OEM Carrier Flame Sensor 50HJ401431 for Model PY1RPA060074AAWB

This is the genuine OEM Carrier flame sensor (part #50HJ401431) factory-specified for the Carrier PY1RPA060074AAWB packaged gas/electric unit. The flame sensor — also called a flame rod — is a critical combustion safety component. It passes a small microamp current through the burner flame to confirm ignition. When the sensor fails, the control board cannot verify that combustion has occurred, causing the system to shut off the gas valve within 5–8 seconds of ignition and ultimately lock out after 3 failed attempts. A dirty or cracked sensor is one of the most common causes of a no-heat call in commercial packaged units.

• Specs: Stainless steel sensing rod | Alumina-coated probe for corrosion resistance | Dimensions: approx. 2.9"W × 4"D × 1.75"H | Weight: 0.09 lbs | Compatible with standard 24V AC furnace control circuits
• OEM vs Generic: This genuine Carrier OEM sensor is factory-calibrated for exact microamp sensitivity. Generic flame sensors may read outside tolerance, causing nuisance lockouts or delayed shutoff — both safety and reliability risks in a commercial packaged unit.
• Install Difficulty: 2/5 — Disconnect power and gas before servicing. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers, multimeter (microamp setting to verify sensor signal after install). Lightly sand the rod with fine steel wool if reusing; replace if cracked or heavily oxidized.
• Warranty: 1-year OEM manufacturer warranty. In-stock units ship same business day when ordered by 3 PM local time.
