How do gas stoves work: a complete guide

What is a gas stove?

A gas stove is a culinary appliance that utilizes gas to create an open flame for cooking. These appliances come in various configurations, and exploring the different types of ranges can help you find the ideal fit for your kitchen layout. Different types of gas burners on the stovetop offer various heat levels that allow you to have optimal control over cooking temperatures. For instance, standard burners typically provide anywhere from 8,000 to 12,000 BTUs, which is suitable for everyday cooking tasks like pan-frying. Select Whirlpool^® models such as this gas range feature the FlexHeat^™ Burner, with two rows of flames that give you the evenly distributed high heat you need for rapid boiling and searing or the lower temperatures necessary for more delicate dishes.

When considering different types of cooktops, gas options remain popular for their responsive temperature adjustments. And adding accessories can help you expand your dinner time possibilities. For instance, a griddle is a versatile cooking tool that provides a level cooking surface, ideal for foods vulnerable to high heat. Select Whirlpool^® Gas Ranges feature a 12,000 BTU Griddle Zone, with one long, oval-shaped burner that makes it easy to cook up all that delights, all at once.

In the oven cavity of a gas stove, the flame cycles on and off to maintain ideal cooking temperatures for baking and roasting. Because these appliances involve gas, it is important to use proper ventilation, such as a range hood, to help maintain indoor air quality while cooking. This helps ensure a comfortable environment while you prepare meals for your family.

Parts of a gas stove

Understanding the various parts of a stove can help you maintain your appliance and troubleshoot minor issues. A standard gas range consists of several key components designed to work together seamlessly. Some of the primary parts of a stovetop include:

• Burners: The components that distribute the gas to create a flame.

• Burner caps: Removable covers that help distribute the flame evenly across the bottom of your cookware.

• Removable grates: The heavy-duty supports that hold your pots and pans above the flame. Select Whirlpool^® Gas Ranges feature Edge-to-Edge Grates so you can enjoy plenty of space.
• Knobs: The controls used to ignite the burners and adjust the flame intensity. Select Whirlpool^® Gas Ranges feature Dishwasher-Safe Knobs that make cleanup easy.

To help keep your appliance looking its finest, you can soak grates in an ammonia-based cleaner sealed in a plastic bag overnight, then rinse with soap and water. Some Whirlpool^® Gas Ranges feature EZ-2-Lift^™ Hinged Cast-Iron Grates that give you quick access to spills on the cooktop. The hinged design lets you wipe up underneath without removing them.

Along with the stovetop elements, gas ranges feature an oven cavity for baking and roasting. These lower sections often include oven racks for positioning food and electronic control panels to set baking modes. Some models also feature warming drawers to help keep finished dishes at an optimal temperature.

How do gas stove igniters work?

Gas stoves use different ignition systems to light gas for both the cooktop and oven. To understand how a gas stove works at its core, it helps to know that cooktop ignition is almost instant, while with oven ignition, you naturally have to take into account the time the oven takes to reach the target temperature after ignition. 

Ever wonder what happens when your gas stove clicks? Here is how it works in three quick steps:

• The Switch: Turning the knob to "Lite" flips an internal electrical switch, sending power to a hidden component called a spark module.

• The Boost: The module acts like a spring, instantly cranking up the electrical voltage so it is strong enough to jump through the air.

• The Spark: This electricity travels to the ceramic igniter tip next to the burner and leaps across the gap to the metal cap. That leap creates the blue spark—and the rhythmic click-click-click sound.

The moment the escaping gas hits that super-hot spark, it catches fire. Turning the knob past "Lite" cuts the electricity and stops the clicking so you can get cooking. Cooktop burners create and distribute heat immediately upon ignition. 

Oven burners operate on a similar principle but are enclosed within the appliance cavity. When you set a baking temperature on some models, the oven igniter glows red hot to open the gas valve. Once the gas flows, the igniter lights the flame. This enclosed system is designed to provide consistent heat distribution for baking and roasting your favorite family recipes. On other models, a high-voltage electric spark is used to light the oven burners.

How does the oven in a gas stove work?

If you’re wondering how ovens work—and specifically how does a gas oven work—it has to do with heat and cycling. In a gas oven, the flame cycles on and off to maintain ideal cooking temperatures throughout the baking process. Ovens generally work by using two separate heating elements or burners to cook food, allowing you to brown, crisp or gently bake dishes depending on rack placement.

When you start a recipe, you turn the oven to a specific temperature and the oven begins to preheat. This allows the oven cavity to reach the target temperature before you insert your food. Once heated, the lower bake burner provides the primary heat source, while the upper broil burner can be used for targeted top-down heating.

Heat distribution within the oven cavity impacts how your food is prepared. Traditional thermal baking relies on natural air circulation, which is suitable for most recipes. Some models feature Convection Cooking, which uses a fan to circulate hot air throughout the oven. This continuous airflow helps eliminate cold spots and promotes even baking across multiple racks, making it an excellent choice for achieving a golden-brown finish on roasted meats. Select Whirlpool^® Gas Ranges feature True Convection with Third Heating Element, which cooks food with the addition of a third element plus a fan that distributes hot air evenly over, under and around food so dinner is ready when you are.

Gas stove FAQs

When exploring gas cooking appliances, you may have questions about their operation and capabilities. Below are answers to some common inquiries about gas stoves.

Do gas stoves use electricity?

Many people ask: do gas stoves use electricity? Yes, modern gas stoves require electricity to operate the electronic ignition systems, control panels and oven lights. While the primary fuel source for heating is gas, an electrical connection is necessary to power the igniters to light the burners on the stovetop and inside the oven. 

Can I use a gas stove during a power outage?

Using a gas stove during a power outage depends on your specific model and its features. A gas oven is usually unusable during a power outage, but a gas cooktop may possibly be used by manually lighting the surface burners, but this depends on the model and may be blocked by certain appliance features. Check your user manual to be sure.

If it is doable on your model, try these steps to light a surface burner manually. First, hold a lit match near the burner and turn the knob to the ignition position. Then, adjust the flame. However, the gas oven cannot be used without electricity because it requires an electric ignition system to function properly. Always consult your owner's manual for model-specific guidance before attempting to manually light your appliance.

What type of gas do gas stoves use?

Gas stoves are designed to operate using either natural gas or liquid propane (LP). Most residential gas ranges come factory-configured for natural gas, which is supplied through a municipal utility line. If your home uses liquid propane from a dedicated tank, the appliance must be converted using an LP conversion kit, which is typically included with the stove or available for purchase separately, and should be installed by a professional.

Why is my gas stove clicking but not lighting?

If your gas stove is clicking but failing to ignite, a common culprit is a misaligned burner cap or moisture trapped in the burner ports. This often happens after cleaning the cooktop or following a spill. Ensure the burner cap is seated correctly and the area is completely dry. If the issue persists, there may be a blockage in the gas tube or a faulty igniter switch that requires professional maintenance.
