Fixing A Thermador Gas Cooktop That Won’t Spark

One of the most common problems with a Thermador gas cooktop is that the ignitor won’t spark and ignite the burner or element. 

However, while this can be extremely frustrating, it’s usually caused by minor issues that you can often resolve on your own.  

So, before you throw in the towel and call it quits, there are a few things you can try to get your cooktop working again. 

Keep reading to learn more about fixing a Thermador gas cooktop that won’t spark. 

But first, it’s essential to know that you shouldn’t try to repair a gas appliance on your own. Gas appliances pose a serious risk for those who don’t know what they’re doing. And, if you don’t fix the problem correctly, you could end up injuring yourself or someone else in the process. 

So, if you’re having a serious issue with your gas appliance, don’t hesitate to get in touch with a professional technician today. A good repair technician will have your cooktop working again in no time.

Common Issues With Gas Cooktops

As your Thermador gas cooktop ages, it requires maintenance and repair to keep it in good working order. If not, you’re bound to run into problems and frequent breakdowns that I’m sure you’d rather live without.

Clean The Burner Caps

One of the most common reasons why a Thermador gas cooktop won’t spark and ignite is simply because the burner is dirty. Over time, food particles can build up and clog the burner, which will interrupt the flow of gas that the burner needs to ignite and hold a flame.

In short, you should clean your burners thoroughly at least once a month and give your gas cooktop a wipedown after every single use. This will prevent food particle build-up and ensure that the gas can flow freely. 

To clean your gas burners, all you need is hot water and some dish soap. Soak the burner caps, and check the fuel ports for debris. If needed, you can use a small needle or toothpick to try and dislodge and residue built up in the holes.

Ensure Your Burner Cap Is Properly Positioned

Your Thermador gas cooktop sometimes won’t spark simply because the burner cap isn’t correctly positioned, which will prevent the arc from igniting the flow of gas

The burner cap needs to rest in the correct position on top of the fuel port to properly disperse the flow of gas. 

Therefore, if the burner isn’t positioned properly, it could block the flow of gas, and your cooktop won’t ignite.

To fix the issue:

1. Turn the power to your gas cooktop off.
2. Lift the burner cap and reposition properly it over the fuel port.
3. Turn the cooktop on again and test the burner. If correctly positioned, the cooktop should spark and ignite your burner

If your Thermador gas cooktop still doesn’t spark, don’t hesitate to reach out to a professional appliance repair service to get the problem diagnosed and repaired quickly and safely. 

Ensure The Circuit Breakers Aren’t Off

It might be obvious, but just like an electric stove, gas cooktops also need electricity to work properly. Therefore, if your cooktop isn’t sparking, it might mean that a circuit breaker has been tripped, or that you have a faulty outlet or power cord. 

To check your circuit breakers:

1. Go to your circuit breaker panel and open the panel. 
2. Look for the breaker that your cooktop is connected to. If this is the issue, you should see a breaker in the ‘off’ position.
3. Turn the switch ‘on’, and then check to see if you’ve resolved the issue.

Igniter Replacement

If your Thermador gas cooktop is older, it might be time to replace the ignitor. This is a very common reason that a cooktop might not spark, which is, fortunately, relatively easy to repair.  

The cooktop’s ignitor is the component that actually produces the spark that ignites the gas. So, if this part of the cooktop is broken, you will need a new one.

Replacing an ignitor isn’t overly complicated. But to ensure that the job is done properly, it’s best to call in a professional technician. They have the right tools to identify the root of the problem and get your cooktop back to working order!

Malfunctioning Spark Module

If your Thermador gas cooktop sparks erratically, you can be sure that you have a malfunctioning spark module. 

You can sometimes fix the issue by turning off the power to your cooktop and cleaning the igniter. However, if your spark module continues to malfunction, don’t delay.

Damaged Control Board

The control board is the electrical component of your Thermador gas cooktop that controls everything it does. For example, when you set the burner temperature, the control board will tell the cooktop to increase (or decrease) the flow of gas to match your input. 

If the control board is damaged, it might be the reason you cooktop isn’t sparking.

With that said, replacing a damaged control board takes a solid working knowledge of Thermador gas cooktops. If you don’t have experience in this type of appliance repair, it’s best left to a professional.
