The transformer converts 120V line voltage to the 24V AC signal that powers every low-voltage control circuit in your system — including the thermostat, gas valve, inducer relay, and control board. When this component fails, the entire control circuit goes dark: the thermostat goes blank, the furnace won't respond to heat calls, and in some cases the system will blow a low-voltage fuse repeatedly. Note: OEM part number HT01BC116 has been superseded by the current factory part number \u003cstrong\u003eHT680054\u003c\/strong\u003e — this listing ships the current OEM replacement, which is a direct drop-in fit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V primary | 24V secondary | 40VA rating | 60 Hz single-phase | Foot-mount configuration | Wire lead connections with pre-installed insulated connectors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact factory VA ratings and voltage tolerances. Undersized or off-spec generic units can starve the control board under peak load, causing nuisance lockouts or premature board failure — a repair far more costly than the transformer itself.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Turn off power at the breaker and verify 0V with a multimeter before touching any wiring. Tools needed: flathead and Phillips screwdrivers, multimeter, needle-nose pliers. Photograph all wire connections before disconnecting.
