The gas igniter is an electrical device that is used to ignite the gas burner. The heating of the oven starts when current supplied to the igniter turns on a glowing filament inside it, which burns at high temperature; as a result, the gas is ignited.
How does an ignitor work on a gas stove?
Electrical current passing through the ignitor operates a small heater that warps an internal piece of bimetal to open the gas valve. As long as the burner flame continues to heat the ignitor, its electrical resistance remains low enough to keep the valve turned on.
What does it mean when your oven Ignitor is glowing?
As long at the ignitor is being powered, the control system (hydraulic thermostat or electronic control) is doing its job. The ignitor, while glowing, may not be allowing the proper amount of current to flow through it to the oven gas valve for it to open.
Where is the bake ignitor on a gas oven?
Note: The bake ignitor is normally hidden under the oven floor, which is easily pulled up and removed. There's usually a steel 'flame spreader' on top of the burner, which is also removed to access the bake ignitor. In ovens with an exposed broil ignitor (up on the oven ceiling), it's possible to confuse the two and replace the wrong one.
How does a gas oven work?

Do gas stove igniters wear out?
The igniter on your gas oven is a fundamental part when it comes to heating your oven up. A gas oven igniter works by sparking and heating the gas emitted from the oven, so without it, the oven will not be able to produce heat. However, as so much rests on this little igniter, they are prone to a bit of wear and tear.
How long should it take a gas oven to ignite?
approximately 30 to 45 secondsAnswer: Gas oven burners ignite in approximately 30 to 45 seconds. The infrared broil burner will light within 45 seconds. If it takes much longer than this to ignite, the burner may be experiencing delayed ignition, refer to Gas Oven Delayed Ignition for more information.
Why does my gas oven take so long to ignite?
A: The likely issue is a weak or failing oven igniter. Heat resistance igniters can lose resistance as they get hot over time and won't send enough resistance to the gas valve to allow the main valve to come on. This intermittent starting can happen when the igniter is getting weak and before it goes completely out.
How do I clean the igniter on my gas stove?
The igniter is situated at the gas orifice, which is often at the back of the oven. Use the toothbrush and a paste of baking soda and water or a 50/50 vinegar solution to clean the surface of the igniter. Avoid cleaners with bleach, ammonia or any other chemical that could produce noxious fumes.

Why does my gas stove work but not my oven?
If the gas igniter is working, the problem might be that the gas elements or burners are blocked. The easiest way to check them is to take them out and check that they aren't blocked in any way. If they are, give them a clean and then put them back into the oven and see if this solves the problem.
What is an ignitor in a gas oven?
The Gas Oven Ignitor. Ignitors used on gas ovens today need to be able to handle very high temperatures. They are made of silicon carbide making them capable of dealing with the intense heat. They are called ignitors but in reality they are electrically in the circuit anytime the burner is burning not just at ignition.
Why does the gas in my oven flex?
The increase in current flow within the circuit heats the bimetal inside the oven safety valve causing it to flex just enough to allow gas to flow into the burner assembly. Once the gas passes through the burner assembly and comes in contact with the now glowing red hot ignitor it ignites.
What is the bracket on a gas burner?
Most of the time the burner assembly has a bracket attached where the ignitor is mounted. This maintains the proper distance between the ignitor and the burner assembly to ensure proper ignition of the gas.
What is a burner assembly?
The burner is simply an aluminum tube that has been machined and drilled with precise outlets spread along the length of the tube to allow the flame to burn from one end of the burner, sometimes in the front and down the other side.
How does an oven safety valve work?
Oven safety valves used on today's modern gas ranges are designed to prevent gas from flowing to the burner assembly in the event that the igniter is not hot enough to ignite the gas, or if no electricity is present. Inside the oven safety valve is a strip called a bimetal that when not heated forces the gas valve closed. As mentioned before the igniter is electrically in series with the oven safety valve. Electricity flows from the control whether that be a thermostat or an electronic control whenever the oven is requesting a higher temperature. The electricity enters one side of the safety valve passing through the bimetal. When it comes out the other side it passes directly through the oven ignitor. As the oven ignitor heats up its resistance goes down causing the current flow in the circuit to increase. The increase in current flow within the circuit heats the bimetal inside the oven safety valve causing it to flex just enough to allow gas to flow into the burner assembly. Once the gas passes through the burner assembly and comes in contact with the now glowing red hot ignitor it ignites. As long as electricity is flowing through the igniter and the igniter is drawing sufficient current, the bimetal in the oven safety valve will stay flexed open allowing gas to flow.
What are the components of a gas oven?
The main components of a gas oven system are the safety valve, the burner assembly, the igniter, and some form of control. The control can either be a thermostat that we all are accustomed to, or an electronic control.
Why is my gas oven not glowing red?
That's because unlike in the past where most gas ranges and wall ovens used a freestanding pilot light, today's gas ovens rely on an oven safety valve that will not permit gas to flow to the burner unless the igniter is glowing red producing enough heat to ignite the gas when it reaches the igniter. And of course, the oven ignitor will not glow red ...

What is a spark ignition system?
The spark ignition system is actually a two-level system. The spark module produces an extremely high voltage with very low amperage. The spark produced is used to ignite a low-pressure gas flow to a flame pilot light that remains lit until the oven’s thermostatic control is turned off. The pilot flame remains lit to ignite the gas flowing through the burner bar as the oven cycles on and off to keep it at the preselected temperature.

How to tell if an igniter is bad?
Most often, appliance owners are able to diagnose igniter problems through noise alone. By listening to your gas oven , you can actually tell if igniter problems are coming. Obviously, the most concrete sign is when your oven isn’t producing heat. As there is no electric element in a gas oven, when the igniter doesn’t work, the oven can produce no heat. Though often, signs of the igniter going outcome before this happens.
Why does my oven make a clicking noise?
One other noise to look out for is excessive clicking. Like gas burners on your stove, the oven igniter may click when it is trying to ignite the gas. However, if it keeps clicking, this means the igniter isn’t lighting the gas, but it is still trying.
What happens when the igniter doesn't work?

How does an ignitor work?
Electrical current passing through the ignitor operates a small heater that ‘warps’ an internal piece of bimetal to open the gas valve. As long as the burner flame continues to heat the ignitor, its electrical resistance remains low enough to keep the valve turned on. If, for any reason, the flame is extinguished, the igniter's resistance increases and the valve turns off the gas to the burner.
What type of ignition is used in a gas oven?
Most gas oven systems today are ‘electronic ignition’, and use a ‘glowbar’ type ignitor electrically in series with an oven valve.
What happens if your oven doesn't light?
If your oven doesn’t light, but you see the ignitor glowing, it will most likely be glowing a very dull red and not drawing enough current to operate the valve. Or, in some cases, it will operate the valve very slightly and you’ll smell some gas odor. Neither case is desirable or acceptable!
What happens when a gas flame is extinguished?
If, for any reason, the flame is extinguished, the igniter's resistance increases and the valve turns off the gas to the burner. While the valves are very reliable, the igniters have become the most common parts failure on these systems. Which is to be expected, I guess; they’re doing their job in a gas flame!
What to do if there is no glow in my ignitor?
If there’s no ‘glow’ at all, take a close look at the ignitor, and you’ll often see a crack, or it may even be obvious that it’s broken apart. You can use an ohmmeter to test for continuity if no cracks are visible.
How long does it take for an ignition to light?
If it takes more than 2 minutes to light, you’ll want to replace the ignitor; it’s the culprit in 90% of these. And this is the best way for you to diagnose your ignition system! In most cases, that’s all there is to it. You don’t even have to worry about wire polarity on the new ignitor – they can be wired either way.
Can ignitor be interchanged?
Igniters come in two basic types, ‘flat’ and ‘round’, seen below, and they can’t be interchanged. Each type operates at a particular amperage level, and is matched to the type gas valve it operates.
