The transformer steps down 120V line voltage to 24V AC, powering the entire low-voltage control circuit — including the thermostat, contactor coil, and control board. When this component fails, the system goes completely unresponsive: the thermostat goes blank, the unit won't energize, and no fault codes appear because the control circuit itself has lost power.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V primary input | 24V AC secondary output | 40VA typical rating | Spade\/wire-lead terminations | Factory-matched replacement for Carrier PH3PPA060000AA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM transformer maintains the factory-specified VA rating and output voltage tolerance.
