OEM Carrier Flame Sensor 48GS400192 for Model PY3PEA042090NA

This is the OEM factory-matched flame sensor for the Carrier PY3PEA042090NA packaged unit. The flame sensor (also called a flame rod) is a critical safety component that detects the presence of a burner flame during the ignition sequence. When the control board energizes the gas valve and igniter, the flame sensor generates a small microamp current through the flame to confirm combustion. If the sensor is coated with oxidation or has failed entirely, the board cannot verify ignition and will shut down gas flow — resulting in the furnace lighting briefly, then cutting out after just 5–8 seconds, typically triggering a fault lockout code.

  • Specs: OEM part number 48GS400192 | Factory-specified flame rod assembly | Correct rod length, bend angle, and ceramic insulator for model PY3PEA042090NA | Produces proper microamp signal within board-specified threshold
  • OEM vs Generic: OEM flame sensors use precision-matched rod geometry and high-purity ceramic insulators. Generic alternatives may produce marginal microamp readings that cause nuisance lockouts or intermittent heating faults — especially in colder weather when the control board's threshold sensitivity is taxed.
  • Install difficulty: 2/5 — Straightforward single-screw replacement. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers. Always shut off power and gas before servicing. Clean burner area of debris and confirm microamp reading (1.5–4 µA typical) with a multimeter after installation.
  • Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Designed and factory-specified for the Carrier PY3PEA042090NA packaged gas/electric unit. Always cross-reference the OEM part number 48GS400192 on your unit's wiring diagram or parts list before ordering. Not sure it fits?

How do I replace the flame sensor on my Carrier PY3PEA042090NA — 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.
