Electric ranges combine an electric oven with a stove. While it’s common that one part works and the other doesn’t, it’s also possible for the oven and stove to stop working simultaneously. But why does that happen?
When your electric oven and stove stop working, there’s likely a problem with the incoming power supply, or the thermal fuse has blown. Besides that, you’ll want to troubleshoot the temperature sensor, control panel, and main control board.
This guide will walk you through the likely reasons your electric oven and stove aren’t working and what you can do to fix them.
Why Did My Electric Stove And Oven Stop Working?
When your electric stove and oven both stop working, there are a few likely causes you’ll want to troubleshoot. Firstly, check for incoming power supply problems and a blown thermal fuse. Then, troubleshoot the temperature sensor, control panel, and main control board.

Incoming Power Supply Problems
What it is: Electric ranges are made up of an electric stove and oven. The appliance’s power supply consists of two legs of voltage, each carrying half the power that’s needed. When both legs connect, it completes the circuit and allows the elements to generate heat.
Both voltage legs come from a single outlet where the appliance plugs into.
How it fails: When your electric stove, oven, or both fail to work, the first thing to troubleshoot is its incoming power supply. There’s a likelihood that the wall socket or plug is faulty. As a result, the stove and oven won’t receive the electricity the appliance needs to function correctly when that happens.
How to fix it: You can test your oven’s wall socket using a voltage meter set to volts AC. The readings will vary between 210 and 240 volts.
If you find that the socket isn’t supplying the correct voltage, the problem isn’t with your electric range. Instead, you must get a qualified electrician to troubleshoot the socket and your household’s electric supply.
Blown Thermal Fuse
What it is: The thermal fuse is a sacrificial component that protects your electric oven and stove from overheating. By doing that, the fuse prevents fires and further damage to the appliance and anything around it.

The thermal fuse is a part of the electrical circuit. It works very straightforwardly: if the temperature exceeds a certain level, the fuse will blow and cut the electrical circuit.
As a result, the oven and stove will not receive any electrical power and cannot continue overheating.
How it fails: A blown thermal fuse is only a symptom of a problem rather than the root cause itself. For example, excessive heat from the oven and stove will cause the thermal fuse to blow. That will cut the power and force the appliance to turn off, allowing it to cool down.

How to fix it: When a thermal fuse blows, you must replace it with a new one. Always begin any troubleshooting or repairs by disconnecting the appliance’s power source so you can work safely.
Then, you’ll have to remove the back panel of the electric range, which allows you to access most of its wiring and several of its components, like the thermal fuse.
When you’ve located the thermal fuse, disconnect its electrical wiring and remove it from the frame. You might have to unthread two or more screws that hold it in place.
Then, fit the new thermal fuse into its place. Next, secure it with the same mounting screws and attach the electrical wiring.
Remember: the blown thermal fuse is a symptom, not the root cause. So, you’ll want to also troubleshoot the rest of the oven and stove to find out why it was overheating in the first place. If not, the appliance will overheat again and destroy your new thermal fuse as well.
Problematic Temperature Sensor
What it is: The temperature sensor in your electric oven and stove continuously measures how hot the appliance is at any time. It will send that information to the main control board, which ensures that the actual temperatures match your set temperature.
When those two temperatures match, you’ll have much more precise control over your cooking.
How it fails: Temperature sensors can fail from being dirty or due to excess wear. Over an extended period, the sensor will get dirty with a coat of grease, food bits, and other substances. That will prevent the sensor from accurately measuring the temperature in the oven.
Besides that, the sensor expands and repeatedly contracts every time you use the appliance. That repetition will cause the sensor to wear out quickly, preventing it from measuring the temperature accurately.
In both cases, the sensor will mistakenly measure that the electric oven and stove are hotter than they actually are. As a result, it will prevent the appliance from heating up further.
How to fix it: Before purchasing a replacement, try to clean the existing temperature sensor while it’s cool. Take a damp piece of cloth and rub the sensor clean, making sure to remove any grease or food bits stuck to the device. If the stove still doesn’t work, then you’ll have to replace it with a new sensor.
The sensor is a metal rod sticking from the back of the oven. First, remove its mounting screws and pull it out slightly to expose its wiring. Then, disconnect the electrical connector to remove the sensor.
Next, reconnect the wiring to the new sensor and mount it in place securely.

Failed Control Panel
What it is: The control panel is where you communicate with the electric oven and stove. That’s where you turn the appliance on and adjust its various settings to ensure that your cooking experience is precise as how you need it to be.
When you press any of the control panel’s buttons, the panel will send signals to the main control board. Then, the control board will control the appliance’s components according to your chosen settings.
How it fails: The control panel on an electric oven and stove can fail from physical damage or an electrical fault.
For example, the buttons will eventually become unresponsive if they’ve been pressed or hit too hard.
However, it’s more likely that an electrical fault like a short circuit has made the control panel unresponsive. As a result, the oven and stove won’t work even when you press the buttons to turn them on.
How to fix it: Unfortunately, the control panel is not a part that you can repair. So, you must order a replacement and install it so your oven and stove can work correctly again.
The steps might differ slightly depending on your appliance brand and model. Typically, though, this replacement requires you to remove the rear panel of the control housing. That will allow you to remove the wire harnesses from the existing control panel and unmount it from the appliance’s frame.
Then, you can mount the new control panel in its place and reattach all the wire harnesses the same way as with the old one.
Faulty Main Control Board
What it is: The main control board is the part that carries out your instructions. The control panel will send signals to the main control board as you input your settings.
What it is: The main control board is the part that carries out your instructions. The control panel will send signals to the main control board as you input your settings.
Then, the board directs power and electrical signals to other components like the stove and oven heating elements. That allows you to cook your meals according to your set temperature and duration.
How it fails: The main control board and its components will fail if they experience a short circuit or a power surge. Excess heat from the oven and stove can also damage the board if it reaches the control board’s housing.
When the main control board becomes faulty, the electric oven and stove will malfunction or not work at all.
How to fix it: The only solution for a faulty main control board is to replace it with a new one. Unfortunately, it’s not practical to repair only the affected components on the board. So, purchase a new board and install it in your electric oven and stove.
Refer to your user manual to locate the board’s housing. Then, remove the wires connected to the existing board and free the board.
Then, install the new board and reconnect the wires the same way as the board you’re replacing.

Frequently Asked Questions (FAQs)
Here are some other questions you might have about your electric oven and stove:
Is There A Reset Button On An Electric Oven?
No, electric ovens do not have a reset button as a standard feature. However, the manufacturer has likely programmed a reset feature into its control panel.
So, it’s best to refer to the user manual for your model to know which buttons will reset the appliance.
How Do I Know If My Oven Fuse Is Blown?
The first sign your oven fuse has blown is that the control panel works, but the appliance won’t heat up. However, the only way to confirm it is by checking for electrical continuity using a multimeter. When there’s no continuity, that means the fuse has blown.
