OEM Carrier Flame Sensor 48GS400192 for Model PY3PEA048115NA

This is the genuine OEM factory-specified flame sensor (part number 48GS400192) for the Carrier PY3PEA048115NA gas furnace. The flame sensor — also called a flame rod — is a critical safety component that detects whether a burner flame is present after ignition. Using ionization/rectification technology, it passes a small electrical current through the flame; if no valid signal is returned to the control board within a few seconds, the board shuts off the gas valve and locks out, preventing unburned gas from accumulating. The most common symptom of a failed or fouled flame sensor is a furnace that lights, runs for 5–8 seconds, then shuts off — often repeating 2–3 times before going into lockout mode.

  • Specs: 90° angled mounting bracket | OEM rod length approx. 1.6" | Overall dimensions approx. 4.9" × 1.75" | Includes mounting hardware | Carrier OEM part number 48GS400192
  • OEM vs Generic: This is a genuine Carrier OEM part — not an aftermarket substitute. OEM sensors are factory-calibrated to the exact microamp threshold your control board expects. Generic sensors can read inconsistently, causing nuisance lockouts or masking real safety faults.
  • Install Difficulty: 2/5 — Turn off power and gas before starting. Tools needed: 1/4" or 5/16" nut driver, fine steel wool or emery cloth (to clean rod if re-using), multimeter (to verify microamp draw after install). Disconnect the single wire connector, remove the mounting screw, swap the sensor, and reconnect. Always test for proper flame signal after reinstall.
  • Warranty: Backed by a 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Direct OEM replacement for the Carrier PY3PEA048115NA gas furnace. Always verify the part number on your existing sensor or equipment data plate before ordering. Not sure it fits? Our HVAC parts specialists confirm fitment before you buy — reach out before placing your order.

How do I replace the flame sensor on my Carrier PY3PEA048115NA — 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.
