Its primary function is to step down line voltage from \u003cstrong\u003e120V AC to 24V AC\u003c\/strong\u003e, powering the low-voltage control circuit that operates the thermostat, gas valve, inducer, and all safety controls. When this transformer fails, the entire control circuit loses power — resulting in a completely unresponsive furnace with no thermostat communication, no ignition sequence, and no error codes displayed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA output rating | 120V primary \/ 24V secondary | OEM part number HT01BC116 | Factory-matched form, fit, and function for direct drop-in replacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM transformer is wound to Carrier's exact impedance and VA specifications, ensuring reliable 24V output under full control-circuit load.
