OEM Carrier Flame Sensor 50HJ401431 for Model PY1RJA048115AAWA

This is the genuine OEM flame sensor (part #50HJ401431) factory-specified for the Carrier PY1RJA048115AAWA packaged gas heating unit. The flame sensor is a critical safety component: its stainless steel rod sits directly in the burner flame and passes a small microamp current to the control board to confirm combustion. When the sensor fails — typically due to oxidation or carbon buildup on the probe — the control board cannot verify a flame is present and shuts off the gas valve within 5–8 seconds as a safety lockout. The result is a system that appears to light, then immediately shuts down and locks out, leaving occupants without heat.

  • Part Specs: OEM Part # 50HJ401431 | Stainless steel sensing rod | Alumina-coated probe | Dimensions: approx. 2.9" W × 4" D × 1.75" H | Weight: 0.09 lbs | Compatible with 24V AC control circuits
  • OEM vs. Generic: This factory-matched OEM sensor maintains precise microamp output tolerance required by the Carrier control board. Generic sensors may fall outside the accepted µA range, causing nuisance lockouts or false flame readings — always use OEM in commercial packaged units.
  • Install Difficulty: 2/5 — Shut off gas and power before servicing. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers, multimeter (set to microamps to verify 2–6 µA reading after installation). Always confirm gas valve closes fully before restarting the unit.
  • Warranty & Shipping: 1-year OEM factory warranty. In stock and ships same business day when ordered before cutoff. Fast, reliable delivery to your door or jobsite.

Compatibility: Engineered as a direct OEM replacement for Carrier model PY1RJA048115AAWA. Verify your unit's data plate and existing part number before ordering. Our parts specialists are available to confirm fitment — don't hesitate to reach out before you buy.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PY1RJA048115AAWA?
Yes. This is the factory-specified OEM flame sensor for the Carrier PY1RJA048115AAWA. 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 PY1RJA048115AAWA?
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.
