OEM Carrier Flame Sensor FS-LC350 for Model LC350TM400570

This OEM Carrier flame sensor is a direct-fit replacement designed for the LC350TM400570 furnace, delivering accurate flame rectification that confirms burner ignition and keeps your heating system safe. Over time, the sensor can weaken or accumulate a carbon layer, losing its ability to detect flame and triggering the control board to shut down the burners—resulting in short-cycling or no-heat conditions. This genuine Carrier sensor restores dependable flame sensing and smooth furnace operation. Built to factory specifications, it provides the correct microamp signal and exact mounting alignment with the LC350TM400570 burner assembly. Installation is easy, typically taking 15-20 minutes with basic tools, ideal for a confident DIYer or a quick technician swap. Always shut off power and gas before servicing. An OEM sensor offers greater durability and reliable performance compared to generic alternatives. Orders placed before 3PM CST ship same-day, getting your furnace running again fast.

Frequently Asked Questions

Does this flame_sensor fit my Carrier Model LC350TM400570?
Yes. This is the factory-specified OEM flame_sensor for the Carrier Model LC350TM400570. 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 Model LC350TM400570?
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.
