The transformer steps down line voltage from 120\/208\/240 VAC to a safe 12\/24 VAC output, powering the furnace's control board, thermostat circuit, and all low-voltage components. When the transformer fails, the entire control circuit goes dark — symptoms include a completely unresponsive thermostat, no system response to calls for heat, or a tripped low-voltage fuse caused by a shorted secondary winding.\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 | 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 Carrier Factory Authorized \/ Totaline-branded OEM unit, engineered to exact VA and voltage tolerances for your furnace's control board.
