OEM Carrier Flame Sensor (90°) for Model PY2PNB042060NB — Part #48GS400192

This is the genuine OEM Carrier flame sensor, part number 48GS400192, factory-specified for the Carrier PY2PNB042060NB gas furnace. The flame sensor — also called a flame rod — is a critical safety component that uses ionization/rectification to confirm a live burner flame during each heating cycle. When it fails or becomes coated with oxidation, the furnace control board receives no flame-confirmation signal and triggers a safety lockout, causing the furnace to light briefly and then shut down within 5–8 seconds. Replacing this sensor is one of the most common and cost-effective furnace repairs available.

  • Specs: 90° mounting angle | Rod-style flame sensor with bracket mount | OEM factory dimensions approx. 4.9" H × 1.75" W × 1.6" rod length | Direct factory replacement for part #48GS400192
  • OEM vs Generic: This is a genuine Carrier OEM part, manufactured to exact factory tolerances. Generic aftermarket sensors can vary in rod geometry and coating, leading to unreliable flame signal readings and repeat lockouts — always specify OEM for reliable, long-term performance.
  • Install difficulty: 1/5 — One of the simplest furnace repairs. Tools needed: 1/4" hex driver or nut driver, fine steel wool or emery cloth (to clean rod if needed). Turn off power and gas before servicing. Disconnect the single-wire connector, remove one mounting screw, swap sensor, reconnect wire. Total time: under 10 minutes.
  • Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse — order by 3 PM local time.

Compatibility: Designed for the Carrier PY2PNB042060NB gas furnace. If your furnace lights then shuts off after a few seconds on every call for heat, this sensor is the most likely culprit. Verify part number on your existing sensor or equipment data plate before ordering. Our fitment team is available to confirm compatibility before you buy — reach out before placing your order if you have any doubts.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PY2PNB042060NB — 48GS400192?

How do I replace the flame sensor on my Carrier PY2PNB042060NB — 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.
