The transformer steps down 120V line voltage to the 24V signal voltage that powers your thermostat, control board, gas valve, and all low-voltage control circuits. When this component fails, the entire control system goes dark — the thermostat shows no power, the furnace won't respond to any calls for heat or cooling, and nothing operates. It is often the first component to check when a system is completely unresponsive despite a confirmed power supply.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | Primary: 120V AC | Secondary: 24V AC | Factory-matched output for precise low-voltage circuit protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM transformer (HT01BC116) is wound and tested to Carrier's exact VA and voltage tolerances, ensuring your control board and gas valve receive clean, stable 24V.
