The transformer steps down high-voltage line power (115, 208, or 230V primary) to the 24V AC signal voltage that powers the entire control circuit — including the thermostat, contactor coil, reversing valve solenoid, and all safety controls. When this transformer fails, the result is total loss of control voltage: the thermostat goes blank, the system will not respond to any call for heating or cooling, and the unit sits completely silent despite line power being present.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 60VA capacity | Primary voltage: 115\/208\/230V AC | Secondary voltage: 24V AC | Foot-mounted 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, manufactured to exact VA rating, impedance, and thermal insulation class specifications.
