The transformer converts 120V line voltage down to 24V to power the low-voltage control circuit — including your thermostat, gas valve, inducer relay, and control board logic. When it fails, nothing in the low-voltage circuit responds: the thermostat goes blank, the furnace won't call for heat, and the system appears completely dead even with 120V line power present.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V primary \/ 24V secondary | 60Hz | Step-down design | OEM part number 322666-701 | Also cross-references HT01BC115C, 4600-01V04K28\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Factory Authorized Part built to Carrier's exact VA and voltage tolerance specifications.
