OEM Carrier Flame Sensor for Model LC350TM400568 - Furnace Rod

This genuine OEM Carrier flame sensor is designed for the LC350TM400568 furnace and confirms the presence of a burner flame during each heating cycle. Using flame rectification, it signals the control board that ignition succeeded, allowing the gas valve to stay open safely. Over time, carbon and oxidation build up on the rod, causing weak signals, short cycling, and frustrating no-heat lockouts. Replacing the sensor restores a strong, reliable flame signal and eliminates intermittent shutdowns. This direct-fit replacement matches the original mounting bracket, rod length, and electrical terminal for the LC350TM400568, requiring no modification. Installation is easy and a quick repair—turn off power and gas, remove the single mounting screw, disconnect the wire, and install the new sensor in minutes. A genuine Carrier sensor ensures accurate flame detection and safe operation versus generic alternatives. Keep your furnace running dependably through the heating season with a factory-spec part. Orders placed before 3PM CST ship the same day for fast turnaround on your repair.

Frequently Asked Questions

Does this flame_sensor fit my Carrier Model LC350TM400568 - Furnace Rod?
Yes. This is the factory-specified OEM flame_sensor for the Carrier Model LC350TM400568 - Furnace Rod. 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 LC350TM400568 - Furnace Rod?
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.
