OEM Carrier Flame Sensor (48GS400192) for Model PY3PEA048130AB

This is the genuine OEM Carrier flame sensor (part #48GS400192) — the factory-specified replacement for the Carrier PY3PEA048130AB gas furnace. The flame sensor is a critical safety component mounted in the burner assembly. Using the principle of flame rectification, it detects the microamp current produced when the burner lights and signals the control board that combustion is confirmed. When the sensor fails — typically due to oxidation on the sensing rod — the furnace will light, run for 5 to 8 seconds, then shut down on lockout. This cycle repeats until the fault is resolved.

  • Part Specs: 90-degree sensing rod orientation | Includes mounting bracket | Factory-matched microamp sensitivity | OEM part number 48GS400192 | Manufacturer: Carrier
  • OEM vs Generic: This is a genuine Carrier OEM part, manufactured to exact factory tolerances. Generic sensors can have inconsistent microamp sensitivity thresholds, causing nuisance lockouts or — worse — delayed safety shut-off. Trust the factory part for reliable ignition cycle performance.
  • Install Difficulty: 2/5 — A straightforward repair for most DIYers. Power down and shut off gas before starting. Tools needed: 1/4" nut driver, needle-nose pliers, fine steel wool or emery cloth (to clean rod if desired). Disconnect the single wire harness, remove the mounting screw, swap the sensor, and restore power. Total time: approximately 15–20 minutes.
  • Warranty: 1-year OEM manufacturer warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY3PEA048130AB gas furnace. Always cross-reference your unit's data plate and existing part number before ordering to confirm fitment. Not sure?

How do I replace the flame sensor on my Carrier PY3PEA048130AB — 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.
