The transformer steps down 120V line voltage to 24V AC to power the low-voltage control circuit — including the thermostat, control board, gas valve, and ignition system. When this transformer fails, the entire control circuit goes dark: the thermostat shows no power, the furnace won't respond to any call for heat or cooling, and in some cases a tripped or blown 3A fuse on the board is the first clue.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V primary → 24V secondary | 40VA output rating | Factory-matched OEM replacement | Plug-and-play terminal connections for Carrier UPFLOW070US12A wiring harness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact VA and voltage tolerance specifications.
