The transformer converts 120V line voltage down to 24V AC to power all low-voltage control circuit components — including the thermostat, control board, gas valve, and inducer relay. When this part fails, the furnace will appear completely unresponsive: the thermostat goes blank, the board shows no activity, and nothing operates. A failed transformer is one of the most common root causes of a total no-heat, no-response condition. OEM part number HT01BC116 has been superseded by the current factory replacement \u003cstrong\u003eHT680054\u003c\/strong\u003e, which ships in a Carrier factory-authorized parts box and is a direct drop-in replacement.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input: 120V AC | Output: 24V AC | VA Rating: 40VA | Frequency: 60Hz | Mounting: Foot mount | Connection: Wire leads with insulated female connectors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact factory VA tolerances, protecting downstream components like the control board and gas valve from voltage fluctuations.
