OEM Carrier Flame Sensor for Furnace Model LC350HE400810

This genuine OEM Carrier flame sensor is the safety component that proves your burners have ignited and keeps the gas valve open for a full heating cycle. A dirty or worn-out sensor is the number-one reason a furnace lights and then shuts off after a few seconds, repeatedly short-cycling and failing to heat your home. Matched precisely to Carrier model LC350HE400810, this sensor restores accurate flame rectification and steady furnace operation. The swap is a quick, beginner-friendly repair, usually under 15 minutes: disconnect power, remove the single screw, unplug the lead, and install the new sensor. Genuine OEM material delivers the correct microamp signal your control board reads, preventing the false faults that generic sensors trigger. Stop the cycling, protect against lockouts, and enjoy reliable warmth again. Orders placed before 3PM CST ship same-day, getting your heat back without delay. Trust authentic Carrier components for accuracy and long service life every season.

Frequently Asked Questions

How do I replace the flame_sensor on my Carrier Furnace Model LC350HE400810?

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.
