OEM Carrier 90° Flame Sensor (48GS400192) for Model PY3PPA048090NA

This is the genuine OEM Carrier flame sensor, part number 48GS400192, factory-specified for the Carrier PY3PPA048090NA gas furnace. The flame sensor — also called a flame rod — is a critical safety component that uses ionization/rectification technology to verify that a burner flame is present during each heating cycle. When the sensor detects no flame signal (or a degraded signal due to oxidation or carbon buildup), the furnace control board initiates a safety lockout, shutting the system down to prevent unburned gas accumulation. A failing flame sensor is one of the most common causes of a furnace that lights briefly and then shuts off after just 5 to 8 seconds.

  • Specs: 90° rod angle with factory mounting bracket | Flame rod length approx. 1.6 in. | Overall dimensions approx. 4.9 in. × 1.75 in. | Single-wire connection | OEM part #48GS400192
  • OEM vs Generic: This is a genuine Carrier OEM part, manufactured to exact factory tolerances for rod alloy composition and geometry. Generic flame sensors may exhibit inconsistent microamp output, causing nuisance lockouts or premature failure — especially in high-efficiency condensing furnaces with sensitive control boards.
  • Install Difficulty: 2/5 — A straightforward repair for most DIYers with basic tools. Turn off power and gas before beginning. Tools needed: 1/4 in. hex driver or flat-head screwdriver, needle-nose pliers, and a multimeter (to verify microamp output post-install). Always confirm the new sensor's rod is clean and free of contaminants before firing.
  • Warranty: Backed by a 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered as the direct factory replacement for the Carrier PY3PPA048090NA gas furnace. Always verify your existing part number on the sensor body or your unit's wiring diagram before ordering. Have a question about fitment? Our HVAC parts specialists confirm compatibility before you buy — no guesswork required.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PY3PPA048090NA — 48GS400192?

How do I replace the flame sensor on my Carrier PY3PPA048090NA — 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.
