The transformer converts 120V line voltage to 24V AC to power the entire low-voltage control circuit — including the thermostat, gas valve, inducer relay, and control board. When it fails, the system goes completely unresponsive: no thermostat display, no blower activity, and no ignition attempt. A failed transformer is one of the most overlooked root causes of a furnace that appears completely dead.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rated | 120V primary \/ 24V secondary | Factory-matched footprint and terminal configuration for direct OEM fit | Part Number: \u003cstrong\u003eHT01CN001\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM transformer built to exact VA and impedance specifications.
