The transformer converts 120V line voltage down to 24V AC to power all low-voltage control components — including the thermostat, gas valve, inducer relay, and integrated furnace control board. When this part fails, the entire low-voltage control circuit goes dead: the thermostat display may go blank, the furnace will not respond to a call for heat, and no diagnostic fault codes will appear because the board itself has no power to operate.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V primary (input) | 24V secondary (output) | 60 Hz single-phase | Wire lead connections with insulated female quick-connects | Dimensions: 3″ L × 2-3\/16″ W × 2″ H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM transformer wound to exact factory VA and voltage tolerances. Undersized or off-tolerance generic transformers can overheat under the combined load of a thermostat, gas valve, and control board — leading to repeated nuisance failures and potential low-voltage wiring damage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Always shut off power at the disconnect and breaker before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (verify 24V output after install). Photograph all wire connections before disconnecting. Check 24V between the R and C terminals on the control board to confirm correct operation after replacement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM manufacturer warranty.
