The transformer steps the unit's 460V primary supply voltage down to a 230V secondary output at a robust 1564VA capacity, delivering reliable power to downstream controls, motors, and auxiliary circuits. When this transformer fails, you'll typically see a completely unresponsive unit — no thermostat response, no contactor pull-in, and no blower operation — because the downstream control voltage is lost entirely.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 460V Primary | 230V Secondary | 1564 VA Rating | OEM Part Number HT01BC701 | Also referenced as BE33426001\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Factory Authorized Parts transformer wound and tested to Carrier's exact VA rating and insulation class.
