The transformer steps down 120V line voltage to 24V AC to power the entire low-voltage control circuit — including the thermostat, control board, gas valve, and ignition sequence. When this part fails, the furnace will appear completely unresponsive: no display, no call-for-heat reaction, and no ignition attempt whatsoever. A failed transformer is one of the most commonly misdiagnosed furnace faults, often mistaken for a bad control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input 120V AC | Output 24V AC | 40VA rating | Factory-matched OEM design | Spade or wire-lead termination per factory configuration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers from Carrier are wound to exact VA tolerances, protecting downstream components like the gas valve and IFC board from voltage fluctuations.
