The transformer steps down incoming line voltage (120\/208\/240 VAC) to a safe 24V signal that powers your furnace's control board, thermostat circuit, and all low-voltage safety controls. When this transformer fails, the entire control circuit goes dark — resulting in a completely unresponsive thermostat, a blank control board, or a furnace that won't attempt ignition at all.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 50VA rating | Primary: 120\/208\/240 VAC | Secondary: 12\/24 VAC | Single phase | 60 Hz | CSA listed | Factory part number P201-35150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier\/Totaline OEM part, engineered to exact VA rating and impedance tolerances.
