The transformer steps down line voltage from 120V AC to the 24V AC signal used by your thermostat, control board, gas valve, and other low-voltage components. When this part fails, the entire control circuit goes dead — your thermostat will appear blank or unresponsive, and the furnace will not attempt ignition at all. A failed transformer is often overlooked during troubleshooting but is one of the most common causes of a completely non-responsive furnace.\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 | Factory-matched for Carrier GB3AAV060135AFJA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is wound to exact factory VA and voltage tolerances, ensuring reliable 24V signal delivery.
