The transformer steps down 230V line voltage to the 24V signal used by your thermostat, control board, and all low-voltage safety circuits. When this component fails, the entire control circuit goes dark — your thermostat goes blank, the system won't respond to any calls for heating or cooling, and nothing turns on. Part number \u003cstrong\u003eHT01AW230\u003c\/strong\u003e ensures a direct factory fit with no modifications required.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 60VA rating | 230V primary input | 24V secondary output | Factory-matched OEM tolerances for stable, reliable low-voltage control power\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound and tested to Carrier's exact VA and voltage specifications.
