The transformer steps down 120V line voltage to 24V AC, powering the thermostat, control board, contactor coil, and all low-voltage control wiring throughout your system. When this component fails, the entire control circuit goes dark — the thermostat loses power, the system refuses to respond to any calls for heating or cooling, and in many cases the control board itself appears dead. A failed transformer is one of the most commonly misdiagnosed faults in air handler service calls.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rated | Primary: 120V AC | Secondary: 24V AC | Factory-matched OEM design | Compatible with standard 24V thermostat and control board circuits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is wound and rated to Carrier's exact factory tolerances, ensuring stable 24V output under full VA load.
