The control circuit transformer steps down line voltage from 120V to 24V to power the thermostat, control board, gas valve, and all low-voltage control components. When this transformer fails, the entire control circuit goes dark — the thermostat loses power, nothing responds, and the system will not heat or cool regardless of thermostat input.\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 HT01BC116 | Factory-matched for Carrier GA2AAD060090ABJA\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 spec.
