OEM Carrier Flame Sensor for Carrier Furnace Model LC350HE400800

This OEM Carrier flame sensor is the genuine flame-rectification rod that proves the burner is lit during every heating cycle on your Carrier furnace. It sends a microamp signal to the control board confirming flame is present; once the rod oxidizes or coats with carbon, the board can no longer detect flame and shuts the gas valve, causing the furnace to ignite then drop out after a few seconds. Installing this factory sensor restores a clean, strong signal and ends nuisance no-heat lockouts. It is a direct-fit replacement for Carrier model LC350HE400800, matching the original rod length, bend, and mounting bracket for correct flame positioning. This is one of the easier furnace repairs: shut off power, remove a single screw, unplug the spade connector, and seat the new sensor, typically 15 to 20 minutes with a nut driver. Avoid touching the rod with bare fingers. Order before 3PM CST and your flame sensor ships the same business day from our in-stock inventory, getting your system back to reliable heating.

Frequently Asked Questions

Yes. This is the factory-specified OEM flame_sensor for the Carrier Carrier Furnace Model LC350HE400800. 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 Carrier Furnace Model LC350HE400800?
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.
