OEM Carrier 90° Flame Sensor (48GS400192) for Model PY3GNA060090NB

This is the OEM factory-specified flame sensor for the Carrier PY3GNA060090NB 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 the presence of a live burner flame and sends a microamp signal to the control board confirming ignition. If the signal is absent or too weak (typically due to oxidation or carbon buildup on the rod), the control board will shut off the gas valve within 5–8 seconds of each ignition attempt, triggering a lockout fault. Replacing the sensor with the correct OEM part restores proper signal strength and eliminates nuisance lockouts.

  • Specs: 90° mounting angle | Includes mounting bracket | Factory-matched microamp output | OEM Part# 48GS400192 | Approx. rod length 1.6 in., overall dimensions 4.9 × 1.75 in.
  • OEM vs Generic: This OEM sensor is manufactured to Carrier's exact metallurgical and dimensional specs, ensuring consistent flame signal output and a long service life. Generic sensors may have inconsistent rod coatings that degrade faster, causing repeat no-heat calls.
  • Install Difficulty: 2/5 — Turn off gas and power at the breaker before beginning. Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter (to verify microamp signal after install). Note wire connector orientation before unplugging. Clean the burner port area while the old sensor is removed.
  • Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse.

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?

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.
