OEM Carrier Flame Sensor (48GS400192) for Model PY2PNB060090AA Gas Furnace

This is the genuine OEM Carrier flame sensor, part number 48GS400192, factory-specified for the Carrier PY2PNB060090AA gas furnace. The flame sensor is a safety-critical component that uses ionization/rectification technology to confirm the presence of a burner flame during each heating cycle. When it detects a valid flame signal, it keeps the gas valve open and allows normal heating operation. A failed or carbon-fouled sensor cannot read the ionization current correctly — causing the control board to cut gas flow as a safety precaution, typically 5–8 seconds after ignition. The result: the furnace lights briefly, then shuts down and goes into lockout, repeating the cycle with no heat delivered.

  • Part Specs: 90-degree mounting angle | Compact rod-style flame sensor | Factory-matched ionization current range | Approx. 4.9″ L × 1.75″ H × 1.6″ W
  • OEM vs. Generic: This is a genuine Carrier OEM part — not an aftermarket substitute. OEM sensors are manufactured to exact ionization sensitivity tolerances, ensuring reliable flame detection and minimizing nuisance lockouts common with off-spec generic sensors.
  • Install Difficulty: 2/5 — Straightforward replacement. Turn off power and gas before servicing. Tools needed: ¼″ hex driver, needle-nose pliers, and a soft cloth or fine steel wool to clean the mounting bracket. Always inspect the wire harness connector for corrosion before installing the new sensor.
  • Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY2PNB060090AA gas furnace. Verify your unit's model and data plate before ordering to ensure correct fitment. Our team is available to confirm compatibility — order with confidence and enjoy fast, same-day shipping on in-stock parts.

How do I replace the flame sensor on my Carrier PY2PNB060090AA — 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.
