The transformer converts high-voltage line power (120\/208\/240 VAC) down to the safe 24V control-circuit voltage required by your thermostat, control board, relay coils, and other low-voltage components. When this transformer fails, the entire control circuit loses power — you'll see a blank thermostat display, no response to heating or cooling calls, or a blown fuse on the control board with no apparent cause. Replacing it with the genuine OEM part (P201-35150) restores exact factory voltage regulation and protects all downstream electronics.\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 | Round foot-mount housing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact factory VA and voltage tolerances, ensuring stable 24V output under load.
