The transformer steps down line voltage (120V) to the 24V AC signal that powers your thermostat, control board, gas valve, and all low-voltage safety circuits. When this component fails, the entire control circuit loses power — the result is a completely unresponsive system: the thermostat goes dark, the furnace will not fire, and no fault codes will appear because the board itself has no power to generate them.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V primary \/ 24V secondary | Class 2 control circuit transformer | Direct OEM factory replacement for part number HT01BD209\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e Carrier OEM transformers are wound and tested to exact VA and voltage tolerances.
