OEM Carrier Flame Sensor Rod for Model PY1RJA060074AAWA (Part# 50HJ401431)

This is the factory OEM replacement flame sensor for the Carrier PY1RJA060074AAWA packaged unit. The flame sensor — also called a flame rod — is a critical safety component mounted in the burner assembly. It generates a small micro-amp electrical signal in the presence of a flame, confirming to the control board that combustion is occurring. When the sensor becomes coated with oxidation or carbon buildup, or the rod itself fails, the control board cannot verify a flame and shuts off the gas valve within 5–8 seconds of ignition as a safety precaution. The result is a furnace that lights briefly, then locks out — often repeatedly — leaving the home without heat.

• Specs: OEM Part Number 50HJ401431 | Single-rod flame sensing element | Factory-spec micro-amp output | Ceramic insulator and stainless steel rod construction
• OEM vs Generic: This is the genuine Carrier OEM part, manufactured to exact factory tolerances for signal sensitivity and rod geometry. Generic sensors can have inconsistent micro-amp output, causing nuisance lockouts or failure to prove flame even when the burner is operating correctly.
• Install Difficulty: 2/5 — Shut off gas and power to the unit before servicing. Tools needed: 1/4" or 5/16" nut driver, fine steel wool or emery cloth (to clean rod if reusing), multimeter (to verify micro-amp output post-install). Disconnect the wire harness, remove the single mounting screw, swap the sensor, and reconnect. Always verify flame signal reading (1.5–4 µA typical) after installation.
• Warranty: 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse.
