AAAA control circuit requirements\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact VA and voltage tolerances specified by Carrier engineering.
