The transformer steps down incoming 120V line voltage to the 24V signal voltage that powers your thermostat, control board, and all low-voltage control circuits. When this component fails, the entire control system goes dark — the thermostat goes blank, no heating calls are processed, and the furnace will not fire under any condition. A failed transformer is often misdiagnosed as a bad control board, making it the smart first component to test and replace.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rated | 120V primary \/ 24V secondary | Factory-matched OEM tolerances | Replaces OEM part number HT01BC116\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This factory OEM transformer is wound to exact VA and voltage specifications for the GB1AAV060135ADJA.
