The transformer steps incoming line voltage down from 120\/208\/240V AC to a safe 12\/24V AC to power your furnace's control board, thermostat circuit, and all low-voltage components. When this part fails, the entire control circuit goes dark — symptoms include a thermostat with no display, a furnace that won't respond to any call for heat, or a system that appears completely dead despite normal line voltage at the unit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 50VA rating | Primary: 120\/208\/240V AC | Secondary: 12\/24V AC | 60 Hz | Single phase | CSA listed | Totaline \/ Carrier Factory Authorized Part\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part (P201-35150) manufactured to factory tolerances.
