The transformer steps down 120V line voltage to the 24V AC signal that powers your thermostat, control board, and all low-voltage system controls. When the transformer fails, the entire control circuit goes dead — your thermostat goes blank, the system won't respond to any commands, and nothing operates. A failed transformer is often misdiagnosed as a bad control board, so always test transformer output voltage first before replacing more expensive components.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | Primary: 120V AC | Secondary: 24V AC | OEM part number HT01CN236 | Factory-matched for Carrier FE5ANB004000ABAA air handlers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact VA and voltage tolerances required by the Carrier control board.
