OEM Carrier Flame Sensor 50HJ401431 for Model PY1RPA036074ABWB

This is the genuine OEM Carrier flame sensor (part #50HJ401431) factory-specified for the Carrier PY1RPA036074ABWB packaged gas heating unit. The flame sensor — also called a flame rod — is a critical safety component mounted in the burner assembly. It passes a small microamp current through the flame to confirm combustion is present. When the sensor fails or its probe becomes coated with oxidation, the control board cannot verify a flame, triggering a safety lockout. The most common symptom: the burner ignites normally, runs for 5–8 seconds, then shuts off and the system goes into lockout — repeatedly.

  • Specs: OEM Part #50HJ401431 | Stainless steel sensing probe | Alumina-coated rod | Compact form factor: 2.9" W × 4" D × 1.75" H | 24V AC control circuit compatible
  • OEM vs Generic: This is a genuine Carrier OEM part, manufactured to exact factory tolerances for microamp signal sensitivity. Generic flame sensors may trigger nuisance lockouts or fail prematurely due to probe coating inconsistencies.
  • Install Difficulty: 2/5 — Shut off gas and power before servicing. Tools needed: 1/4" hex driver, flat-head screwdriver, needle-nose pliers. Inspect wire harness connector for corrosion. Lightly sand probe rod with fine steel wool if reusing harness.
  • Warranty: 1-year OEM factory warranty. In-stock orders ship same business day from our warehouse.

Compatibility: Engineered for the Carrier PY1RPA036074ABWB packaged gas/electric unit. Always verify your unit's data plate and OEM part number before ordering. Our team is available to confirm fitment — reach out before you buy.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PY1RPA036074ABWB?
Yes. This is the factory-specified OEM flame sensor for the Carrier PY1RPA036074ABWB. 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 PY1RPA036074ABWB?
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.
