The transformer converts 120V line voltage down to 24V to power the entire low-voltage control circuit — including the thermostat, gas valve, inducer relay, and ignition board. When it fails, absolutely nothing in the control system responds: no call for heat, no inducer start, no display — the furnace goes completely dark electrically. A blown internal fuse or shorted secondary winding are the two most common failure modes.\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 | Compact 3\" L × 2-3\/16\" W × 2\" H form factor | Wire lead connections\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is wound to exact Carrier factory tolerances, ensuring stable 24V output under full control-circuit load. Generic transformers with undersized VA ratings can sag under load, causing erratic lockouts, nuisance faults, and premature board failures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Shut off furnace power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter (to verify 24V output after install). Photograph all wire connections before removing the old transformer. Label leads if needed. Total job time: 20–30 minutes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM manufacturer warranty.
