OEM Carrier Flame Sensor 50HJ401431 for Model PY1REA072074ACWA

This is the genuine OEM flame sensor for the Carrier PY1REA072074ACWA packaged rooftop unit. The flame sensor — also called a flame rod — monitors the burner during every heating cycle by passing a small microamp current through the flame to the burner ground. If your unit lights briefly and then shuts down within 5 to 8 seconds, a failed or contaminated flame sensor is the most common cause. Carbon buildup on the stainless steel probe insulates it from the flame, causing the control board to cut gas flow as a safety lockout.

  • Specs: OEM Part No. 50HJ401431 | Stainless steel sensing probe | Alumina-coated, corrosion-resistant construction | Dimensions: 2.9 in W × 4 in D × 1.75 in H | Weight: 0.09 lbs | Compatible with 24V AC control circuits
  • OEM vs Generic: This factory-matched OEM sensor meets Carrier's exact microamp threshold specifications. Generic sensors can have off-spec probe geometry or coating, leading to nuisance lockouts or reduced safety margin — always use OEM on commercial packaged units.
  • Install Difficulty: 2/5 — Shut off gas and power before servicing. Tools needed: 1/4" nut driver, fine steel wool or emery cloth (for probe cleaning if reusing), multimeter set to microamps. Confirm microamp reading is within the control board's required range after installation.
  • Warranty: 1-year OEM manufacturer warranty. In-stock units ship same business day when ordered by 3 PM local time.

Compatibility: Engineered as the direct factory replacement for Carrier model PY1REA072074ACWA. Verify OEM part number 50HJ401431 against your unit's service data plate before ordering.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PY1REA072074ACWA?
Yes. This is the factory-specified OEM flame sensor for the Carrier PY1REA072074ACWA. 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 PY1REA072074ACWA?
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.
