Its job is critical: it steps high-voltage line power (120, 208, or 240 VAC) down to a safe 24V AC signal that powers the control board, thermostat circuit, and all low-voltage switching logic. When this transformer fails, the entire control circuit goes dead — the system will not respond to thermostat calls, contactors won't energize, and in many cases the unit appears completely inoperative with no error codes displayed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 50VA rating | Primary voltage: 120\/208\/240 VAC multi-tap | Secondary voltage: 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 genuine Carrier\/Totaline factory part with tight VA tolerance and CSA certification.
