It converts 120V line voltage to the 24V AC signal that powers the entire low-voltage control circuit — including the thermostat, contactor coil, and control board. When this transformer fails, the system goes completely unresponsive: the thermostat goes blank or shows no communication, and no heating or cooling function can be initiated. A blown transformer is often caused by a wiring short downstream, so always inspect the 24V circuit for faults before installing the new unit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input: 120V AC | Output: 24V AC | Rating: 40VA | OEM Part Number: HT01AW229 | Factory-matched construction for Carrier packaged units\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM transformer is wound to exact factory VA and voltage tolerances.
