The flame sensor—also called a flame rod—is a critical combustion safety component. It detects the presence of a confirmed burner flame by passing a small microamp current through the flame to ground. When the sensor becomes coated with oxidation or carbon deposits, the control board can no longer verify flame and will shut off the gas valve within 5–8 seconds of ignition as a safety lockout. Replacing this sensor is one of the most common and cost-effective repairs in gas heating systems.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part #50HJ401431 | Stainless steel sensing rod with alumina ceramic insulator | Dimensions: approx. 2.9\" W × 4\" D × 1.75\" H | Compatible with 24V AC control circuits | Weight: 0.09 lbs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine Carrier OEM sensor, factory-calibrated to the exact microamp threshold required by your PY1REA120180ABWB control board. Generic sensors may have rod length or bracket angle variances that cause nuisance lockouts or incomplete flame signal readings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Turn off gas supply and 120V power before servicing. Tools needed: 1\/4\" hex driver or nut driver, needle-nose pliers, and a multimeter (to verify microamp signal 2–8 µA DC). Disconnect the single wire connector, remove the one mounting screw, swap the sensor, and reconnect. Always verify flame signal with a meter after install.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM manufacturer warranty.
