OEM Carrier Flame Sensor (48GS400192) for Model PY2PNB024040NB

This is the genuine OEM replacement flame sensor for the Carrier PY2PNB024040NB gas furnace. The flame sensor — also called a flame rod — is a critical safety component mounted in the burner assembly. Using ionization/rectification technology, it detects a small microamp DC current produced when the burner flame contacts the rod. If the signal falls below threshold, the control board cuts gas flow within 5–8 seconds to prevent unburned gas accumulation. A failed or contaminated flame sensor is one of the most common causes of a furnace that lights, runs briefly, and then locks out — often generating a fault code on the control board.

  • Part Number & Specs: OEM Part #48GS400192 | 90-degree rod orientation with integrated mounting bracket | Approximate dimensions: 4.9" H × 1.75" W × 1.6" rod length | Factory-matched signal tolerance for the PY2PNB024040NB control board
  • OEM vs. Generic: OEM sensors are manufactured to exact rod alloy and geometry specifications. Off-brand sensors can produce weak or inconsistent microamp readings, causing nuisance lockouts — especially in colder weather when the control board demands a faster, cleaner flame signal.
  • Install Difficulty: 1/5 — One of the easiest furnace repairs. Tools needed: 1/4" hex driver or nut driver, fine steel wool or light sandpaper (to clean rod if reusing), and a multimeter to verify microamp draw post-install. Turn off gas and 24V power before disconnecting the sensor lead.
  • Warranty & Shipping: Backed by a 1-year OEM manufacturer warranty against defects. In stock and ships same business day from our warehouse.

Compatibility: Designed as the direct OEM replacement for Carrier model PY2PNB024040NB. Always verify your existing part number on the sensor body or equipment data plate before ordering.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PY2PNB024040NB?
Yes. This is the factory-specified OEM flame sensor for the Carrier PY2PNB024040NB. 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 PY2PNB024040NB?
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.
How fast does National HVAC Parts ship?
