The transformer converts 120V line voltage to the 24V signal required to power the humidifier's control circuit and solenoid valve. When this component fails, the humidifier will appear completely dead — no response at the thermostat humidistat call, no solenoid actuation, and no indication of power at the control board. It is one of the first components to check when the unit receives no low-voltage power.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | Input: 120V AC | Output: 24V AC | OEM part number P201-2201 | Factory-matched impedance and thermal protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM transformer is wound to Carrier's exact VA rating and insulation class, ensuring stable 24V output under load. Generic units often underrate VA capacity, causing voltage sag that leads to erratic solenoid behavior and premature control board failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Shut off power at the breaker before beginning.
