It converts 120V line voltage to the 24V AC signal that powers your thermostat, gas valve, inducer relay, and all low-voltage control board functions. When this transformer fails, the entire control circuit goes dead — your furnace will not respond to the thermostat, the inducer won't energize, and no ignition sequence will begin. If you're measuring 0V between the R and C terminals on your control board, a failed transformer is the likely culprit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input 120V AC | Output 24V AC | 40VA rating | 60Hz | Foot-mount configuration | Wire lead connections — factory-matched to OEM specification\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM-grade replacement (superseded part HT680054) that ships in a Carrier\/Bryant factory-authorized parts box.
