OEM Carrier Flame Sensor 50HJ401431 for Model PY1REA036074ABWA

This is the genuine OEM Carrier flame sensor (part #50HJ401431), the factory-specified replacement for the Carrier PY1REA036074ABWA packaged gas heating unit. The flame sensor is a critical safety component — it uses a small electrical current passed through a stainless steel sensing rod to confirm the presence of a burner flame after ignition. When the sensor rod becomes coated with oxidation or carbon buildup, its microamp signal drops below the control board's threshold, triggering a safety lockout. The telltale symptom is a burner that lights normally but shuts off within 5–8 seconds, repeating 3 times before locking out entirely.

  • Specs: OEM part #50HJ401431 | Stainless steel sensing probe | Alumina-coated rod for corrosion resistance | Dimensions: approx. 2.9" W × 4" D × 1.75" H | Compatible with standard 24V AC control circuits
  • OEM vs Generic: This is a genuine Carrier OEM sensor, calibrated to exact factory microamp specifications. Generic aftermarket sensors can have wider tolerance bands, causing nuisance lockouts or — worse — delayed shutoff responses. OEM is always the recommended choice for safety-critical combustion components.
  • Install Difficulty: 2/5 — Straightforward single-screw mount replacement. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers. Always shut off gas supply and 24V power before servicing. Lightly sand the sensing rod with fine steel wool if reinstalling an old sensor; replace entirely if microamp reading is below 2µA.
  • Warranty & Shipping: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed as a direct OEM replacement for the Carrier PY1REA036074ABWA packaged gas/electric unit. Verify part number on your unit's existing sensor or data plate before ordering. Our team is available to confirm fitment — contact us before you order if you have any questions.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PY1REA036074ABWA?
Yes. This is the factory-specified OEM flame sensor for the Carrier PY1REA036074ABWA. 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 PY1REA036074ABWA?
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.
