OEM Carrier Igniter LC348TM402773 for Model LC348TM402773

This OEM Carrier hot surface igniter is the genuine ignition component for Carrier model LC348TM402773 gas furnaces and packaged units. It generates the high-temperature surface needed to ignite the burner gas on each heating cycle, restoring reliable startups and eliminating no-heat calls caused by a cracked, worn, or carbon-fouled igniter. Built to exact factory specifications, it delivers the precise resistance and silicon-nitride durability your Carrier system was engineered for, so you avoid the short lifespan of universal aftermarket substitutes. Installation is a moderate, do-it-yourself-friendly repair for handy homeowners and a quick swap for any HVAC technician: shut off power and gas, unplug the connector, remove the mounting screw, and reverse to install—handle only by the ceramic base. Pairs perfectly with a fresh flame sensor for a complete ignition tune-up. Backed by genuine Carrier quality for dependable winter heating. In stock and ready to ship same-day on all orders placed before 3PM CST, so you get your furnace running fast.

Frequently Asked Questions

Does this Igniter fit my Carrier Model LC348TM402773?
Yes. This is the factory-specified OEM igniter for the Carrier Model LC348TM402773. 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 igniter on my Carrier Model LC348TM402773?
Difficulty: Medium (20–30 min)
Step 1: Turn off power and gas. Step 2: Open furnace panel. Step 3: Locate igniter near burners. Step 4: Disconnect two-wire plug. Step 5: Remove mounting screw. Step 6: Install new igniter — do NOT touch element with fingers. Step 7: Reconnect, close panel, restore power/gas.
My furnace won’t ignite. What part is bad?
Furnace won’t ignite after the draft inducer runs = failed igniter. The hot surface igniter should glow bright orange within 60 seconds. No glow = cracked/burned out. Weak glow = degrading. Average lifespan: 3–7 years. Replacement: $15–$40 DIY.
Is this igniter 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 igniter?
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.
