The transformer steps down line voltage (120V) to the 24V AC signal required to power the thermostat, control board, and all low-voltage system controls. When it fails, the entire control circuit goes dark — the thermostat becomes unresponsive, the furnace won't initiate any heating cycle, and there is no call-for-heat signal reaching the gas valve or inducer. Replacing this part with a genuine OEM unit restores factory-spec voltage regulation and protects downstream components.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V primary \/ 24V secondary | Factory-matched output tolerance | Designed for Carrier PG8MAA042090ACJA gas furnace control circuit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers (HT01BC116) are wound to exact VA and voltage tolerances.
