The transformer converts 120V line voltage to 24V AC to power the entire low-voltage control circuit — including the thermostat, control board, and relay coils. When the transformer fails, the result is a completely unresponsive system: no thermostat display, no contactor pull-in, and no heating or cooling operation whatsoever. A shorted transformer will often blow the control fuse as well, so always inspect and replace the fuse when servicing this part.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V primary \/ 24V secondary | OEM part number HT01CN241 | Factory-matched output voltage within ±2% tolerance for reliable control circuit operation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound and rated to exact factory specifications, ensuring consistent 24V output under full load.
