OEM Carrier 90° Flame Sensor (48GS400192) for Model PY2PNB024060NB

This OEM Carrier flame sensor is the factory-specified replacement for the Carrier PY2PNB024060NB gas furnace. The flame sensor — also called a flame rod — uses ionization/rectification technology to detect the presence of a burner flame during each heating cycle. When the control board calls for heat and the igniter lights the burners, the sensor passes a micro-amp DC signal through the flame back to ground. If that signal falls below threshold — whether from carbon buildup, a cracked rod, or a failed sensor — the board shuts off the gas valve within 5–8 seconds as a safety measure, causing the notorious "lights then immediately shuts off" symptom. Replacing this OEM part restores proper flame detection and eliminates nuisance lockouts.

  • Specs: 90° mounting angle | Includes mounting bracket | Rod length ~1.6 in. | Overall dimensions approx. 4.9 × 1.75 in. | OEM Part # 48GS400192
  • OEM vs Generic: This is a genuine Carrier OEM sensor built to factory micro-amp tolerances. Aftermarket sensors can drift out of spec quickly, causing repeat lockouts and unnecessary service calls.
  • Install Difficulty: 2/5 — Turn off power and gas before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, fine steel wool or emery cloth (to lightly clean rod if reusing), multimeter (to verify micro-amp reading post-install). Disconnect the single wire connector, remove the mounting screw, swap sensor, and reconnect.
  • Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY2PNB024060NB gas furnace. Always verify the OEM part number on your existing sensor or in your unit's wiring diagram before ordering.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PY2PNB024060NB?
Yes. This is the factory-specified OEM flame sensor for the Carrier PY2PNB024060NB. 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 PY2PNB024060NB?
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.
