The transformer steps down 120V line voltage to the 24V signal that powers the thermostat, control board, and all low-voltage safety circuits. When it fails, the entire control circuit goes dark — the thermostat goes blank, no call for heat is recognized, and the furnace will not attempt to start. If your Carrier GB3AAV060135AEJA appears completely unresponsive even with confirmed 120V power at the unit, a failed transformer is one of the first components to test.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA output rating | 120V primary \/ 24V secondary | Color-coded lead wires | Factory-matched impedance and VA rating for the GB3AAV060135AEJA control circuit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound and rated to exact factory specifications, ensuring consistent 24V output under full load.
