OEM Carrier Flame Sensor 48GS400192 for Model PY3GNA048090AB

This OEM flame sensor (part number 48GS400192) is the factory-specified replacement for the Carrier PY3GNA048090AB packaged gas/electric unit. The flame sensor is a critical safety component — its flame rod detects the presence of a burner flame by passing a small electrical current through it. If the control board does not receive confirmation of flame within a few seconds of gas valve opening, it will shut down the burner as a safety precaution. A failed or contaminated flame sensor is one of the most common causes of a furnace or packaged unit that lights briefly and then shuts off after just 5–8 seconds, often triggering a lockout fault code.

  • Specs: OEM part number 48GS400192 | Factory flame rod assembly | Direct drop-in fit for Carrier PY3GNA048090AB | Engineered to meet original factory electrical resistance specifications
  • OEM vs Generic: OEM flame sensors are manufactured to exact factory tolerances for rod geometry and ceramic insulation quality. Generic sensors may exhibit higher resistance readings, causing nuisance shutdowns and repeat service calls even after replacement.
  • Install Difficulty: 2/5 — Shut off gas and electrical power before servicing. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers, and a multimeter (to verify microamp signal after install). Before removing, photograph the wire connector orientation. Clean the burner area of any debris before reinstalling.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock and ships same business day from our warehouse.

How do I replace the flame sensor on my Carrier PY3GNA048090AB — 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.
