OEM Carrier Flame Sensor (48GS400192) for Model PY3PNA030040NB

This OEM Carrier flame sensor (part #48GS400192) is the factory-specified replacement for the Carrier PY3PNA030040NB gas furnace. The flame sensor is a critical safety component: after the igniter lights the burner, this rod uses ionization/rectification to confirm a live flame is present. If it cannot detect the flame — due to carbon buildup or a failed rod — the control board cuts gas within 5–8 seconds as a safety lockout, leaving your home without heat. Replacing a contaminated or failed sensor is one of the most common and cost-effective furnace repairs available.

  • Part Specs: OEM Part #48GS400192 | 90° mounting bracket | Flame rod construction | Approx. 4.9" L × 1.75" H | Factory-matched electrical characteristics for accurate flame signal
  • OEM vs Generic: This is a genuine Carrier OEM sensor built to exact factory tolerances. Generic sensors can have inconsistent rod coatings and off-spec signal output, causing nuisance lockouts or, worse, delayed shutoff — always choose OEM for a safety-critical part like this one.
  • Install Difficulty: 2/5 — A straightforward single-wire swap accessible from the burner compartment. Tools needed: 1/4" nut driver, fine steel wool or emery cloth (to clean rod if reusing), and a multimeter to verify microamp signal post-install. Always cut power to the furnace at the breaker before servicing.
  • Warranty: 1-year OEM factory warranty against manufacturing defects. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Designed for the Carrier PY3PNA030040NB gas furnace. Verify part number 48GS400192 against your unit's data plate or existing sensor before ordering. Not sure it fits? Our HVAC parts specialists confirm fitment before you buy — contact us today and get your heat back on fast.

How do I replace the flame sensor on my Carrier PY3PNA030040NB — 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.
