The transformer steps down line voltage from 115, 208, or 230V to 24V AC to power the unit's entire low-voltage control circuit — including the thermostat, contactor coils, and control board. When this transformer fails, \u003cem\u003enothing works\u003c\/em\u003e: the thermostat goes blank, the system won't respond to calls for heating or cooling, and fuses or breakers may trip. A failed transformer is one of the most commonly misdiagnosed HVAC faults — always verify output voltage at the secondary terminals with a multimeter before condemning a board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 60 VA power rating | Primary voltage: 115\/208\/230V AC, 50\/60 Hz | Secondary voltage: 24V AC | Foot-mount configuration | 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 (FAP).
