The transformer steps line voltage (120V) down to 24V AC to power the low-voltage control circuit — including the thermostat, contactor coil, gas valve, and control board. When the transformer fails, absolutely nothing in the control system responds: the thermostat goes blank, the system won't call for heating or cooling, and you may detect a burning smell or a tripped secondary fuse.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | Primary: 120V AC | Secondary: 24V AC | OEM part number HT01BC116 | Mounts to standard bracket inside unit control section\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM transformer is wound to exact Carrier factory specifications, ensuring proper VA capacity and thermal protection.
