The transformer reduces incoming line voltage to safe low-voltage power for the control board, thermostat, and all 24V control circuit components. When this part fails, the entire control circuit goes dark — symptoms include a completely unresponsive thermostat, a furnace that won't attempt ignition, or a blower motor that runs continuously with no heating cycle.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 50VA rating | Primary voltage: 120\/208\/240 VAC multi-tap | Secondary voltage: 12\/24V | 60 Hz | Single phase | CSA listed | Factory 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-authorized part — not a universal aftermarket substitute.
