OEM Carrier Flame Sensor 50HJ401431 for Model PY1RPA060115AAWB

This is the genuine OEM flame sensor (part #50HJ401431) factory-specified for the Carrier PY1RPA060115AAWB packaged gas heating unit. The flame sensor — also called a flame rod — is a critical safety component that uses flame rectification to confirm the presence of a burner flame after ignition. When the control board doesn't receive a valid signal from the sensor within a few seconds of ignition, it shuts off the gas valve as a safety precaution. A failed or carbon-fouled sensor is one of the most common causes of a furnace or packaged unit that lights briefly, then shuts down — typically cycling 3 times before locking out entirely.

• Specs: OEM part #50HJ401431 | Stainless steel sensing probe with alumina-coated tip | Dimensions: 2.9"W × 4"D × 1.75"H | Weight: 0.09 lbs | Compatible with standard 24V AC control circuits
• OEM vs Generic: This is a genuine Carrier OEM sensor calibrated to the exact factory rectification threshold. Aftermarket sensors can have inconsistent probe geometry or coating quality, leading to nuisance lockouts or missed flame events — always use OEM on gas appliances.
• Install difficulty: 2/5 — Turn off gas and power before starting. Tools needed: 1/4" or 5/16" hex driver, needle-nose pliers, and a multimeter (to verify microamp signal, typically 1–5 µA DC). Clean the old probe with fine steel wool before condemning it — oxidation buildup is a frequent culprit.
• Warranty: 1-year OEM factory warranty. In stock — ships same business day when ordered before cutoff.

Compatibility: Engineered as a direct OEM drop-in replacement for the Carrier PY1RPA060115AAWB packaged gas/electric unit. Verify part number on your unit's data plate or existing sensor lead before ordering. Our parts specialists are available to confirm fitment — no guesswork, no returns.
