The transformer steps down high-voltage primary power — 208V, 240V, or 480V — to the 24VAC secondary voltage that energizes the entire low-voltage control circuit: thermostat signals, contactor coils, and control board logic. When this transformer fails, the result is total control loss — your thermostat goes dark, the system won't respond to any call for heating or cooling, and no staging or safety functions operate.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 75VA rating | Primary: 208\/240\/480V (50\/60Hz) | Secondary: 24VAC | Foot-mount configuration | Factory-matched tolerances for Carrier systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound and potted to Carrier's exact VA and voltage tolerances.
