It converts 120V line voltage to 24V AC, powering every low-voltage component in your system — thermostat, gas valve, inducer relay, and control board. When the transformer fails, the furnace goes completely silent: no ignition attempt, no blower response, no thermostat communication. OEM part number \u003cstrong\u003eHT01BC116\u003c\/strong\u003e has been superseded by Carrier's updated replacement \u003cstrong\u003eHT680054\u003c\/strong\u003e, which ships in a factory-authorized Carrier parts box and drops in without modification.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Primary voltage 120V AC | Secondary voltage 24V AC | 40VA rating | 50\/60 Hz single-phase | Foot-mount configuration | Wire lead connections with insulated female quick-connects\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact VA and voltage tolerances. Under-rated generic units can overheat, blow fuses repeatedly, or damage the IFC control board — costing far more than the transformer itself.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Shut off power at the disconnect and breaker before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (verify 0V before touching terminals). Photograph all wire connections before removal. Check the low-voltage fuse (typically 3A) on the control board — a failed transformer often blows it, and it must be replaced at the same time.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM manufacturer warranty.
