The transformer steps down line voltage from 120V to the 24V AC signal required to power the control board, thermostat, gas valve, and all low-voltage components in the system. When this transformer fails, the entire control circuit goes dead — the thermostat shows no response, the furnace won't initiate a call for heat, and no safety sequences can run. A failed transformer is often the first thing to check when a furnace appears completely unresponsive.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V primary input | 24V AC secondary output | Direct OEM replacement for part# HT01BC116 | Factory-matched construction and terminal configuration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is wound to Carrier's exact VA rating and insulation class, ensuring the 24V control circuit holds voltage under full load.
