The transformer steps down the unit's 208\/230V line voltage to the 24V low-voltage signal required to power the control board, thermostat, gas valve, and all relay circuits. When this part fails, the entire control circuit goes dark — the thermostat becomes unresponsive, the system won't call for heating or cooling, and no error codes may even display because the board itself has lost power.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA power rating | 208\/230V primary voltage | 24V secondary voltage | Class 2 control transformer | Foot-mount design | Approx. 1.25 lbs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part manufactured to exact factory tolerances.
