A Kenmore oven needs around 10 minutes to reach its set temperature, regardless of whether it’s a gas or electric model. When that doesn’t happen, or the oven doesn’t heat up, you’ve got a problem that needs troubleshooting.
Your Kenmore oven won’t heat up if it has no power supply, even for gas models. The same will also happen if the igniter on gas models is weakened and needs to be replaced. For gas and electric models, a failed thermostat or faulty main control board can cause these heating problems.
This guide will help you figure out why your Kenmore oven isn’t heating. As you read through to the end, you’ll understand why it’s happening and what you can do about it.
Why Is My Kenmore Oven Not Heating?
Kenmore gas and electric ovens only need a few minutes to heat up.
So, if you’ve waited longer than that and the oven is still cold, you likely have one of the following problems that need troubleshooting:
About this: All ovens use electricity, whether it’s a gas or electric Kenmore model. As you can imagine, an electric Kenmore oven needs that electricity to power its heating elements and other components.
However, a gas oven still needs electricity to power its components and the ignitor that helps the gas burn.
So, whether you have a gas or electric Kenmore model, you must ensure that the oven is plugged into the correct wall socket.
Besides that, it’s also crucial that the circuit breaker for that plug is also in the ON position to ensure that your oven has the power it needs to function correctly.
What’s wrong: The first reason your Kenmore oven isn’t heating is that there’s no power supply to the heating components or to the oven as a whole.
For example, a circuit breaker could have tripped, or the wall socket you use for the oven has malfunctioned.

Another possible issue is that there’s no electricity within the oven flowing to the heating element (in electric models) or the igniter (in gas models). That will also prevent your Kenmore oven from heating.
How to fix it: Fixing this problem will require you to ensure that your Kenmore oven is getting an incoming power supply. So, first, check the circuit breaker and wall socket to ensure that they’re both working.
Switch the circuit breaker on if necessary and get an electrician to fix the wall socket if it’s broken.
Next, the troubleshooting must focus on the oven’s internal wiring. The goal here is to ensure that the heating element or igniter are also receiving electricity.
A wiring issue will require a technician to troubleshoot and potentially replace the affected sections.
About this: The heat generation in a Kenmore gas oven relies on a crucial component known as the igniter. As the name suggests, this is the part that ignites the gas so it can burn and produce heat for the appliance.
The igniter is an electrically-powered component that’s placed next to the gas burner. When you turn on your oven, the igniter will receive a flow of electricity and glow brightly as it heats up.
That heat will keep the gas burner going for as long as you’re using the oven.
What’s wrong: The igniter heats up every time you use the oven and cools down when you turn it off. As a result, it experiences plenty of wear over time, causing it to gradually become weakened.
A weakened igniter will fail to start the gas burner, and that will prevent your Kenmore gas oven from heating up.
How to fix it: Gas oven igniters cannot be restored once they weaken. So, you’ll want to inspect it while the oven is turned on to confirm that it’s weakened. A weakened igniter won’t glow as brightly as it should, if at all.
Once the igniter cools down, you’ll have to disconnect its cable to remove it. Then, you can mount a new igniter in its place and reconnect its wiring accordingly.
About this: Kenmore ovens also rely on thermostats which regulate their internal temperature. Not only does a thermostat allow you to set a precise temperature, but it also ensures that the oven maintains that temperature consistently.
Once you set the thermostat to your desired temperature, it’ll ensure that the oven’s heating element turns on and off as needed to keep it at the right temperature without overheating.
What’s wrong: A Kenmore oven not heating suggests that the thermostat isn’t working correctly anymore. There are only two outcomes when that happens: the oven either overheats or doesn’t heat at all.
In this case, you’re experiencing an oven that doesn’t heat up even when you set your desired temperature.
How to fix it: Oven thermostats are another example of components that can be serviced or repaired. So, once yours stops working due to excess wear or a defect, the only solution is to replace it with another functioning thermostat.
Failed Main Control Board
About this: Your Kenmore oven’s functions are centralized at the main control board. That’s a printed circuit board that receives your settings and then controls the components to make them happen.
The main control board does that by sending electrical signals and power to the relevant components. When it comes to heating up your oven, that means sending power to the igniter or the heating elements.
What’s wrong: Unfortunately, the main control board can also suffer failures for many reasons. The board could have suffered an electrical fault, or excess moisture might be affecting it.
Whatever the cause, a failure in the main control board will stop your oven from working correctly. In this case, the failed board is not sending electricity to the oven’s heating components, like the igniter or the heating element.
How to fix it: You should only troubleshoot the main control board after ruling out all the other possibilities listed above.
Unfortunately, the damage or wear on a control board isn’t always visible. You might sometimes see burn marks, but that’s only if the board suffers an electrical fault.
Once you’re sure that the control board is the root cause of your oven problems, you’ll have to remove the one you have. Then, you must buy a new one to install into your Kenmore oven.
Buying a new control board can be a bit pricey. So, you must rule out the other causes before deciding to replace the main control board.
Frequently Asked Questions (FAQs)
Below are a few more questions and answers to help you troubleshoot your Kenmore oven not heating:
Do Burnt Wires Work?
No, burnt wires do not work correctly. Any burnt wires in your Kenmore oven will cause many different problems, including affecting its ability to heat up.
How Do I Clean The Igniter On My Kenmore Gas Oven?
You can clean the igniter in your Kenmore oven with a toothbrush. Use the brush to remove any debris and dirt from the gas oven.
What Causes Oven Igniter Failure?
Your Kenmore oven igniter will fail due to age and excess wear. When that happens, the igniter can’t take in enough electricity to generate the heat you need.
How Long Does It Take A Kenmore Gas Oven To Heat Up?
A Kenmore gas oven typically takes around 10 minutes to reach your set temperature. So, if it doesn’t heat up after that time, you should troubleshoot the oven for problems.
What Do I Do If My Oven Isn’t Hot Enough?
Partial heating is just as bad as an oven not heating at all. That’s because it can leave your dishes undercooked and jeopardize food safety. So, you must troubleshoot the oven yourself or with a technician to find out why it’s not getting hot enough.
