The flame sensor — also called a flame rod — is a safety component that detects the presence of a burner flame by passing a small micro-amp current through the flame to ground. When the sensor becomes coated with oxidation or carbon buildup, its ability to pass that current degrades. The furnace control board interprets this as a \"no flame\" condition and shuts down the gas valve, resulting in the classic symptom: the burner ignites normally, runs for 5–8 seconds, then shuts off — repeating up to three times before locking out entirely.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 48GS400192 | Manufactured to exact Carrier factory specifications | Direct drop-in replacement — no modification required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is precision-matched to the PY3PEA060090NB's control board micro-amp threshold. Generic sensors may have differing rod geometry or coating tolerances that cause nuisance lockouts even after cleaning.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Turn off gas and power at the breaker before servicing. Tools needed: 1\/4\" hex driver or nut driver, fine steel wool or emery cloth (to lightly clean rod if reusing), multimeter to verify micro-amp signal post-install.
