OEM Carrier Flame Sensor (50HJ401431) for Model PY1REA150224ADWA

This is the factory OEM replacement flame sensor for the Carrier PY1REA150224ADWA furnace. The flame sensor — also called a flame rod — is a critical safety component that detects the presence of a burner flame and sends a small microamp signal to the control board to confirm ignition. When the sensor becomes coated with oxidation or fails entirely, the control board cannot verify a flame is present and will shut off the gas valve within 5 to 8 seconds of ignition as a safety precaution, causing a lockout condition. This is one of the most common causes of a furnace that "lights then goes out" repeatedly.

  • OEM Part Number: 50HJ401431 | Factory-direct replacement | Exact fit for Carrier PY1REA150224ADWA
  • OEM vs Generic: This OEM sensor is manufactured to Carrier's exact microamp output and rod geometry specifications. Generic sensors may produce inconsistent microamp readings, triggering nuisance lockouts or failing to satisfy the control board's flame-prove threshold.
  • Install Difficulty: 2/5 — Turn off power and gas before servicing. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers. Disconnect the single wire connector, remove the mounting screw, swap the sensor, and restore power. Always verify microamp signal (1.5–4 µA typical) with a multimeter after install.
  • Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for the Carrier PY1REA150224ADWA furnace. Verify your existing part number on the sensor or equipment data plate before ordering.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier Model PY1REA150224ADWA | 50HJ401431?

How do I replace the flame sensor on my Carrier Model PY1REA150224ADWA | 50HJ401431?
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.
