The transformer steps down incoming line voltage (120\/208\/240 VAC) to a safe 24V output that powers the system's control board, thermostat, and all low-voltage control circuits. When this transformer fails, the entire control circuit goes dark — symptoms include a completely unresponsive thermostat, a blank control board, or a furnace that won't fire under any call for heat. Replacing a failed transformer is one of the most decisive, cost-effective repairs in HVAC service.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 50 VA rating | Primary: 120\/208\/240 VAC | Secondary: 12\/24 VAC | Single-phase | 60 Hz | CSA listed | Dimensions: 3.8\" L × 3.1\" W × 2.2\" H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier\/Totaline factory part (P201-35150), manufactured to exact VA tolerance and insulation class.
