The transformer steps down line voltage (120V primary) to the 24V secondary signal used by your thermostat, control board, contactor coils, and all low-voltage safety circuits. When this transformer fails, the entire control circuit goes dead — your thermostat goes blank, the system won't respond to any call for heating or cooling, and you may find a blown fuse on the control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V primary \/ 24V secondary | Direct OEM replacement for Carrier part HT01AW229 | Factory-matched output tolerance for stable low-voltage control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to Carrier's exact VA and voltage specifications, ensuring your control board and thermostat receive a clean, stable 24V signal.
