OEM Carrier Flame Sensor 50HJ401431 for Model PY1RJA060115AAWB

This is the genuine OEM flame sensor (part #50HJ401431) factory-specified for the Carrier PY1RJA060115AAWB packaged gas heating unit. The flame sensor — also called a flame rod — is a safety-critical component that detects the presence of a live burner flame during the ignition sequence. It passes a small DC current through the burner flame to confirm combustion. When the sensor fails or becomes coated with oxidation, the control board receives no flame signal, triggers a safety lockout, and shuts off the gas valve — typically within 5 to 8 seconds of ignition. The result: a furnace or packaged unit that lights briefly, then goes out, cycling repeatedly without ever reaching setpoint.

• Specs: OEM part #50HJ401431 | Stainless steel sensing probe with alumina-coated rod | Dimensions approx. 2.9" W × 4" D × 1.75" H | Weighs approx. 0.09 lbs | Compatible with standard 24V AC furnace control circuits
• OEM vs Generic: This factory OEM sensor is calibrated to Carrier's exact microamp detection threshold. Generic sensors can exhibit looser tolerances, causing nuisance lockouts or, worse, delayed shutoff — creating a safety risk on a gas appliance. Always use OEM on gas combustion components.
• Install difficulty: 2/5 — Turn off gas supply and 120V power before servicing. Tools needed: 1/4" hex driver or nut driver, fine steel wool or light emery cloth (to clean rod if reusing), and a multimeter to verify microamp output. Photograph wire connector routing before removal.
• Warranty: 1-year OEM manufacturer warranty. In-stock orders ship same business day from our warehouse when ordered before cutoff.
