OEM Carrier Flame Sensor 50HJ401431 for Model PY1RPA036074ABWA

This is the genuine OEM Carrier flame sensor (part #50HJ401431), factory-specified for the Carrier PY1RPA036074ABWA packaged gas heating unit. The flame sensor is a critical safety component: its stainless steel sensing rod sits in the burner flame and passes a small microamp current back to the control board to prove combustion is occurring. When the sensor fails — typically due to oxidation or carbon buildup on the rod — the control board cannot confirm ignition and will shut off the gas valve within 5 to 8 seconds of burner startup, triggering a safety lockout. The result is a system that appears to light and then immediately shuts down, often repeating 2–3 times before locking out entirely.

  • Specs: OEM Part # 50HJ401431 | Stainless steel sensing probe | Alumina-coated rod | Dimensions: 2.9" W × 4" D × 1.75" H | Weight: 0.09 lbs | Compatible with 24V AC control circuits
  • OEM vs Generic: This is a genuine Carrier OEM part, calibrated to the exact microamp threshold your control board expects. Aftermarket sensors often drift in sensitivity, causing nuisance lockouts or — worse — delayed shutoff. Always choose OEM for a safety-critical component like a flame sensor.
  • Install difficulty: 2/5 — Turn off gas and power at the breaker before beginning. Locate the flame sensor rod in the burner assembly; it is secured by a single 1/4" hex screw. Disconnect the wire lead, swap the sensor, and reconnect. Tools needed: 1/4" nut driver, needle-nose pliers, fine steel wool or emery cloth (to clean rod if reusing). Test through a full ignition cycle after reinstall.
  • Warranty: 1-year OEM factory warranty against defects. In-stock orders ship same business day from our warehouse when placed before cutoff.

Compatibility: Confirmed fit for Carrier model PY1RPA036074ABWA packaged gas heating unit. Verify your unit's data plate and existing part number before ordering. Our HVAC parts specialists are available to confirm fitment — contact us before you order if you have any questions.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PY1RPA036074ABWA?
Yes. This is the factory-specified OEM flame sensor for the Carrier PY1RPA036074ABWA. 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 PY1RPA036074ABWA?
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.
How fast does National HVAC Parts ship?
