The transformer steps down line voltage to power the 24V control circuit that drives your thermostat, contactor coil, gas valve, and every other low-voltage component in the system. When it fails, the entire control circuit goes dead — your thermostat goes blank, your system won't respond to any call for heat or cooling, and you may blow a low-voltage fuse repeatedly.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 230V primary voltage | 115V secondary voltage | OEM-matched mounting footprint | Cross-references: 320659-301, 2-05757-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This genuine Carrier OEM transformer is wound to exact factory tolerances, ensuring consistent 24V output under full load.
