The transformer steps down incoming line voltage — 120, 208, or 240 VAC — to a safe 24V signal that powers the control board, thermostat circuit, and all low-voltage components. When this transformer fails, the entire control circuit goes dark: the system may show no response to thermostat calls, the blower may run continuously with no heat, or the unit may fail to start entirely.\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 | Factory-matched to Carrier UPFLOW100FAUHC12A control circuit requirements\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier\/Totaline factory-authorized part.
