This Part Fixes These Problems

Burner Won't Ignite

Gas burner fails to light or does not stay lit when the igniter button is pressed; clicking is heard but no spark reaches the burner.

Delayed / Slow Ignition

One or more burners take several seconds longer than normal to ignite, indicating a weakened or deteriorating spark electrode.

Intermittent or No Sparking

Spark from one burner is erratic, fires to the wrong side, or is completely absent even though the spark module and wiring test good.

Cracked or Broken Ceramic Insulator

Visible crack, chip, or fracture in the ceramic body of the ignition plug causes spark leakage and unreliable ignition performance.

Continuous Clicking After Lighting

Burner continues to click and spark after the flame is established, often caused by a damaged insulator or carbon-tracked electrode surface.

💡 Pro Tip: How to Diagnose a Failing Burner Igniter

Your part is likely the culprit if you notice any of the following:

⚠️ Gas burner will not ignite or fails to stay lit after repeated attempts

⚠️ Delayed ignition — burner takes several seconds longer than normal to light

⚠️ Intermittent or completely absent sparking from one burner position

⚠️ Visible crack or chip in the ceramic insulator of the ignition plug

🛠 Before condemning the igniter, verify the burner head and cap are clean and dry — food residue or moisture can cause continuous or absent sparking that mimics a failed electrode. Use a multimeter to confirm continuity on the igniter wire from the spark module. If wiring checks out and cleaning does not help, replace the ignition plug assembly (189324).

Questions & Answers

Will this 189324 ignition plug fit my Thermador SGS365 cooktop?
Answered by Support Team  ·  Mar 15, 2024
Yes. Part 189324 is the correct ignition plug assembly for the Thermador SGS365 series. It is a direct, confirmed-fit replacement for that cooktop line. Always verify your full model number before ordering to ensure exact compatibility.
Does the 189324 come with the retention clip or C-spring needed for installation?
Answered by Support Team  ·  Nov 20, 2023
The ignition plug assembly is sold individually and does not always include the small C-clip or retention spring. If your original electrode uses a retention spring (part# 00419187), you should order it separately. The spring simply pulls off the old plug and slides onto the new one.
My burner keeps clicking after it lights. Will replacing part 189324 fix it?
Answered by Support Team  ·  Jan 8, 2025
Continuous post-ignition clicking can be caused by a carbon-tracked or damaged ceramic insulator on the ignition plug, moisture around the burner head, or a failing spark module. Start by thoroughly cleaning around the electrode with white vinegar and a toothbrush and ensuring the burner head is fully dry. If the issue persists after cleaning, replacing the 189324 electrode is the next step. If clicking continues after the new igniter is installed, test spark module 00619017.
Is the 189324 ignition plug compatible with Gaggenau cooktops?
Answered by Support Team  ·  Jul 22, 2024
Yes. The 189324 / 00189324 ignition plug assembly is manufactured by BSH (Bosch-Siemens Hausgeräte) and is shared across the Bosch, Thermador, and Gaggenau appliance families. The Gaggenau CD456U is a confirmed compatible model. Check your specific model and serial number for final verification.
How do I test my ignition plug to confirm it needs replacement before ordering?
Answered by Support Team  ·  Feb 10, 2026
First, visually inspect the ceramic insulator — any visible crack, chip, or carbon tracking means the plug must be replaced. Next, use a multimeter to check continuity on the wire running from the spark module to the igniter terminal. If the wire has continuity and the burner head is clean but there is still no spark, the 189324 ignition plug assembly is almost certainly the failed component and should be replaced.
