Originally sold under part number \u003cstrong\u003eHT01BC116\u003c\/strong\u003e, this transformer has been superseded by the current OEM part \u003cstrong\u003eHT680054\u003c\/strong\u003e — a direct, factory-authorized drop-in replacement. The transformer converts 120V line voltage to 24V AC, powering all low-voltage control circuit components including the thermostat, control board, gas valve, and inducer relay. When it fails, the entire control circuit goes dead: the furnace will not respond to the thermostat, no status codes will display, and nothing will operate.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input Voltage: 120V AC | Output Voltage: 24V AC | VA Rating: 40VA | Frequency: 60 Hz | Mounting Type: Foot mount | Connection: Wire leads | Includes 3A inline fuse protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact factory VA and voltage tolerances, ensuring stable 24V output under full control-circuit load. Generic units often run slightly low on output voltage, causing erratic board behavior, nuisance lockouts, and premature control board failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Shut off power at the breaker and confirm voltage is zero before proceeding. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph existing wiring before disconnecting. Check C and R terminals on the control board after installation to confirm 24V output.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty included.

OEM part HT01BC116 has been superseded by HT680054 — both numbers are cross-referenced and fulfilled with the current factory replacement unit. Also cross-references: HT01BC115, HT01BB126, HT01BC120, HT01AW115, and HT01CT120. Verify your unit's control voltage requirement is 24V before ordering. Need fitment confirmation?
