The transformer steps down the 115\/208\/230V line-voltage supply to the 24V AC signal that powers your thermostat circuit, contactor coil, and all low-voltage controls. When it fails, the entire control circuit goes dead — no thermostat response, no compressor engagement, and no fan operation. A blown transformer is often confirmed by a burning smell, a tripped internal fuse, or simply 0V on the secondary terminals with line voltage present at the primary.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 60 VA power rating | 115\/208\/230 VAC multi-tap primary | 24 VAC 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 Factory Authorized Carrier part, wound to exact VA rating and impedance specifications.
