The transformer steps line voltage (120V) down to the 24V signal voltage required by the thermostat, control board, gas valve, and all low-voltage control circuitry. When the transformer fails, the entire control circuit loses power — the thermostat goes blank, the furnace won't respond to any call for heat or cooling, and no diagnostic fault codes will even appear. A blown fuse on the secondary side is often the first sign of transformer trouble.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | Primary: 120VAC | Secondary: 24VAC | OEM part number HT01BC116 | Factory-matched output for stable 24V control circuits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact VA and voltage tolerances required by the Carrier control board.
