OEM Carrier Flame Sensor 48GS400192 for Model PY3PNA060090NB

This OEM flame sensor (part# 48GS400192) is the factory-specified replacement for the Carrier PY3PNA060090NB gas furnace. The flame sensor — also called a flame rod — is a safety device that confirms a burner flame is present during each ignition cycle. The control board sends a small electrical current through the rod; if a flame is detected, the microamp signal tells the board to keep the gas valve open. When the sensor becomes coated with oxidation or carbon buildup, the signal weakens and the board shuts the furnace down within 5–8 seconds, triggering a fault lockout. Replacing it with a genuine OEM part restores precise factory-specified microamp sensitivity and keeps your furnace running safely all season.

  • Specs: OEM Part# 48GS400192 | Flame rod / flame sensor | Factory-matched microamp response | Direct plug-in connector for Carrier PY3PNA060090NB
  • OEM vs Generic: OEM flame sensors are manufactured to exact Carrier tolerances for rod material, coating, and connector geometry. Generic sensors often exhibit inconsistent microamp output, leading to nuisance shutdowns or, worse, delayed safety shutoff — neither of which is acceptable in a gas appliance.
  • Install Difficulty: 2/5 — Shut off gas supply and 120V power before beginning. Tools needed: 1/4" hex nut driver, needle-nose pliers, and a multimeter capable of reading microamps (to verify signal after install). Always inspect the burner assembly for cracks or debris before reinstalling the panel.
  • Warranty: 1-year OEM factory warranty against defects. Ships same business day when ordered before 3 PM local time.

Compatibility: Designed specifically for the Carrier PY3PNA060090NB gas furnace. Verify your OEM part number on the unit's data plate or existing sensor body before ordering.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PY3PNA060090NB?
Yes. This is the factory-specified OEM flame sensor for the Carrier PY3PNA060090NB. 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 PY3PNA060090NB?
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.
