The transformer steps down 120V line voltage to the 24V AC signal that powers your thermostat, control board, gas valve, and all low-voltage safety circuits. When this component fails, the entire control circuit goes dead — the furnace will not respond to the thermostat, will not attempt ignition, and will show no signs of life at the board. A failed transformer is one of the most commonly overlooked causes of a completely non-responsive furnace.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V primary \/ 24V secondary | 40VA output rating | Foot-mount configuration | OEM part number HT01BC117 (superseded by HT680056) | Cross-reference: BE161840GDD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM transformer is wound and encapsulated to Carrier's exact factory specification, ensuring correct impedance, thermal protection, and VA headroom.
