The transformer steps down high-voltage line power (115, 208, or 230V primary) to the 24V AC signal that powers your thermostat, contactor coil, and all low-voltage control circuits. When this component fails, the entire control circuit goes dead — your thermostat goes blank, the system won't respond to any call for heating or cooling, and there may be a tripped circuit breaker or blown fuse on the secondary side. Replacing the transformer is one of the most impactful single-part repairs you can make to restore full system operation.\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 crosses to HT01AW229A)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This factory-authorized Carrier transformer is wound to exact VA and voltage tolerances.
