Electric ovens do not have an igniter. However, modern gas stoves use igniters or electrodes to light surface burners and oven burners. Some gas ovens use a glow coil to ignite the gas, which stays on the entire time the flame is lit. The igniter in these ovens is a glowbulb that heats up to a temperature that will ignite any gas that touches it.

What You'll Learn
Electric ovens do not have igniters
In contrast, electric ovens do not require igniters as they do not use gas. Instead, electric ovens use heating elements to generate heat. These heating elements are typically controlled by a thermostat or electronic control, which regulates the temperature inside the oven.
It is important to note that some ovens may be dual-fuel, meaning they have both gas and electric components. In such cases, the oven may have an igniter for the gas burners, but the electric components will not require an igniter.
If you are experiencing issues with your electric oven not heating properly, it is recommended to consult a qualified technician or refer to the oven's user manual for troubleshooting steps. It may be necessary to replace the heating elements or thermostats to resolve the issue.
Additionally, for those living off-grid or looking for alternative power sources, there are options available. Some older oven models use standing pilot lights that can be lit with a match or lighter, eliminating the need for an electric igniter. However, these models may be less efficient and may not have the same safety features as modern gas ovens.

Gas ovens use electric igniters
Electric ovens do not have igniters. However, gas ovens use electric igniters. These igniters are usually sparking igniters or glow bar igniters. Sparking igniters use automatic spark control, which can be based on knob position. Glow bar igniters, on the other hand, monitor the current through the glow strip to know when the strip is hot enough to open the gas valve.
While gas ovens with sparking igniters are preferred for off-grid homes, they are harder to come by. Most modern ovens use glow bar igniters, which stay on as long as gas is burning. However, some ovens have glow bars that only come on when heat is needed in the oven. Once the desired temperature is reached, the gas and the glow bars shut off until more heat is required.
The power consumption of gas ovens with electric igniters can be quite high, sometimes drawing around 500 watts when the oven is on. This has been a cause for concern for those seeking more energy-efficient cooking options.
It is important to note that the specific type of igniter and its power consumption may vary across different oven models and brands.

Older gas ovens use standing pilot lights
Electric ovens do not have igniters.
In newer gas stoves, the standing pilot light has been replaced by electronic ignition systems, which offer a more advanced and efficient way of igniting the gas flow. These systems create a spark when the appliance is turned on, igniting the gas released by the gas valve. This eliminates the need for a constant flame in the pilot light area, making it safer and more energy-efficient.
Some gas stoves and ovens use a glow bar ignition system, another type of electronic ignition. In this system, an electrically heated element, known as a glow bar, gets hot enough to ignite the gas. This method is prevalent in gas ovens and provides a reliable and efficient way to start heating.

Modern gas stoves use ceramic igniters or electrodes
Electric ovens do not have igniters. However, modern gas stoves use auto-ignition systems, which commonly include ceramic igniters or electrodes. These systems allow burners to light automatically using electricity, eliminating the need for manual ignition with matches or lighters.
The auto-ignition system uses piezoelectric igniters, which are made from specialised piezoelectric crystals, usually zinc oxide or quartz, encased in a ceramic housing. When the control knob is turned, mechanical force is applied to the crystals, generating voltage through the piezoelectric effect. This voltage travels through a wire to the electrode tip, placed within 1-3mm of the burner outlet. When the high voltage reaches the electrode, it arcs across the small gap to the burner, creating a spark that instantly ignites the gas.
The entire ignition process is extremely fast, allowing the burner to ignite within a fraction of a second. This speed and convenience are the major advantages of auto-ignition systems compared to manual ignition. Auto-ignition also ensures safety by eliminating the need for an external flame source.
The electric stove igniter, also known as a spark igniter, is another type of igniter used in gas stoves. It creates a spark of electricity between two metal electrodes to ignite the gas. Standard electric igniters, commonly found in older models, have a wire extending from the gas valve to the igniter. When the oven is turned on, the igniter receives an electric current and produces a spark.
It is important to note that gas stove igniters require regular maintenance and cleaning to function correctly. Food particles and debris can build up over time, affecting their performance. Therefore, it is recommended to clean the igniter gently with a cotton swab or soft-bristled brush and ensure that all parts remain in their correct positions.

Igniters can be replaced
While electric ovens do not have igniters, gas ovens do. If your gas oven is not working, it may be due to a faulty igniter. In such cases, you can replace the igniter yourself or hire a professional to do it for you.
Before replacing the igniter, ensure that you have the correct replacement part. You can purchase replacement igniters at major hardware retailers and online stores. Make sure to double-check that you are buying the right part for your specific oven model.
Once you have the correct part, follow these steps to replace the igniter:
- Open some windows and doors in the kitchen to ensure proper ventilation. This is important because small amounts of gas will likely seep out during the process, which can be a health risk.
- Ensure that your oven is cool before starting any work.
- Remove all racks, trays, and the bottom panel from the oven. The bottom panel is usually held in place by screws, which need to be unthreaded. You may also need to remove the internal part of the oven door to access the igniter, depending on your oven model.
- Locate the igniter and disconnect it. Before beginning this step, make sure the range is unplugged and the gas supply is turned off to avoid any accidental ignition. The igniter is typically connected to the range with a wiring harness or individual wires. Take a picture of how the wires are connected to the igniter so that you can replicate it when installing the new one. Gently pull the wires apart, holding the connectors instead of the wires themselves. Avoid using excess force as this can damage the wires.
- Install the new igniter by connecting the wires to the new igniter, following the picture you took earlier as a guide.
- Reassemble the oven by screwing the bottom panel back into place and placing the racks and trays inside.
By following these steps, you can safely and effectively replace the igniter in your gas oven.

Frequently asked questions
No, electric ovens do not have an igniter.
Most modern gas ovens use igniters or electrodes to light burners. Older gas ovens use standing pilot lights.
If your igniter is not working, you should first check if it is glowing. If it is glowing but the burner is not lighting, the igniter may be weak or faulty. In this case, you should have a qualified person verify if the igniter is defective and then replace it.
