OEM Carrier Flame Sensor FS-LC350 for Model LC350TM400569

This OEM Carrier flame sensor is a direct-fit replacement engineered for the LC350TM400569 furnace, providing accurate flame rectification that confirms burner ignition and keeps your heating system operating safely. As the sensor ages or builds up a carbon coating, it can no longer detect the flame, causing the control board to shut off the burners and producing short-cycling or no-heat issues. This genuine Carrier sensor restores reliable flame detection and steady furnace performance. Built to factory specifications, it ensures the correct microamp signal and precise mounting fit on the LC350TM400569 burner assembly. Installation is easy and usually takes 15-20 minutes with basic hand tools, making it a manageable repair for handy homeowners or a fast swap for HVAC pros. Always turn off power and gas before servicing. An OEM sensor provides better durability and dependable accuracy than generic options. Orders placed before 3PM CST ship same-day, getting your heat back fast. Rely on NationalHVACParts.com for genuine Carrier parts and quick, reliable delivery.

Frequently Asked Questions

Does this flame_sensor fit my Carrier Model LC350TM400569?
Yes. This is the factory-specified OEM flame_sensor for the Carrier Model LC350TM400569. 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 LC350TM400569?
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.
