The transformer steps down line voltage (120V) to the 24V low-voltage signal used by the thermostat, control board, gas valve, and all safety circuits. When this part fails, the entire control circuit goes dead — the thermostat displays nothing, the furnace won't respond to any call for heat or cooling, and no diagnostic fault codes will appear because the board itself has no power.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V primary | 24V secondary output | 40VA rated | Class 2 transformer | Factory-matched OEM fitment for HT01CN001\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier transformer built to exact VA and voltage tolerances.
