The transformer steps down 120V line voltage to the 24V signal voltage that powers your thermostat, control board, and all low-voltage switching circuits. When this component fails, the entire control circuit goes dead — your thermostat goes blank, the system won't respond to any commands, and no heating or cooling operation is possible.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | Primary: 120V AC | Secondary: 24V AC | Direct OEM replacement | OEM Part Number: HT01AW229\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This factory OEM transformer is wound to exact VA and voltage specifications for the CH13NA06000GAAAA.
