OEM Carrier Flame Sensor LH33WZ518 for Model PG9MXA036060AASA

This is the genuine OEM Carrier flame sensor (part #LH33WZ518), factory-specified for the Carrier PG9MXA036060AASA gas furnace. The flame sensor is a critical safety component — its flame rod generates a small microamp current in the presence of a burner flame, signaling the control board that ignition was successful. When the sensor fails due to carbon buildup or a cracked rod, the furnace will light briefly then shut off after 5–8 seconds, often triggering a lockout fault code. Replacing this part restores reliable heat and prevents unnecessary service calls.

  • Part Number: LH33WZ518 | OEM Carrier replacement | Genuine factory-matched flame rod assembly
  • OEM vs Generic: OEM sensors meet exact microamp output specs required by the Carrier IFC control board. Generic flame sensors can read low, causing nuisance shutdowns even with a healthy burner flame.
  • Install Difficulty: 2/5 — Turn off gas and power before beginning. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers. Lightly sand the rod with fine steel wool if reinstalling; replace entirely if cracked or heavily oxidized. No soldering required.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Fits Carrier model PG9MXA036060AASA and is also used across Bryant, Carrier, and Payne furnace series including 58MEC, 58MTA, 58MTB, 352AAV, 352MAV, and PG9MXA series units. Always verify your unit's data plate and existing part number before ordering. Our team is available to confirm fitment — contact us before you buy.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PG9MXA036060AASA?
Yes. This is the factory-specified OEM flame sensor for the Carrier PG9MXA036060AASA. 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 PG9MXA036060AASA?
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.
