OEM Carrier Flame Sensor (48GS400192) for Model PY3PEA048130NB

This is the factory OEM flame sensor for the Carrier PY3PEA048130NB gas furnace. The flame sensor (also called a flame rod) is a critical safety component mounted in the burner assembly. Using ionization/rectification technology, it detects the presence of a confirmed burner flame and relays a micro-amp signal back to the integrated furnace control board. If the board does not receive this signal within 5–8 seconds of ignition, it cuts gas flow and locks out the furnace — leaving you with no heat. A contaminated or failed sensor is one of the most common causes of nuisance lockouts in gas furnaces.

  • OEM Part Number: 48GS400192 | 90-degree mounting bracket | Factory-matched rod material and insulator for precise micro-amp output
  • OEM vs Generic: This is the genuine Carrier OEM part. Generic sensors may measure within spec when new, but use inferior rod alloys that carbon-foul faster, shortening service intervals and risking false lockouts.
  • Install Difficulty: 2/5 — Shut off gas and power before servicing. Tools needed: 1/4" nut driver, fine steel wool or emery cloth (for rod cleaning verification), multimeter (micro-amp mode). Disconnect the single wire connector, remove the mounting screw, swap the sensor, and reconnect. Always verify micro-amp reading on first fire-up.
  • Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our stocked warehouse.

How do I replace the flame sensor on my Carrier PY3PEA048130NB — 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.
