The transformer steps down 120V line voltage to the 24V signal required by the thermostat, control board, and all low-voltage components. When this part fails, absolutely nothing in the control circuit responds — the thermostat goes dark, no heating or cooling calls are processed, and the system sits completely dead despite power being present at the unit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V primary \/ 24V secondary | Factory OEM part number \u003cstrong\u003eHT01BC208\u003c\/strong\u003e | Exact factory mounting footprint and terminal configuration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e The OEM HT01BC208 transformer is wound to Carrier's exact VA rating and insulation class, ensuring the control board and thermostat receive stable, clean 24V power.
