The transformer converts high-voltage line power — \u003cstrong\u003e120\/208\/240 VAC\u003c\/strong\u003e — down to a safe \u003cstrong\u003e12\/24 VAC\u003c\/strong\u003e output to energize your system's control board, thermostat, and all low-voltage control circuits. When a transformer fails, the entire control circuit loses power: the thermostat goes blank, contactors won't pull in, and the system will not respond to any call for heating or cooling. A failed transformer is often caused by a short in the secondary (24V) circuit — always inspect low-voltage wiring for shorts before installing the replacement.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 50 VA rating | Primary: 120\/208\/240 VAC multi-tap | 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, matched exactly to the VA rating and voltage taps required by the YAC36100YAC107AC.
