The transformer steps down 120V line voltage to 24V AC to power the entire low-voltage control circuit — including the thermostat, gas valve, ignition board, and zone controls. When this transformer fails, the furnace goes completely silent: no ignition attempt, no inducer startup, and the thermostat display may go dark. A failed transformer is often misdiagnosed as a bad control board, making it the smart first component to test.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V AC primary | 24V AC secondary | 40 VA rating | 60 Hz | Foot-mount configuration | Wire-lead connections with pre-installed insulated female connectors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact VA and voltage tolerances required by the Carrier PG9MAA036060AEKA control circuit. Generic units often run off-voltage, causing nuisance lockouts, erratic thermostat behavior, or premature control board failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Always shut off power at the breaker and gas supply before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph and label all wire connections before disconnecting the old unit. Test output voltage (should read ~24–28V AC) after installation before restoring gas.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.
