OEM Carrier Flame Sensor (48GS400192) for Model PY3PNA030040AB

This is the genuine OEM Carrier flame sensor (part #48GS400192) — the factory-specified replacement for the Carrier PY3PNA030040AB gas furnace. The flame sensor is a critical safety component: once the burner ignites, the sensor uses ionization/rectification technology to detect the presence of a live flame and send a confirmation signal back to the control board. If the sensor is coated with oxidation or has failed entirely, the control board will cut gas flow within 5–8 seconds of ignition, causing the furnace to lock out and cycle repeatedly without producing heat.

  • Specs: 90° mounting angle | Includes integrated mounting bracket | OEM part #48GS400192 | Dimensions approx. 4.9" L × 1.75" H × 1.6" W | Factory-matched signal tolerance
  • OEM vs Generic: This is a genuine Carrier OEM sensor built to exact factory specifications. Generic aftermarket sensors can produce inconsistent microamp readings, causing nuisance lockouts or — worse — false flame confirmation. OEM is the only safe choice for a gas combustion safety device.
  • Install difficulty: 2/5 — Turn off gas and power before servicing. Locate the sensor rod in the burner assembly, disconnect the single wire connector, remove the mounting screw, and reverse to install. Tools needed: 1/4" or 5/16" nut driver, soft cloth or fine steel wool to clean rod tip if reusing. Total time: under 15 minutes.
  • Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse.

Compatibility: Engineered for the Carrier PY3PNA030040AB gas furnace. Always confirm the OEM part number on your existing sensor or equipment data plate before ordering. Our fitment team is available to verify compatibility before you buy — same-day shipping on all in-stock orders.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PY3PNA030040AB?
Yes. This is the factory-specified OEM flame sensor for the Carrier PY3PNA030040AB. 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 PY3PNA030040AB?
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.
