Are you wondering why your oven won’t turn on? If so, this can be a frustrating problem. You probably rely on your oven on a regular basis. If your oven won’t turn on, this could prevent you from cooking dinner for yourself and your family. 

In general, problems related to your oven not turning on can be divided into electrical and mechanical issues. There could be a faulty part that is preventing your oven from turning on, and there could be something wrong with the electrical system.

The sooner you can figure out what the problem is, the faster you can fix it. We have done an incredible amount of research to figure out the most common reasons why an oven won’t turn on. There is a good chance that the reason why your oven won’t turn on is one of the reasons below. Therefore, take a closer look at a few of the reasons below, and remember to reach out to a professional if you have concerns about your oven.

The Most Common Reasons an Oven Won’t Turn On

Some of the most common reasons why an oven will not turn on include:

1. There Is a Problem with the Bake Element

One of the first reasons why your oven might not turn on is that there is something wrong with the bake element. The bake element is responsible for generating heat for the rest of the oven. When this element is working properly, it should glow red hot. If the element is not blowing properly, it is a sign that the oven is not heating. 

If the heating element has become burned out, it might be physically damaged. Therefore, you may want to take a look at the bake element for signs of blisters or holes. You may also want to use a multimeter to test the electricity going through the bake element. If you stop at your bake element and it has a lot of holes in it, or if you find that it is not conducting any electricity, this is a sign that it is dead. 

If there is something wrong with your bake element, then you need to replace it. You should take a look at the manual to figure out what type of bake element you need. Then, you should take a look at how expensive the bake element is to figure out if it is actually worth it to repair or replace it. There are some situations where it may be better to get an entirely new oven.

2. The Igniter Is Dead

If you have a gas oven, then one of the most common reasons why it might not be behaving appropriately is that something is wrong with the igniter. The igniter is one of the most important parts of the gas oven because it draws an electrical current through the safety valve, opening it. Second, the igniter is responsible for igniting the gas in the burner. If the igniter is faulty, then it will not turn on the oven. 

The figure out if there’s a problem with the igniter, you should take a look at it when you turn the oven on. Does the igniter look like it is doing anything? Or, does it look like it is having a difficult time getting the oven to turn on?

Similar to the bake element, you need to think about whether it is worth it to replace the igniter. Because you are dealing with an open gas source, you need to make sure you shut off gas to the oven before you work on the igniter. If you do not have experience working with a gas oven, then you may want to reach out to a professional who can address this problem for you. 

3. Something Is Wrong with a Spark Electrode

Another possible reason why you might be having a difficult time getting your oven to turn on is that something is wrong with the spark electrode. There is an electrode that sits right next to the burner. In essence, this is a spark plug, causing the spark to jump from the electro to the shield, igniting the gas. This gets your oven to turn on. 

If there is something wrong with the electrode, then the oven is not going to light properly. You should take a look at the electric assembly system to see if there are any cracks present. Usually, your electrode is sitting in a porcelain house. If there are cracks in the housing system, the electrode will not behave properly. 

You may also want to use a multimeter to test the electrode. If you do not get any current going through the electrode, then you may need to replace it. Fortunately, this is usually not an expensive fix. At the same time, you may want to hire a professional to do this properly.

Even though replacing the spark electrode might seem like a quick fix, it would be safer it the repair is performed by a qualified technician.

4. The Thermal Fuse Has Blown

Your oven has a defensive mechanism that prevents it from overheating. If the thermal fuse senses that your oven is overheating, it will trip, causing the oven to turn off. If the thermal fuse has already blown, then the oven is not going to turn on because it will sense there is no safety measure in place.

Another reason why your oven might not be turning on is that the thermal fuse is tripping when it should not. In this case, the thermal fuse has gotten a bit overzealous, preventing the upper from turning on before you even start cooking. This is another potential issue with the thermal fuse that you need to address. 

Regardless, you should take a look at the thermal fuse using a multimeter. If you find that a thermal fuse does not have any power going to it, then it is not working properly. As a result, you will need to replace it. 

You should take a look at the manual to see what type of thermal fuse you need. That way, you can get the best one for your oven. 

5. The Oven Control Board Is Not Behaving Properly

The next place you may want to look at the control board of your oven. Essentially, this is the motherboard of your appliance. It has a wide variety of relays that are responsible for sending signals to the various functions of the oven. This includes your baking system, your broiling system, and any other settings you might have. 

If you have a defective control board, is not going to send signals to the rest of the oven. This is a very rare problem with an oven, so you need to look closely to make sure this is the issue. It has a wide variety of components, and you need to test all of them individually before you determine if you need to replace the oven control board. 

If you do need a new control board for your oven, you need to take a close look at the total cost of this repair. Because this is such an integral part of an oven, it may be better for you to get an entirely new oven instead. 

6. The Gas Safety Valve Has Failed

Furthermore, you should take a look at the gas safety valve as well. The safety valve is responsible for preventing gas from flowing into the oven when it is not in use. You do not want gas going to the oven when it is not turned on because this creates a significant safety issue. 

If the safety valve has failed, the oven is not going to heat. The safety valve might not open, so gas cannot flow to the oven. Without gas going to the oven, you cannot cook anything.

Similar to the oven control board, this is a very unusual problem with an oven. Therefore, you should take a look at all the other parts before you settle on the gas safety valve.

If you do need to test the gas safety valve, you need to use a multimeter. It should have power flowing to it. If you do not have any power going to the safety valve, then you need to replace it. 

Even though this is not a particularly hard replacement, it can be difficult for you to find the right safety valve. You need to take a look at the manual to see what type of safety valve you require. Then, you need to make sure it works properly before you turn on the oven again.
