OEM Carrier Flame Sensor (48GS400192) for Model PY2PNB048090AB

This is the genuine OEM Carrier flame sensor, part number 48GS400192, factory-specified for the Carrier PY2PNB048090AB gas furnace. The flame sensor — also called a flame rod — is a critical safety component that uses ionization/rectification to detect whether a burner flame is present after ignition. When the sensor becomes coated with oxidation or simply fails, the furnace control board interprets the missing signal as a failed ignition, triggering a safety lockout. The telltale symptom: the furnace lights normally but shuts itself off within 5–8 seconds, then repeats the lockout cycle.

  • Specs: 90° mounting angle | Rod length approx. 1.6 in. | Overall dimensions approx. 4.9 in. × 1.75 in. | Single-rod flame rectification design | OEM part number 48GS400192
  • OEM vs Generic: This is a genuine Carrier OEM part — not an aftermarket substitute. OEM sensors are manufactured to exact metallurgical and dimensional tolerances, ensuring reliable microamp signal output. Generic sensors frequently drift out of spec, causing nuisance lockouts or failing prematurely.
  • Install difficulty: 2/5 — Straightforward replacement requiring a 1/4 in. hex driver and a small flat-blade screwdriver. Always shut off gas and 120V power before servicing. Lightly sand the rod with fine steel wool if reinstalling an old sensor. Photo the wire lead routing before disconnecting.
  • Warranty: Backed by a 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse.

Compatibility: Designed and factory-matched for the Carrier PY2PNB048090AB gas furnace. Always verify part number 48GS400192 against your unit's data plate or wiring diagram before ordering. Our HVAC parts specialists are available to confirm fitment — contact us before you buy. In stock and ready to ship today.

How do I replace the flame sensor on my Carrier PY2PNB048090AB — 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.
