OEM Carrier Flame Sensor 50HJ401431 for Model PY1REA060074AAWB

This is the genuine OEM Carrier flame sensor (part #50HJ401431), factory-specified for the Carrier PY1REA060074AAWB packaged gas heating unit. The flame sensor — also called a flame rod — is a critical safety component mounted in the burner assembly. It uses electrical current rectification to confirm the presence of an active flame during each ignition cycle. When the sensor fails or becomes coated with oxidation residue, the control board cannot verify combustion, causing the burner to shut down within 5–8 seconds of ignition as a safety lockout. The result: a system that lights briefly then cuts out repeatedly, leaving occupants without heat.

• Specs: OEM Part #50HJ401431 | Stainless steel sensing probe | Alumina-coated rod for corrosion resistance | 24V AC control circuit compatible | Dimensions approx. 2.9" W × 4" D × 1.75" H | Weight: 0.09 lbs
• OEM vs Generic: This is a genuine Carrier OEM part — not a universal aftermarket substitute. OEM sensors are calibrated to the exact microamp threshold your control board expects, ensuring reliable flame confirmation and preventing nuisance lockouts caused by out-of-spec aftermarket rods.
• Install Difficulty: 2/5 — Turn off gas supply and 24V power before servicing. Tools needed: 1/4" hex or flat-blade screwdriver, needle-nose pliers, and a multimeter (to verify microamp signal post-install). Photograph wire connector orientation before removal. Lightly clean the mounting bracket if oxidized before seating the new sensor.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day when ordered by 3 PM local time.
