OEM Carrier Flame Sensor (48GS400192) for Model PY3PPA048090NB

This is the genuine OEM Carrier flame sensor, part number 48GS400192, factory-specified for the Carrier PY3PPA048090NB gas furnace. The flame sensor is a safety-critical component that uses ionization/rectification to detect the presence of a burner flame during each heating cycle. When functioning correctly, it allows the gas valve to stay open and the furnace to run. When the sensor rod becomes coated with oxidation or fails entirely, the furnace will light briefly — then shut down within 5 to 8 seconds, triggering a lockout fault. This is one of the most common causes of a no-heat call in gas furnaces.

  • Specs: 90-degree mounting angle | Compact rod-style flame sensor with mounting bracket | Approx. 4.9" H × 1.75" W × 1.6" rod length | OEM part number 48GS400192
  • OEM vs Generic: This is a genuine Carrier OEM part — not an aftermarket substitute. OEM sensors are manufactured to exact factory tolerances for signal sensitivity and rod metallurgy, ensuring reliable flame detection and preventing nuisance lockouts caused by undersized or poorly matched aftermarket rods.
  • Install Difficulty: 2/5 — A straightforward repair for most homeowners. Tools needed: 1/4" nut driver or 5/16" socket, fine steel wool or emery cloth (to clean rod if reinstalling old sensor), and a multimeter (optional, for diagnosis). Always shut off power and gas before servicing. The sensor typically mounts to the burner manifold with a single screw and connects to one wire lead.
  • Warranty: 1-year OEM manufacturer warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY3PPA048090NB gas furnace. Verify your unit's part number against the data plate inside the furnace cabinet before ordering.

How do I replace the flame sensor on my Carrier PY3PPA048090NB — 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.
