The transformer steps down 120V line voltage to 24V AC to power the furnace's low-voltage control circuit — including the thermostat, control board, gas valve, and safety switches. When this transformer fails, the entire control system goes dark: the thermostat loses power, the furnace will not initiate a heat cycle, and no error codes will display. A failed transformer is one of the most common causes of a completely unresponsive furnace.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V primary | 24V \/ 12V secondary | 40VA power rating | Also cross-references HT01CN001A, HT01BJ115, 19EA41612, 19EA42612\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is factory-wound to exact voltage and VA tolerances required by the Carrier UPFLOW200UA14B control board.
