It steps down 120V line voltage to the 24V AC signal that powers every low-voltage control circuit in your system — including the thermostat, control board, gas valve, and inducer relay. When this transformer fails, the entire low-voltage side of your furnace goes dark: the thermostat goes blank, nothing responds to a heat call, and the system won't attempt ignition at all.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input 120V AC | Output 24V AC | 40VA rated | 60Hz | Foot-mount configuration | Wire-lead connection | Integrated 3A fuse protection | Replaces OEM part number HT01BC116 (superseded by HT680054)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact factory VA tolerances, ensuring stable 24V output under full control-circuit load. Undersized or off-tolerance generic units can cause erratic board behavior, nuisance lockouts, or premature control board failure — one reviewer noted a generic unit would not mount correctly without modification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Always shut off power at the disconnect and breaker before servicing. Photograph all wiring connections before removing the old transformer. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, multimeter (verify 24V output after install). Check R-to-C terminals on the control board to confirm proper voltage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.

Note that OEM part number HT01BC116 has been superseded — this listing ships the current authorized replacement. Verify your existing transformer's input\/output voltage and VA rating against your unit's data plate before ordering.
