OEM Carrier Flame Sensor LH33WZ009A for Model LC3:50HE400802

This is the factory OEM replacement flame sensor (part number LH33WZ009A) for the Carrier LC3:50HE400802 packaged unit. The flame sensor is a critical safety component — a metal rod positioned in the burner flame that passes a small electrical current through the flame to prove ignition to the control board. When the sensor becomes coated with oxidation or carbon buildup, it can no longer accurately detect the flame, causing the furnace to light briefly and then shut down on lockout after 5–8 seconds. Left unaddressed, repeated lockout cycles can stress the control board and igniter.

  • Specs: OEM part number LH33WZ009A | Factory flame rod geometry and ceramic insulator | Matched to Carrier LC3:50HE400802 control board signal thresholds
  • OEM vs Generic: The OEM sensor provides the exact rod length, bend angle, and ceramic insulator rating specified for this unit. Generic sensors may have inconsistent rod positioning relative to the burner flame, leading to nuisance lockouts or premature failure.
  • Install Difficulty: 2/5 — Shut off gas supply and power before beginning. Tools needed: 1/4" hex driver or nut driver, fine steel wool or emery cloth (to clean rod if reusing), and a multimeter for post-install verification. Single mounting screw; disconnect one wire connector. Always confirm gas is off and system is de-energized prior to any work.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed specifically for the Carrier LC3:50HE400802 packaged unit. Verify OEM part number LH33WZ009A against your unit's data plate and existing sensor before ordering. Not sure if this is the right part? Our HVAC parts team confirms fitment before you buy — no guesswork required. In stock and ships today.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier LC3:50HE400802?
Yes. This is the factory-specified OEM flame sensor for the Carrier LC3:50HE400802. 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 LC3:50HE400802?
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.
How fast does National HVAC Parts ship?
