The transformer steps down 120V line voltage to the 24V AC signal that powers your thermostat circuit, control board, gas valve, and all low-voltage components. When this part fails, the furnace will appear completely unresponsive — the thermostat goes dark, no ignition sequence initiates, and no fault codes appear because the control board itself has no power. A blown transformer is often caused by a short in the low-voltage wiring, so always inspect the 24V circuit before installing a replacement.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input 120V AC | Output 24V AC | Typical 40VA rating | Factory-matched impedance and thermal protection | Direct OEM replacement for Carrier PG9YAA036080ACSS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is wound and rated to Carrier's exact factory specifications, ensuring proper VA output and built-in thermal overload protection.
