Mounted inside the furnace cabinet, it steps down the 120-volt line voltage to the 24-volt AC signal that powers the thermostat, gas valve, inducer relay, and all other low-voltage control circuit components. When it fails, absolutely nothing responds — the thermostat goes dark, the inducer won't start, and there are no error codes because the control board itself has lost power. A failed transformer is one of the most commonly misdiagnosed \"dead furnace\" causes.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V AC primary | 24V AC secondary | 60Hz | Wire lead connections | Foot-mount configuration | Replaces OEM part numbers HT01BC116, HT01BC116B, HT01BC115, HT01BB126, HT01CT120, HT01BC120, HT680054\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM-grade factory replacement.
