OEM Carrier Flame Sensor 50HJ401431 for Model PY1RJA048074AAWB

This is the factory OEM replacement flame sensor (part number 50HJ401431) for the Carrier PY1RJA048074AAWB packaged unit. The flame sensor is a safety-critical rod that detects the presence of a burner flame by passing a small microamp current through the flame to ground. When the sensor's rod becomes coated with oxidation or carbon deposits, the control board can no longer confirm combustion, triggering a safety lockout. The most common symptom is a furnace or packaged unit that successfully ignites, burns for 5–8 seconds, then shuts down — cycling repeatedly without producing sustained heat.

  • Specs: OEM part number 50HJ401431 | Factory-matched microamp sensing threshold | Rod and bracket assembly | Direct plug-in harness connector
  • OEM vs Generic: OEM flame sensors are calibrated to the exact microamp detection range required by the Carrier control board. Generic sensors may read outside tolerance, causing nuisance lockouts or — more critically — delayed shutoff on flame loss.
  • Install Difficulty: 2/5 — Always shut off gas supply and 24V power at the disconnect before servicing. Tools needed: 1/4" hex driver or nut driver, multimeter (to verify microamp draw post-install). Take a photo of the wiring connector before removal. Clean the mounting bracket surface before installing the new sensor.
  • Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Engineered specifically for the Carrier PY1RJA048074AAWB packaged unit. Verify your OEM part number on the unit's wiring diagram or data label before ordering. Our fitment specialists are available to confirm compatibility before you buy — no guesswork required. Order today and get same-day shipping on in-stock parts.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PY1RJA048074AAWB — 50HJ401431?

How do I replace the flame sensor on my Carrier PY1RJA048074AAWB — 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.
