OEM Carrier Flame Sensor 48GS400192 for Model PY1PEB036090AAAA

This is the genuine OEM flame sensor (part number 48GS400192) factory-specified for the Carrier PY1PEB036090AAAA packaged gas/electric unit. The flame sensor — also called a flame rod — is a safety device mounted in the burner assembly that detects whether a flame is actually present after the igniter fires. It does this by passing a small electrical current through the flame; if the signal is not detected within a few seconds, the control board shuts off the gas valve to prevent unburned gas buildup. When the sensor fails or becomes coated with oxidation, the most tell-tale symptom is a system that ignites and then shuts off after just 5 to 8 seconds, often cycling through 3 lockout attempts before going into hard lockout and triggering a fault code.

  • Specs: OEM part number 48GS400192 | Factory-matched rod diameter and insertion length | Compatible with Carrier-branded packaged unit burner assemblies | Direct plug-and-play replacement — no modifications required
  • OEM vs Generic: The OEM sensor ensures the exact rod alloy composition, insulator ceramic grade, and terminal connector type specified by Carrier engineering. Generic flame sensors may use inferior rod coatings that oxidize faster, causing repeat nuisance shutdowns and premature control board wear.
  • Install difficulty: 2/5 — Turn off gas and power at the disconnect before beginning. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers, and a soft wire brush to clean the mounting bracket. Do not handle the ceramic insulator with bare hands — skin oils accelerate ceramic degradation. Always clear any active lockout fault codes after replacement.
  • Warranty: 1-year OEM manufacturer warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Engineered as a direct OEM replacement for the Carrier PY1PEB036090AAAA 3-ton, 90,000 BTU packaged gas/electric unit. Always verify the part number on your existing sensor or the unit's wiring diagram before ordering. Our fitment team is available to confirm compatibility — reach out before you buy.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PY1PEB036090AAAA?
Yes. This is the factory-specified OEM flame sensor for the Carrier PY1PEB036090AAAA. 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 PY1PEB036090AAAA?
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.
