The transformer converts 120V line voltage down to the 24V signal required to power the control board, thermostat circuit, and all low-voltage control components. When this part fails, the entire control circuit goes dead — your thermostat becomes unresponsive, the furnace won't initiate any heating cycle, and no diagnostic fault codes will appear because the board itself has no power to operate.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V primary \/ 24V secondary | Class 2 transformer | OEM part number HT01BC116 | Factory-matched for Carrier GB1AAV060155AEJA\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 voltage tolerances, protecting the control board from undervoltage or surge conditions.
