OEM Carrier Flame Sensor Replacement for Furnace Model LC348TM402018

This OEM Carrier flame sensor is the genuine replacement rod for furnace model LC348TM402018. The flame sensor confirms a flame is present after ignition and tells the control board to keep the gas valve open—when it corrodes or wears out, the furnace lights briefly then shuts off on a flame-failure lockout. Built to exact Carrier specifications, this sensor restores reliable flame detection and ends the short-cycling that leaves the LC348TM402018 blowing cold air. Installation is easy and takes about 15–20 minutes with one screwdriver: disconnect power, remove the burner-access panel, unscrew the old sensor, transfer the wire, and reinstall. No recalibration or special tools needed, and the new rod arrives clean and ready to fire. The OEM part guarantees the correct rod length, probe material, and mounting alignment for long, dependable service. In stock and ready to ship—orders placed before 3PM CST ship the same day. Bring back safe, steady heat with the exact flame sensor Carrier engineered for your furnace.

Frequently Asked Questions

Does this flame_sensor fit my Carrier Furnace Model LC348TM402018?
Yes. This is the factory-specified OEM flame_sensor for the Carrier Furnace Model LC348TM402018. 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 LC348TM402018?
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.
