The transformer steps down the high-voltage supply (115V, 208V, or 230V primary) to the 24V AC signal that powers your thermostat, contactor coil, and all low-voltage control components. When this transformer fails, the entire control circuit goes dead — the thermostat becomes unresponsive, the unit won't energize on any call for heating or cooling, and you may find a blown 3A or 5A fuse on the control board as a secondary symptom.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 60VA power rating | 115\/208\/230V AC primary | 24V AC secondary | 50\/60 Hz | Foot-mount configuration | OEM part number HT01AW229 (also supersedes HT01AW229A)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part (FAP).
