The transformer steps line voltage down from 120V to the 24V AC signal that powers the thermostat circuit, control board, and all low-voltage controls. When this component fails, nothing in the system responds — the thermostat goes dark, the inducer never starts, and there is zero call for heat. A bad transformer is often misdiagnosed as a failed thermostat or control board, making proper diagnosis critical before replacing any other component.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input: 120V AC | Output: 24V AC | Capacity: 40VA | OEM Part Number: HT01BC116 | Factory-matched for Carrier PG8JAA024045ABJA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier transformer wound to exact factory VA and voltage specifications.
