OEM Carrier Flame Sensor (48GS400192) for Model PY3PNA048115NA

This is the genuine OEM Carrier flame sensor, part number 48GS400192, factory-specified for the Carrier PY3PNA048115NA gas furnace. The flame sensor — also called a flame rod — is a critical safety component mounted in the burner assembly. When the burner ignites, the sensor detects the presence of flame via electrical rectification or ionization and sends a signal to the control board confirming ignition. If the sensor is coated with oxidation or carbon buildup, or has failed entirely, the control board cannot confirm flame and will shut off the gas valve — typically 5 to 8 seconds after each ignition attempt. The result is a furnace that repeatedly lights and immediately shuts off, locking out after 3 attempts.

  • Specs: 90° angle flame rod with mounting bracket | OEM part number 48GS400192 | Dimensions approx. 4.9" L × 1.75" H | Factory-matched rectification signal output
  • OEM vs Generic: This is the genuine Carrier OEM sensor, not an aftermarket substitute. OEM sensors provide the exact rod angle, bracket geometry, and signal characteristics specified by the factory — ensuring reliable flame recognition and preventing nuisance lockouts.
  • Install Difficulty: 2/5 — Turn off power and gas before servicing. Disconnect the single wire connector, remove the mounting screw(s), and swap the sensor. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers. Lightly clean the rod with fine steel wool if reusing the mount. Total job: under 15 minutes.
  • Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY3PNA048115NA gas furnace. Always confirm the OEM part number on your existing sensor or equipment data plate before ordering.

How do I replace the flame sensor on my Carrier PY3PNA048115NA — 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.
