The transformer steps down 120V line voltage to 24V to power the entire control circuit — including the thermostat, contactor coil, and control board. When this component fails, nothing works: the thermostat goes blank, the system refuses to respond to any call for heating or cooling, and you may notice a burning smell or a tripped low-voltage fuse. If your system is completely unresponsive and all other components check out, this transformer is the first place to look.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V primary \/ 24V secondary | Factory-matched OEM design | Integral mounting bracket | Part number HT01CN236\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM transformer wound to exact VA and voltage tolerances.
