It converts 120V line voltage to the 24V signal that powers your thermostat circuit, control board, gas valve, and every other low-voltage component in the system. When this transformer fails, the entire control circuit goes dark — your furnace will not respond to the thermostat, the board will not sequence, and you will have a complete no-heat condition. It is one of the first components a technician checks on a dead-board call.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA capacity | 120V primary | 24V secondary | 60Hz | OEM part number 322666-701 | Superseded by Carrier HT680054 (same specs, direct fit)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact factory VA and voltage tolerances.
