The transformer converts incoming line voltage (120\/208\/240 VAC) down to 12\/24 VAC to power the system's control board, thermostat, and all low-voltage control circuits. When it fails, the entire control circuit loses power — resulting in a completely unresponsive thermostat, a system that won't start, or tripped low-voltage fuses that keep blowing without an obvious cause.\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 | 60 Hz | Single-phase | 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-authorized part (P201-35150), engineered to exact VA and voltage tolerances.
