OEM Carrier Flame Sensor 50HJ401431 for Model PY1REA048074AAWA

This is the genuine OEM Carrier flame sensor (part #50HJ401431) factory-specified for the Carrier PY1REA048074AAWA packaged gas heating unit. The flame sensor is a critical safety component: its stainless steel rod sits in the burner flame and uses microamp current rectification to confirm combustion is present. When the sensor fails — typically due to oxidation or carbon buildup on the probe — the control board cannot verify the flame, causing the unit to ignite briefly and then shut off after just 5–8 seconds, triggering a lockout. If your Carrier packaged unit lights and then immediately shuts off in a repetitive cycle, a failed flame sensor is the most common culprit.

  • Specs: OEM Part #50HJ401431 | Stainless steel sensing rod | Alumina-coated probe | Dimensions: approx. 2.9" W × 4" D × 1.75" H | Compatible with standard 24V AC control circuits
  • OEM vs Generic: This OEM part is manufactured to exact Carrier factory tolerances for microamp sensitivity and probe geometry. Generic sensors may have slightly off-spec rod lengths or coatings, leading to nuisance shutdowns or premature re-failure.
  • Install Difficulty: 2/5 — Shut off gas and power at the unit before beginning. Tools needed: 1/4" hex driver, needle-nose pliers, and a multimeter (to verify microamp draw on the new sensor). Always confirm the burner and heat exchanger area are clear before restoring power.
  • Warranty: 1-year OEM factory warranty. In-stock orders ship same business day from our warehouse when placed before cutoff.

Compatibility: Designed as a direct OEM replacement for the Carrier PY1REA048074AAWA packaged gas/electric unit. Verify part number against your unit's service data label before ordering.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PY1REA048074AAWA?
Yes. This is the factory-specified OEM flame sensor for the Carrier PY1REA048074AAWA. 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 PY1REA048074AAWA?
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.
