The transformer converts 120V line voltage down to 24V AC to power every low-voltage control circuit in your furnace — including the thermostat, inducer relay, gas valve, and ignition board. When the transformer fails, the entire furnace goes dark: no thermostat response, no ignition attempt, no heat. A blown transformer is often caused by a short in the 24V wiring circuit, so always inspect secondary-side wiring before installing the new unit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V primary \/ 24V secondary | 50\/60 Hz single-phase | Wire-lead connections with insulated female quick-connects | Compact foot-mount design (3″ L × 2-3\/16″ W × 2″ H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM transformer is wound to exact Carrier factory tolerances, ensuring stable 24V output under full VA load.
