Whether you’re hosting a dinner party or heating up some leftovers it can be frustrating when your Thermador range burner won’t light. We’ll discuss some simple solutions when your Thermador gas range burner doesn’t light such as loose electrical connections and dirty burner components. We’ll also review when a professional repair may be necessary.

What to Do When your Thermador Range Burner Won’t Light

When troubleshooting an appliance malfunction it’s helpful to rule out the simplest causes first. Even a superior range like Thermador benefits from oven maintenance tips and basic care to operate at its best. To save time, our guide for a Thermador range burner not working starts with the most basic reasons before discussing a potential repair.

Check Power and for Loose Connections

Even though you have a gas range, your Thermador range burner will not ignite without electricity. This is because the burner igniters require electricity to spark and ignite the burner. Here are some simple checks you can make to ensure your range is receiving electrical power:

  • Check your circuit breakers to make sure that the breaker for the range hasn’t tripped and there are no blown fuses.
  • Move the stove away from the wall to ensure it’s still plugged in properly
  • Refrain from using an extension cord to operate your range. A typical extension cord won’t safely accommodate the power needed for a stove.

Clean the Defective Burner

Oftentimes, dirty burner mechanisms are responsible when your Thermador range burner won’t light. This occurs when accumulated cooking debris clogs parts or inhibits the flow of gas. These step-by-step Thermador range cleaning instructions review how to clean Thermador star burners and their components:

How to Clean the Burner Base

  1. Make sure the cooktop is cool.
  2. Remove the star burner cap and set aside.
  3. With a soft cloth or sponge, use warm water and mild dish detergent to clean the base area.
  4. Use a toothbrush to gently clean out the burner base gas ports, refraining from scrubbing or scratching.
  5. Dry the area thoroughly with a clean cloth.

How to Clean the Burner Cap

  1. Lift up the star burner caps.
  2. Gently scrub with a soft cloth or sponge, warm water and mild dish detergent. Don’t soak burner caps.
  3. Rinse under warm running water.
  4. Dry caps thoroughly before replacing.

How to Clean the Igniter

  1. Dampen a Q-tip with water, taking care not to soak it.
  2. Use the Q-tip to gently wipe away any debris on the igniter.
  3. Carefully scrape away any stuck-on debris with a toothpick.
  4. Make sure igniter is completely dry after cleaning, as a damp igniter won’t spark the burner.

Replacing a Broken Range Igniter

If your Thermador range burner won’t light after following these troubleshooting steps then it’s possible that the igniter has failed. A functioning igniter works by heating up with electrical current, producing a spark that lights the flow of gas when it reaches a certain temperature. As soon as the flame ignites, the electricity to the igniter shuts off automatically.

A malfunctioning igniter may have too weak a spark to light the gas or no spark at all. You may hear the igniter clicking but the burner won’t ignite. A faulty range igniter cannot be repaired and requires replacement. If you’re not well versed in DIY appliance repair, we suggest a professional service for this job.
