OEM Carrier Flame Sensor 48GS400192 for Model PY3PPA030040NA

This is the genuine OEM Carrier flame sensor (part #48GS400192) — the factory-specified replacement for the Carrier PY3PPA030040NA gas furnace. The flame sensor is a critical safety component: after the igniter fires the burner, the sensor's rod detects the presence of flame via electrical rectification/ionization and sends a confirming signal back to the control board. When it fails or becomes coated with oxidation, the board receives no flame signal and shuts off the gas valve within 5–8 seconds of ignition — resulting in repeated short-cycle lockouts and a no-heat call.

  • Specs: 90-degree flame sensor with mounting bracket | Approx. rod length 1.6" | Overall dimensions: 4.9" × 1.75" | OEM part number 48GS400192 | Genuine Carrier replacement
  • OEM vs Generic: This is the factory OEM sensor, matched to Carrier's exact rectification current thresholds. Aftermarket sensors with loose tolerances can produce intermittent nuisance lockouts or fail prematurely in high-cycle commercial applications.
  • Install difficulty: 1/5 — One of the easiest furnace repairs. Tools needed: 1/4" hex driver, needle-nose pliers. Always shut off gas and 120V power before servicing. Lightly abrade the sensor rod with fine steel wool if reusing to remove oxidation coating.
  • Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY3PPA030040NA packaged gas furnace. Verify OEM part number 48GS400192 on your unit's parts label or wiring diagram before ordering. Need fitment help? Our HVAC parts specialists confirm compatibility before you buy — order with confidence and get back to heat fast.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PY3PPA030040NA?
Yes. This is the factory-specified OEM flame sensor for the Carrier PY3PPA030040NA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the flame sensor on my Carrier PY3PPA030040NA?
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.
