The transformer steps down 120V line voltage to 24V AC to power the low-voltage control circuit — including the thermostat, contactor coils, and control board. When this transformer fails, absolutely nothing works: the thermostat goes dark, no calls for heating or cooling are answered, and the entire system appears completely dead. A failed transformer is often misdiagnosed as a bad control board, making correct identification critical before replacing more expensive components.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V primary \/ 24V secondary | Single-phase | Direct OEM replacement for part number HT01CN241 | Factory-matched output for stable low-voltage control signal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM transformer meets Carrier's exact VA rating and insulation class.
