The transformer steps down 230V line voltage to the 24V signal that powers your thermostat, control board, and all low-voltage switching circuits. When this component fails, the entire control circuit goes dark — your thermostat will appear dead, the system won't respond to any commands, and nothing will operate even if the line voltage supply is intact.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 60VA capacity | 230V primary \/ 24V secondary | Factory-matched OEM part number HT01AW230 | Designed for continuous low-voltage control duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM transformer is wound to exact Carrier factory tolerances, ensuring stable 24V output under full VA load.
