The transformer steps down high-voltage line power (115, 208, or 230V) to the 24V AC signal that energizes the entire low-voltage control circuit — including the thermostat, contactor coil, and any safety boards. When this part fails, the entire control circuit goes dark: the thermostat loses power, the unit refuses to start, and no fault codes can be read from the board. It is often the first component to inspect when a system is completely unresponsive.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 60 VA power rating | 115\/208\/230V AC primary | 24V AC secondary | 50\/60 Hz | Foot-mount configuration | OEM Part# HT01AW229\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a Factory Authorized Part built to Carrier's exact VA rating and insulation class.
