The control transformer steps down line voltage from 120V to 24V to power the entire low-voltage control circuit — including your thermostat, contactor coil, gas valve, and control board. When this transformer fails, nothing in the system responds: the thermostat goes blank, the unit won't call for heating or cooling, and you may find a blown 3-amp fuse on the control board as a secondary symptom.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input 120V AC | Output 24V AC | 40VA rating | OEM part number HT01BC116 | Factory-matched impedance and thermal protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM transformer is wound to Carrier's exact VA rating and insulation class.
