OEM Carrier Flame Sensor Replacement for Model LC350TM400558

This genuine OEM Carrier flame sensor verifies that the burner flame is present and tells the control board to maintain gas flow for continuous heating. A dirty, oxidized, or failed sensor causes the furnace to light and then drop out after a few seconds, producing repeated short cycles and inconsistent heat. This factory-spec replacement is precision-matched to Carrier model LC350TM400558, ensuring proper flame rectification and a strong microamp signal for safe, steady operation. Manufactured to OEM tolerances, it restores reliable flame detection and prevents nuisance lockouts. Installation is among the simplest furnace repairs—generally 15-20 minutes with one mounting screw and a single wire connector, suitable for a careful DIYer, though a licensed professional is recommended if you have any doubts. Get dependable, uninterrupted heat with a component built to factory standards rather than a generic approximation. Every order placed before 3PM CST ships same-day, so your Carrier furnace is back in service without delay. Choose authentic OEM quality for safe and consistent performance all season long.

Frequently Asked Questions

Does this flame_sensor fit my Carrier Model LC350TM400558?
Yes. This is the factory-specified OEM flame_sensor for the Carrier Model LC350TM400558. 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 LC350TM400558?
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.
