It converts 120V line voltage to 24V to power the entire low-voltage control circuit — including the thermostat, gas valve, inducer relay, and control board. When the transformer fails, nothing in the control system responds: the thermostat goes blank, the furnace won't call for heat, and no status codes appear on the board. A blown transformer is often the silent culprit behind what looks like a complete system failure.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input 120VAC | Output 24VAC | 40VA rating | Factory-matched OEM part number P201-35150 | Designed to meet original Carrier performance tolerances\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 specs.
