The transformer converts 120\/208\/240V line voltage down to a safe 12\/24V AC signal that powers your system's control board, thermostat, and all low-voltage control circuits. When this transformer fails, the entire control circuit goes dead — your thermostat becomes unresponsive, the system won't call for heating or cooling, and no safety or diagnostic functions can operate. If your unit has 24V present at the transformer primary but nothing at the secondary, this is your part.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 50VA rating | Primary: 120\/208\/240 VAC multi-tap | Secondary: 12\/24V AC | 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 factory-authorized Carrier\/Totaline part (P201-35150) built to exact VA and voltage tolerance specs.
