The appliance only has a fault, and don’t forget, every appliance will get to this phase one day. So, identify and fix the problem. Below, we’ll look at the various issues the Cuisinart air fryer toaster oven may have that can prevent it from working properly.

After reading, you should be able to identify and tackle some of these problems head-on. 

Here’s a quick summary of the common problems the Cuisinart air fryer toaster oven may have. 

  • Oven power failure
  • Oven has a faulty switch
  • Toaster oven has faulty lights
  • Oven develops a smoke problem
  • Possible sparking inside the oven
  • Oven suddenly stops functioning
  • Oven powers up but refuses to heat up
  • Odorous food problem

Now, let’s look into each problem one after the other and share tips on what you can do in each instance. 

1: Cuisinart power disruption problem: 

Electrical appliances require electricity to function. The Cuisinart air toaster oven is not battery-powered. You have to connect it to a power supply to use it. 

Unfortunately, an unstable power supply can be Cuisinart’s undoing. It can cause severe problems within the appliance. 

Let’s say, for instance, a sudden power outage occurs in your area. What do you think could happen to your toaster oven? Of course, the disruption can cause power failure. 

The sudden power outage can damage critical components in your Cuisinart air fryer toaster oven. It can also destroy some of the wires.

This issue is common when a power outage suddenly occurs when the appliance is in use. Additionally, when the components, including wires becomes faulty, keep in mind that the appliance won’t turn on again unless you fix the problem. 

Power disruption that leads to power failure is a common problem in Cuisinart air fryer toaster oven. 

Now, is this problem reparable? Yes, it is. 

How to fix this problem: 

You have to check the following components to ascertain where the problem lies. 

  • Thermal fuse:

If your Cuisinart toaster oven has a problem, the thermal fuse could be the culprit. This fuse is crucial to the normal operations of the appliance. It helps to protect it against overheating, including other functions that may affect the appliance negatively. 

Now, how do you know the fuse is bad? You can detect it by using a continuity tester to test it. If the tester show the fuse has blown, endeavor to fix a new one. 

It is essential to clean the fuse from time to time. Don’t forget the thermal fuse help protect the appliance. Another thing you should know is that this component isn’t expensive. 

  • Solenoid:

The solenoid is another vital component of the toaster oven to check whenever it isn’t working, as it should. There’s a chance the power disruption has affected the solenoid.

The thing is the solenoid helps in controlling the flow of electricity to the toaster oven heating element. So, your toaster oven will produce the heat required to make your foods crispy when the solenoid is in order. 

Power disruption, caused by a sudden power outage, can affect your solenoid. It can either make the solenoid faulty or wholly damaged. 

Your toaster oven will generate a small amount of heat when the solenoid is faulty, but it won’t be enough to make your food crispy. 

On the other hand, if the solenoid has been damaged completely, your Cuisinart’s cooking chamber won’t heat up. 

You can fix this problem by replacing the solenoid. You can do it yourself if you have the tools and technical know-how. But if you can’t, please find a reputable technician to fix it. 

The solenoid comes in diverse ratings and sizes, including other details. Fixing the wrong one can harm your appliance, and you wouldn’t want to walk that path, given Cuisinart’s price point. 

  • Damaged electric socket:

Is it possible for the wall socket connecting your oven to develop a fault? The simple answer is yes. Ovens use an incredible amount of electrical power to generate heat. 

So, before you conclude that your oven has a power disruption problem, check the electricity socket. 

Before taking the next step, you must determine if the electric socket is faulty. How do you identify if the socket has a fault? Use a tester to test and see if it supplies the electricity. Another way to determine this is to connect your Cuisinart toaster oven to another wall socket. 

If the electricity socket is the culprit, you have to replace it. Firstly, it would make sense to cut off the power supply from your home before you begin. The reason is to avoid getting electrocuted in the process. 

Now, fix the new wall socket the same way you removed the old and damaged one. 

A Handy Tip: The air fryer toaster oven uses 10 amps. So, ensure you’re using an outlet that can withstand the appliance’s power demands. Furthermore, avoid plugging your toaster oven with appliances like the microwave in the same outlet. 

No one is saying you can’t plug a microwave in an outlet where you have your air fryer toaster oven plugged in. You can do so, but you can’t use them simultaneously. It is not advisable to do so. 

  • Worn-out cable: 

Another thing to check is the cable of the oven. Check if the insulation is exposed and use masking tape if you find any exposed portion. 

Please, check the cable thoroughly to see if there is any broken part. Don’t forget that a short circuit is possible if the wire is broken somewhere. 

A short circuit can damage the appliance and may get you electrocuted. So, fix the problem while there’s still time to do so. 

A Handy Tip: If your Cuisinart air fryer toaster oven with a power disruption problem has a display screen, error codes will display on the appliance’s screen. The code will guide you on how to fix this problem.   

2: Cuisinart faulty power switch problem:

Do you know your oven’s power switch can also develop a fault? If the main switch is faulty, you can still power the oven with it. 

However, if the switch is damaged completely, the appliance won’t power up when you try to turn it on. 

Please, note that the oven’s main switch can develop a fault over time, though you can fix this problem.

However, don’t try to repair the faulty switch. Once you notice the switch is defective, change it immediately. Please don’t wait for it to be wholly damaged before you act. 

You can change the main switch yourself if you have technical knowledge. But if you don’t have the knowledge and tool, please let a technician fix it. 

A Handy Tip: Dirt and dust accumulate on the main switch over time, and this can cause it to develop a fault quicker than anticipated. 

So, clean your oven’s switch from time to time. Make it a habit to clean the entire appliance occasionally. 

3: Cuisinart faulty light problem:

A fault or damaged internal light is one of the problems toaster ovens experience. A faulty light won’t stop the appliance from working but would affect how you use it.

The internal light helps users to monitor whatever they’re cooking in the appliance. With this light on, the chances of you overcooking or undercooking your foods are slim. 

This internal light can develop a fault at any time. The light can become dim or wholly damaged. 

How to fix this problem:

The first step is to identify the root cause of the problem. Is it that the bulb itself has blown? Is the fault from the motherboard? Again, is the appliance’s door not latching correctly, or is the air fryer basket improperly positioned?

Find out the actual cause of the light problem your appliance has. 

If the bulb has blown, or it is too faint then you should quickly get a replacement and fix it yourself. However, let a trained technician handle the repair if the issue is from the motherboard.

This is because when not correctly handled, the motherboard may suffer further damages, increasing the amount you may have to pay for repairs. 

However, if the door isn’t shutting properly, check if something is preventing it from latching properly. Lastly, remember that an improperly positioned air fryer basket can prevent the light from coming on. 

So, check if the air fryer basket is positioned correctly. If it’s not, please do the right thing. Position it before you proceed. 

4: Cuisinart develops a smoke problem:

Is your Cuisinart air fryer smoking excessively? If yes, then do the right thing immediately. Unplug the appliance from the wall outlet and wait for the smoke to disappear. 

Smoke alone is a health hazard. And above all, it indicates that something isn’t right with your appliance. 

Before you take further steps to fix this problem, here is what you need to understand. Different colors of smoke may come out of the appliance. You’ll find black, white, or blue.

Each color of smoke means something. Let’s explain them briefly. 

The black smoke:  If you discover a black-colored cloud, you’re dealing with burnt fatty foods. You could even smell the smoke if you have a super sensitive nose. 

The back smoke usually pops up when using high heat in the air fryer to burn the oil. 

Note that Cuisinart is against cooking highly fatty foods in its air fryers. When you do, your entire kitchen will be covered with black smoke, which isn’t good for your health. 

The white smoke:  If you discover white smoke from your oven, it indicates steam collecting in the air. 

You’ll notice this smoke problem when you cook high-fat or moist foods in the oven. The problem could be a result of the user’s carelessness. 

The Cuisinart air fryer is meant to cook foods without you adding water or oil. When you do, your entire kitchen will be covered with white smoke before you know it.  

So, follow the guidelines when using any appliance. Don’t try to make your own rules or neglect the manufacturer’s instructions

Finally, if you find white smoke coming out of your appliance, unplug it immediately, then try removing the water or oil that’s causing the problem.

However, if the problem persists after cleaning the Cuisinart thoroughly, make plans to take the appliance to a reliable repair shop. 

The blue smoke: Blue smoke isn’t that common, but it can happen anyway. When you find this color smoke coming out of your Cuisinart air fryer, know that all isn’t well with the appliance. 

The blue smoke indicates that your appliance could be having an electrical fault. And while malfunctioning, your Cuisinart air fryer could be overheating and melting plastic materials on its way. 

If you notice the blue-colored smoke emanating from your appliance, quickly unplug it from the wall outlet. Otherwise, it may overheat and cause severe damage to the components inside the appliance. 

5: Sparking problem inside the oven:


Do you see sparks in the cooking chamber whenever you turn it on or try using the appliance? If yes, then something isn’t right with the insulation.  

The oven’s insulation may break down following constant usage of the appliance. The breakdown may also cause the wires inside the appliance to touch the stove, a danger you must avoid. 

How to fix this problem:

If you’re seeing sparks in your oven’s cooking chamber, please don’t continue using the appliance. The breakdown of the insulation could have caused the sparks. Wrong wiring is also a culprit. 

Fixing this problem might look easier on the outside, but this is something you should never undertake. Why? Repairing the appliance and making a mistake can lead to fire hazards or electrocution.

So, contact a well-trained technician you can trust to fix your faulty oven. Again, please unplug the oven and inform everyone at home not to use the appliance until it’s fixed.

6: Oven suddenly stops functioning:

If your Cuisinart oven suddenly stops working, do not panic. Several factors could be responsible for this problem. Let’s discuss each of them, including what you can do to fix the problem. 

Faulty thermostat:  If your oven suddenly stops working, the thermostat could be the culprit. There’s a chance that the thermostat, which regulates temperature, has stopped working, forcing the appliance to overheat.

The heat will rise to a point where the oven’s safety thermostat will become active and shut down. You can fix this problem by replacing the faulty thermostat. 

Ventilation problem: Ventilation problem can also cause your oven to stop working, as it should. A problem with the fan or even the motor responsible for the fan’s rotation can give rise to a ventilation problem.

When this happens, note that there’s a possible of blockage of the airflow, causing the appliance to overheat. To fix this problem, all you have to do is replace the ventilator. 

Wiring problem: If your oven suddenly shuts down, the wiring in the different components of the appliance could be the culprit. If this is the case, please don’t fix the problem yourself. Contact a well-trained and licensed technician to fix it. 

Blown fuse: If your oven suddenly stops working, don’t panic. Why? The reason could be a minor fault, such as a burnt fuse. The fuse is located in the appliance’s plug head and helps protect it. The fuse usually takes a hit when there’s a power surge. 

So, if your oven stops working, check the fuse. If the one on the plug head has blown, get a new one. 

Damage control board or faulty switch problem: These two problems can cause your oven to shut down. But you can fix them with the help of a technician. 

7: Oven powers up but refuses to heat up:

This is how the toaster oven works. When turned on, the solenoid transfers the electrical current to the heating element. The electrical current then charges the heating element, causing it to produce heat energy. 

So, if there’s an issue with your solenoid, heating element, and other components that must be in good shape for the oven to generate enough heat, the appliance won’t work as it should.

In this case, your oven will only power up but won’t heat up. It is better not to have a toaster oven than one that can’t generate enough heat. 

How to fix the problem:

The first step is to identify the faulty component that’s making it impossible for the oven to generate enough heat. So, here are the possible culprits if your oven turns on but doesn’t generate much heat. 

Problem with the Heating element: You can identify this problem via a simple test. Turn on the oven, open the door and place your hand inside.

If it doesn’t generate enough heat that makes your hand uncomfortable, the heating element could be having some problems. You can fix this problem by replacing the damaged or faulty heating element. 

Problem with the solenoid: You can also check the solenoid to see if it has a problem. Don’t forget that a faulty solenoid will make it impossible for your oven to generate enough heat. 

Blown fuse: This component can also make your oven stop working. So check it properly and replace it if damaged. 

Problem with the control board: This board is crucial to your oven’s operation. It contains the switches used to control the appliance’s temperature and timer. So, if your control board starts malfunctioning, the oven won’t be able to generate enough heat. 

Faulty thermostat:  With a faulty thermostat, your oven may turn on when you hit the power switch, but it won’t generate enough heat. 

8: Odorous food problem:

This problem is common when the air fryer overheats. It will produce a plastic smell, which can engulf the food you’re cooking and even change its taste slightly. 

Another thing that can cause this problem is when you don’t clean up the appliance properly. So, when you try cooking another food, the food particles from the last food prepared in the appliance will engulf your food. 

How to fix this problem:

If the problem is caused by overheating, unplug the appliance and examine it for any possible fault. You can contact a licensed technician to check the appliance if the problem persists. 

However, if the problem is because of previous food particles left in the oven, try cleaning the appliance to fix this problem.
