OEM Carrier Flame Sensor (48GS400192) for Model PY2PNB036090AA

This is the factory OEM replacement flame sensor for the Carrier PY2PNB036090AA gas furnace. The flame sensor — also called a flame rod — is a critical safety component that uses ionization/rectification technology to verify a live burner flame during each heating cycle. When it detects the flame's electrical signal, it tells the control board to keep the gas valve open. A failed or carbon-coated sensor can no longer pass sufficient microamp current, causing the furnace to light briefly and then shut down within 5–8 seconds, triggering a lockout fault code. Replacing this part restores normal heating operation immediately.

  • OEM Part Number: 48GS400192 | 90-degree mounting angle | Includes mounting bracket | Factory-matched for Carrier PY2PNB036090AA
  • OEM vs Generic: This is a genuine Carrier OEM part manufactured to exact factory tolerances. Aftermarket flame sensors often use lower-grade rod alloys that coat with carbon faster, reducing service life and causing repeat nuisance shutdowns.
  • Install Difficulty: 2/5 — Turn off gas and power before servicing. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers, and optionally a multimeter to confirm microamp draw after installation. The sensor mounts with a single screw near the burner assembly — a straightforward swap for most DIYers.
  • Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier PY2PNB036090AA gas furnace. Always verify the OEM part number on your existing sensor or equipment data plate before ordering. If you have any fitment questions, our HVAC parts specialists are available to confirm compatibility before you buy — no guesswork required.

How do I replace the flame sensor on my Carrier PY2PNB036090AA — 48GS400192?
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.
