The transformer converts 120V line voltage to the 24V AC low-voltage signal that powers your thermostat, gas valve, inducer relay, and control board. When the transformer fails, the entire low-voltage control circuit goes dead — you'll see no thermostat response, no inducer startup, and no heat output whatsoever. This is one of the most commonly overlooked components during a no-heat diagnostic.\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 | Compact 3\" L × 2-2\/16\" W × 2\" H footprint\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM transformer ships in a Carrier factory-authorized parts box and meets exact VA and voltage output tolerances. Generic transformers can output slightly off-spec 24V, stressing control boards and gas valves. OEM is always the safer choice for furnace control circuits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Turn off power at the disconnect before starting. Tools needed: flathead screwdriver, needle-nose pliers, multimeter. Label all wire leads before disconnecting. Check voltage between C and R terminals on the control board after installation to confirm 24V output.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM manufacturer warranty.
