It steps down incoming line voltage from 120\/208\/240 VAC to a safe 12\/24 VAC output to power your system's control board, thermostat, and all low-voltage control circuits. When this transformer fails, the entire control circuit loses power — symptoms include a completely unresponsive thermostat, a furnace that won't start at all, or a blown 3-amp fuse on the control board caused by a secondary circuit short.\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 | Part # P201-35150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier\/Totaline factory-authorized transformer wound to exact VA and voltage tolerances.

Verify primary voltage matches your supply (120V or 240V tap) before ordering. If your control board fuse blew along with the transformer, inspect all low-voltage wiring for shorts before installing the new part. Questions about fitment?
