The transformer steps down high-voltage primary power (115, 208, or 230VAC) to the 24VAC secondary signal that energizes your thermostat, contactor coils, reversing valve solenoids, and all low-voltage control circuits. When this transformer fails, the entire control circuit goes dark — you'll see a completely unresponsive thermostat, no contactor pull-in, and no system operation even though line voltage is present at the unit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 60VA power rating | 115\/208\/230VAC primary | 24VAC secondary | 50\/60 Hz | Foot-mount configuration | OEM Part Number: HT01AW229\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part built to exact VA rating and insulation class specs.
