The transformer steps down 120V line voltage to 24V AC to power the entire low-voltage control circuit — including the thermostat, gas valve, inducer relay, and control board. When it fails, nothing in the system responds: no call-for-heat, no fan, no ignition sequence. A blown transformer is often the first component to inspect when a furnace goes completely silent.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA capacity | 120V primary \/ 24V secondary | Compatible with standard R and C thermostat wiring | Matches OEM mounting footprint for drop-in replacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is wound to Carrier's exact VA rating and insulation class, ensuring stable 24V output under full control-circuit load. Generic transformers rated at nominal 40VA frequently sag under peak draw, causing nuisance lockouts and intermittent control faults.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Disconnect power at the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, multimeter (to verify 24V output post-install), wire nuts or spade connectors. Photograph existing wiring before disconnecting. Inspect low-voltage wiring for shorts before energizing — a shorted control wire will blow the new transformer immediately.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.
