It converts 120V line voltage to the 24V signal required to power the control board, thermostat, contactor coil, and all low-voltage safety circuits. When the transformer fails, the entire control circuit goes dead — the thermostat shows no power, the unit won't respond to any call for heating or cooling, and you may detect a burning odor or see a blown fuse on the secondary side.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V primary \/ 24V secondary | OEM part numbers HT01BD236 and HT01BD702 | Factory-matched output tolerance for reliable control circuit operation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound and potted to Carrier's exact VA rating and insulation class.
