The transformer steps down line voltage from 120V AC to 24V AC to power the low-voltage control circuit — including the thermostat, control board, gas valve, and all safety switches. When the transformer fails, the entire control system goes dark: the thermostat shows no power, the furnace will not respond to any call for heat, and no indicator lights illuminate on the control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V primary | 24V secondary | 40VA rated | Factory-matched OEM replacement | Part No. P201-35150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM part built to Carrier's exact VA rating and insulation class. Undersized or off-brand transformers can overheat under full control-circuit load, causing nuisance tripping or premature failure — especially when zone valves or multiple accessories are wired in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Disconnect power before servicing. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter. Confirm secondary output reads ~24–28V AC after installation before restoring full power.
