OEM Carrier Flame Sensor (48GS400192) for Model PY2PNB024040AC

This is the genuine OEM Carrier flame sensor, part number 48GS400192, factory-specified for the Carrier PY2PNB024040AC gas furnace. The flame sensor is a critical safety component — it uses ionization/rectification technology to detect the presence of a burner flame and sends a microamp signal to the control board confirming ignition. When the sensor fails or becomes coated with oxidation, the furnace will light briefly and then shut off after 5–8 seconds, often triggering a fault lockout code. Replacing the flame sensor is one of the most common and cost-effective furnace repairs available.

  • Specs: 90° angle mounting configuration | Includes factory mounting bracket | OEM part number 48GS400192 | Approximate rod length 1.6" | Overall dimensions approx. 4.9" × 1.75"
  • OEM vs Generic: This is a genuine Carrier OEM sensor, manufactured to exact factory tolerances for microamp output and rod geometry. Generic sensors may produce inconsistent microamp readings, causing nuisance lockouts or premature control board wear.
  • Install Difficulty: 2/5 — Power down and lock out the furnace before beginning. Tools needed: 1/4" or 5/16" nut driver, flathead screwdriver, fine steel wool or light sandpaper to clean burner bracket if needed. Disconnect the single wire connector, remove the mounting screw, swap the sensor, and reconnect. Job typically takes under 15 minutes.
  • Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed for the Carrier PY2PNB024040AC gas furnace. Always verify the part number on your existing sensor or equipment data plate before ordering. Our fitment team is available to confirm compatibility before you buy — no guesswork required. In stock and ready to ship today.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PY2PNB024040AC?
Yes. This is the factory-specified OEM flame sensor for the Carrier PY2PNB024040AC. 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 PY2PNB024040AC?
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.
