The transformer steps down high-voltage line power (120\/208\/240 VAC) to the safe low-voltage signal (12\/24V) that energizes your control board, thermostat, and all 24V accessory circuits. When this transformer fails, the result is immediate and total: the thermostat goes dark, the furnace won't respond to any call for heat or cooling, and the control board loses all power. A failed transformer is often misdiagnosed as a board failure — always test the transformer first.\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 | 60 Hz | Single-phase | CSA listed | Totaline\/Carrier factory part\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is wound to exact Carrier factory tolerances, ensuring a stable 24V output that won't under-drive the control board or overheat under peak load.
