Its job is critical: it converts high-voltage line power (120, 208, or 240 VAC) down to a safe 12\/24 VAC used by the control board, thermostat, and all low-voltage safety circuits. When this transformer fails, the entire control circuit goes dark — you'll see a blank thermostat display, no response to heat calls, or a furnace that won't attempt ignition at all.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 50 VA rating | Primary voltage: 120\/208\/240 VAC | Secondary voltage: 12\/24 VAC | Single phase | 60 Hz | CSA listed | OEM part number P201-35150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier\/Totaline factory part.
