The transformer steps down 120V line voltage to the 24V AC signal that powers your thermostat, control board, and all low-voltage components. When this part fails, the entire control circuit goes dark — nothing responds, the thermostat goes blank, and the system will not heat, cool, or run the fan under any call.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | Primary: 120V AC | Secondary: 24V AC | Factory-matched OEM construction | Spade or screw terminal connections\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound and insulated to Carrier's exact VA and thermal specifications.
