The transformer steps down 120V line voltage to 24V to power the entire low-voltage control circuit — including the thermostat, gas valve, contactor, and control board. When it fails, the entire system goes silent: the thermostat loses power, no heat call is ever generated, and nothing in the furnace responds. A failed transformer is often mistaken for a bad thermostat or control board, making correct diagnosis critical before replacement.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V primary | 24V secondary | 40VA rating | Factory-matched OEM construction | Spade or wire-lead termination as factory configured\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e The OEM HT01BC116 is wound and rated to exact Carrier factory specifications, ensuring stable 24V output under full control-circuit load.
