The transformer steps down line voltage from 120V to 24V AC to power the low-voltage control circuit — including the thermostat, gas valve, inducer relay, and control board. When this component fails, the entire control system goes dark: the thermostat loses power, the furnace won't respond to any call for heat, and no status LEDs illuminate on the control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | Primary: 120V AC | Secondary: 24V AC | Factory OEM replacement for part number P201-35150 | Designed for Carrier upflow furnace applications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine OEM Carrier transformer, wound and tested to exact factory VA and voltage specifications.
