The transformer steps down 120V line voltage to the 24V AC signal that powers your thermostat, control board, gas valve, and all low-voltage control circuits. When this component fails, the furnace loses all communication with the thermostat — resulting in a completely unresponsive system, blown low-voltage fuse, or a furnace that won't call for heat at all. Replacing it is one of the most cost-effective repairs in HVAC service.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V primary voltage | 24V secondary voltage | 50\/60 Hz single-phase | OEM part HT01BC116 (superseded by HT680054)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound and rated to exact factory tolerances, ensuring stable 24V output under full control-circuit load.
