OEM Carrier Flame Sensor 50HJ401431 for Model PY1REA120180ABWB

This is the factory OEM flame sensor (part #50HJ401431) for the Carrier PY1REA120180ABWB packaged gas heating unit. The flame sensor—also called a flame rod—is a critical combustion safety component. It detects the presence of a confirmed burner flame by passing a small microamp current through the flame to ground. When the sensor becomes coated with oxidation or carbon deposits, the control board can no longer verify flame and will shut off the gas valve within 5–8 seconds of ignition as a safety lockout. Replacing this sensor is one of the most common and cost-effective repairs in gas heating systems.

  • Specs: OEM part #50HJ401431 | Stainless steel sensing rod with alumina ceramic insulator | Dimensions: approx. 2.9" W × 4" D × 1.75" H | Compatible with 24V AC control circuits | Weight: 0.09 lbs
  • OEM vs Generic: This is the genuine Carrier OEM sensor, factory-calibrated to the exact microamp threshold required by your PY1REA120180ABWB control board. Generic sensors may have rod length or bracket angle variances that cause nuisance lockouts or incomplete flame signal readings.
  • Install Difficulty: 2/5 — Turn off gas supply and 120V power before servicing. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers, and a multimeter (to verify microamp signal 2–8 µA DC). Disconnect the single wire connector, remove the one mounting screw, swap the sensor, and reconnect. Always verify flame signal with a meter after install.
  • Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse when ordered by 3 PM local time.

Compatibility: Designed as the direct OEM replacement for the Carrier PY1REA120180ABWB packaged gas/electric unit. Verify your existing part number on the sensor bracket or equipment data plate before ordering. Our fitment team is available to confirm compatibility before you purchase — no guesswork required.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PY1REA120180ABWB?
Yes. This is the factory-specified OEM flame sensor for the Carrier PY1REA120180ABWB. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the flame sensor on my Carrier PY1REA120180ABWB?
Difficulty: Easy (10–15 min)
Step 1: Turn off power/gas. Step 2: Open furnace panel. Step 3: Locate flame sensor rod near burners. Step 4: Remove single mounting screw. Step 5: Clean rod with 400-grit sandpaper until shiny (or replace). Step 6: Reinstall and tighten. Most common furnace repair — saves $150–$300 vs technician.
My furnace lights then shuts off after a few seconds. Why?
Furnace lights then shuts off after 3–10 seconds = dirty flame sensor in 90% of cases. The sensor can’t detect flame through oxidation buildup. Fix: clean with 400-grit sandpaper (free, 15 min). If cleaning doesn’t work, replace the sensor.
Is this flame sensor compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier flame sensor?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
