OEM Carrier Flame Sensor Replacement for Furnace Model LC350HE400814

This genuine OEM Carrier flame sensor confirms that your burners have lit, acting as a key safety check on every heat cycle. Seated in the burner flame, it passes a tiny microamp signal to the control board to prove ignition; once the rod oxidizes, fouls, or cracks, the board can no longer sense flame and locks the furnace out, causing the classic light-then-shutdown short-cycle. This exact-fit replacement is built for Carrier model LC350HE400814, matching the original rod length, bracket geometry, and terminal for a true drop-in fit. Installation is rated easy at roughly 15 minutes: shut off power and gas, disconnect the wire lead, remove the single mounting screw, and reverse to install. The correct OEM sensor preserves proper grounding and reliable flame proving, eliminating nuisance no-heat lockouts. Each sensor is new, inspected, and fit-guaranteed. Order before 3PM CST and it ships same-day so you can restore safe, steady heat without delay. Keep an extra on hand for seasonal furnace maintenance.

Frequently Asked Questions

Does this flame_sensor fit my Carrier Furnace Model LC350HE400814?
Yes. This is the factory-specified OEM flame_sensor for the Carrier Furnace Model LC350HE400814. 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 Furnace Model LC350HE400814?
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.
