The transformer converts 120V line voltage down to 24V AC to power the low-voltage control circuit — including the thermostat, gas valve, inducer relay, and control board. When this part fails, the entire control circuit goes dark: the thermostat goes blank, nothing responds to a call for heat, and the furnace will not attempt to start. Replacing it restores 24V to all downstream components immediately.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V Primary | 24V Secondary | 40VA Rating | 60 Hz | Single Phase | Foot-mount configuration | Wire lead connections with insulated female quick-connect terminals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier replacement (or direct OEM-authorized successor), manufactured to factory voltage and VA tolerances. Generic transformers are often rated at loose tolerances, risking under-voltage to sensitive control boards and premature failures — especially in multi-stage furnace applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Shut off power at the breaker and confirm 0V with a multimeter before touching any wiring. Label or photograph all wire connections before removal. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. After installation, verify 24V between R and C terminals on the control board before restoring full operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM manufacturer warranty.
