The control transformer steps down 115\/208\/230V line voltage to a safe 24V AC signal that powers the thermostat, contactor coils, control boards, and all low-voltage control circuitry. When it fails, the entire control circuit loses power — nothing responds to the thermostat, the unit will not start, and you may read zero volts on the 24V secondary terminals. A failed transformer is one of the most overlooked root causes of a completely unresponsive HVAC system.\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 design | OEM part number: HT01AW229\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part — engineered to exact VA and voltage tolerances.
