OEM Carrier Flame Sensor 50HJ401431 for Model PY1RPA060115AAWA

This is the OEM factory-specified flame sensor (part number 50HJ401431) for the Carrier PY1RPA060115AAWA gas furnace. The flame sensor — also called a flame rod — is a critical safety component that detects the presence of a burner flame by passing a small microamp current through it. When the sensor detects flame, it signals the control board to keep the gas valve open. A failed or coated flame sensor causes the furnace to light, run briefly for 5–8 seconds, and then shut down in a safety lockout — often repeating two or three times before the system locks out completely.

• Specs: OEM part number 50HJ401431 | Factory-matched microamp detection threshold | Correct rod length and mounting bracket geometry for direct drop-in fit
• OEM vs Generic: The OEM sensor is built to Carrier's exact electrical tolerances, ensuring reliable microamp signal detection. Generic aftermarket sensors may use inferior rod alloys that oxidize faster, leading to premature coating and repeat failures within one to two heating seasons.
• Install Difficulty: 2/5 — Turn off gas supply and disconnect power before servicing. Tools needed: 1/4" nut driver or flat-head screwdriver, fine steel wool or emery cloth (to clean existing rod if reusing bracket), and a multimeter to verify microamp draw post-install. Always confirm the gas valve closes before removing the sensor.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed by 3 PM local time ship same business day from our warehouse.
