OEM Carrier Flame Sensor 48GS400192 for Model PY3PEA036090NB

This is the factory OEM replacement flame sensor for the Carrier PY3PEA036090NB packaged gas/electric unit. The flame sensor — also called a flame rod — is a safety-critical component that detects the presence of a burner flame during each ignition cycle. When it fails or becomes coated with oxidation, the control board cannot confirm ignition and will shut off the gas valve within 5–8 seconds of startup, triggering a safety lockout. The result: a furnace that briefly lights, then goes cold — often misdiagnosed as a gas valve or igniter failure.

  • Specs: Total length 4 5/8" | Distance to bend 3" | Distance to end 1 5/8" | 120V gas furnace application | Country of origin: USA
  • OEM vs Generic: This is the exact factory-specified OEM part. OEM flame sensors are calibrated to the precise microamp threshold your Carrier control board expects. Generic sensors may produce inconsistent current signals, causing nuisance lockouts or unreliable ignition.
  • Install difficulty: 2/5 — Turn off gas supply and disconnect power before servicing. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers. Locate the sensor on the burner assembly, disconnect the single-wire harness, remove one mounting screw, and reverse to install. Clean any oxidation from the rod with fine steel wool before installation if reusing the wiring harness.
  • Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse stock.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PY3PEA036090NB?
Yes. This is the factory-specified OEM flame sensor for the Carrier PY3PEA036090NB. 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 PY3PEA036090NB?
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.
