Thermador Igniter Parts

Thermador Range Igniter Parts

Thermador's pro-style ranges demand precision igniters that match the Star burner design and exact voltage specs. When your Thermador oven won't heat or the igniter glows orange then dies, you need an OEM replacement — aftermarket igniters often fail to meet Thermador's engineering tolerances.

We stock genuine Thermador igniters for all current and legacy models. Verify your model number and the igniter type (silicon carbide vs. Silicon nitride) using our lookup tool — Thermador igniters aren't universal, and getting the wrong type wastes time and money.

• Oven igniter won't glow: igniter filament is broken; no spark means no gas valve trigger
• Igniter glows but goes dark: weak igniter can't maintain heat to open the gas valve
• Igniter glows orange instead of white: signs of a failing element; replacement needed within days
• Oven heats inconsistently: igniter heat cycle is weak; intermittent ignition leads to uneven baking
• Igniter cracks or pops: thermal stress; cracked igniter is a fire risk and must be replaced immediately

Thermador Igniter Replacement FAQ

What's the difference between silicon carbide and silicon nitride igniters?

Silicon carbide (SiC) igniters are older and more fragile — they're thinner and prone to cracking from thermal shock. Silicon nitride (SiN) igniters are newer, tougher, and last longer. Your Thermador model number determines which type you need; using the wrong type won't fit the bracket or trigger the gas valve correctly.

How do I know if the igniter or the gas valve is the problem?

If the igniter glows bright white and stays hot, the igniter is working — the gas valve is likely the issue. If the igniter barely glows, flickers, or goes out quickly, the igniter has failed. You can test igniter resistance with a multimeter (should read 40 to 60 ohms when cold); zero ohms or infinity means replace it.

Can I clean a Thermador igniter instead of replacing it?

Unlike flame sensors, igniters cannot be cleaned effectively. The ceramic element either conducts electricity properly or it doesn't. Cleaning a weak or cracked igniter is a waste of time — OEM replacement is a primary reliable fix.

Why is my Thermador igniter failing so quickly?

Thermal cycling stress is the #1 cause. Each time your oven heats and cools, the ceramic expands and contracts. If the igniter bracket is loose, allowing too much movement, the igniter cracks prematurely. Check the mounting hardware and bracket alignment when you replace the igniter — a secure fit extends igniter life.

Thermador Range Model Number: Where to Look

On Thermador ranges, look for the model number on the rating label along the oven door frame or inside the oven door. Depending on the model, the label may also be behind the lower storage drawer, so remove the drawer if the number is not visible with the door open. Record the complete model number, including any letters, numbers, and slash marks. Use it in the model number search to pull up the parts matched to your unit, not just a replacement igniter. The model number filters the full Thermador range parts catalog, helping you identify parts that fit your specific appliance. That means fewer wrong orders and a faster repair.
