If this happens, there are a few possibilities behind it. Continue reading to find out why your nesco food dehydrator shuts off and what you can do to fix the problem.
Why Does My Nesco Food Dehydrator Shut Off?
There are a few different reasons your Nesco dehydrator might run too hot and keeps shutting off, so let’s look at some of the most common causes:
Faulty Overheat Protection
Overheat protection is a standard safety feature on electronic appliances, and food dehydrators are no exception. Nesco food dehydrators often shut off, and it’s likely due to this safety mechanism. The overheat protection feature kicks in when the dehydrator gets too hot and will cause the unit to shut down until it cools down.
This is generally not a problem if the dehydrator is used according to the manufacturer’s instructions. Still, it can become an issue if the unit is used for extended periods or in a location that is not well-ventilated.
Faulty or Blocked Air Circulating Fan
Your Nesco food dehydrator may shut off because the air circulating fan is faulty or blocked by food particles. The fan is responsible for circulating air through the unit; if it’s not functioning, the air can’t circulate properly.
This can cause the dehydrator to overheat. To check if the fan is the problem, look at it to see if it’s spinning. You’ll need to replace it if it’s not. To ensure proper air circulation, ensure nothing is blocking it if it is spinning.
A Deactivated or Faulty Heating Element
A Nesco food dehydrator that keeps shutting off might have a malfunctioning or deactivated heating element. The heating element is responsible for generating the heat that dries out the food, so the dehydrator will shut off if it’s not functioning properly.
You can check the heating element by looking for any signs of damage, such as burns or cracks. If you find any damage, you’ll need to replace the component. You can do this yourself if you’re handy with tools or take it to a qualified repair person.
Food Overload
A common problem with food dehydrators is that they will shut off due to food overload. Food overload occurs when so much food is in the dehydrator that the air can’t circulate properly. Dehydrators can overheat and shut down because of this.
To prevent this from happening, ensure you don’t overload your dehydrator. Start with a small amount of food, and add more if needed. Don’t try to dehydrate too much at once, or you may end up with a mess and a broken dehydrator.
Disconnected or Damaged Heater Wire
The heater wire is responsible for providing power to the heating element, so if it’s damaged, the dehydrator won’t be able to function properly. Sometimes, the damage may be repairable by soldering the wire back together.
But, if the damage is more extensive, you’ll need to replace the heating element. Fortunately, Nesco sells replacement parts, so you should be able to find what you need, and replacement wires are relatively inexpensive.
Blown Fuse
If your Nesco food dehydrator is constantly shutting off, it could be because the fuse has blown. The fuse is responsible for protecting the unit from electrical surges, and if it’s blown, there will be no power to the dehydrator.
Looking at the control panel, you can check to see if the fuse has blown. If the light is off, then the fuse has most likely blown. If it’s blown, you’ll need to replace it before the unit works again. You can find replacement fuses at most hardware stores.
Dirty or Clogged Vents
Dirty or clogged vents can cause the dehydrator to overheat and shut off. The vents allow air to circulate through the unit, and if they’re blocked, the unit will not function properly.
You can use a soft brush or air compressor to clean the vents to remove any debris blocking them. If the vents are significantly clogged, you may need to replace them.
As you can see, there are a couple of reasons why Nesco food dehydrators keep shutting off. If you’re having this problem, it’s best to troubleshoot it so you can get your dehydrator up and running again.
How Do I Know If My Nesco Food Dehydrator is Not Working?
There are a few tell-tale signs that your food dehydrator is not working correctly. One of the most obvious is if your food is not drying evenly. If certain areas are still moist while others are already hard and brittle, the air is not circulating correctly, and some parts of the food are not being exposed to enough heat.
Another sign that something is wrong is if your food takes significantly longer to dehydrate than usual. If you’ve been using the same setting for years and it’s taking twice as long to get the same results, then the heating element is no longer working as well as it used to.
The ideal temperature for drying food is between 130 and 140 °F. If the temperature inside your dehydrator does not reach this level, then your food will not dry properly. Also, if you notice that your food is beginning to spoil or develop mold, this is a sure sign that your dehydrator is malfunctioning.
How do I Fix My Nesco Dehydrator?
Nesco food dehydrators support a healthy lifestyle by allowing you to make your snacks at home with little prep time required. Dehydrators are also an excellent way to preserve foods for later. If you have a Nesco dehydrator, you may wonder how to fix it if it stops working correctly.
To fix this issue, follow these steps:
Step 01. Check to See if the Fan is Blocked
When troubleshooting your Nesco dehydrator, one of the first things you should check is whether or not the fan is blocked. A blocked fan can cause several problems, including uneven drying and poor air circulation.
Start by unplugging the dehydrator from the power outlet to check the fan. Then, remove the lid and look for any obstructions. If you see something blocking the fan, carefully remove it and discard it. Once the fan is clear, replace the lid and plug in the dehydrator.
Step 02. Clean the Ventilation Holes
If the dehydrator still keeps shutting off, the ventilation holes may become clogged with debris. Dehydrators can overheat in this situation and potentially start a fire. You will need a small brush and compressed air to clean the ventilation holes.
Remove any debris from the holes with the brush. Then, use the compressed air to blow out any remaining residue. Just aim the nozzle of the air can into the ventilation holes and give them a good blast. This will remove any debris that may have built up inside the dehydrator.
Step 03. Examine the Motor
When you are attempting to fix your Nesco dehydrator, you must take the time to examine the motor. In many cases, the problem with the dehydrator will be due to an issue with the motor. So, you will want to make sure you disconnect the power source before you begin any repairs.
Once the power source has been disconnected, you can remove the motor from the dehydrator. You need to inspect the motor for any signs of damage or wear. If the motor appears damaged, you must replace it before using the dehydrator again. Also, you should check to see if there is any buildup of dust on the motor.
Step 04. Reset or Replace the Thermal Fuse
If your Nesco dehydrator is not working properly, it may be due to a blown thermal fuse. In most cases, the thermal fuse can be easily reset or replaced. Here’s what you need to do:
- Disconnect the dehydrator from the power source.
- Remove the back panel of the dehydrator.
- Locate the thermal fuse on the back of the control panel.
- Check the continuity of the fuse with a multimeter. If there is no continuity, the fuse is blown and must be replaced.
- To replace the fuse, simply disconnect the old one and connect a new one in its place. Ensure the new fuse has the same rating as the old one.
- Once the new fuse is in place, reassemble the dehydrator and plug it in. The unit should now be working correctly.
By following these steps, you should be able to fix your Nesco dehydrator and get it working correctly again. But you should properly maintain your dehydrator to prevent future problems. To do this, clean it regularly and make sure the ventilation holes are clear.
Potential Solutions to Keep the Nesco Food Dehydrator Running Smoothly
Nesco food dehydrators are a great way to preserve foods. Even so, like all appliances, they can sometimes have problems. Here are some potential solutions to ensure that your Nesco food dehydrator runs smoothly:
- Make sure that the heating element is not obstructed. If something is blocking the heating element, it will not be able to dehydrate food properly.
- Check the temperature control setting. If the temperature is set too low, it will take longer for food to dehydrate. Conversely, if the temperature is set too high, it could damage the food or cause it to spoil.
- Clean the dehydrator regularly. Over time, particles can build up on the coils and other parts of the appliance. This can impede airflow and cause the dehydrator to work less efficiently.
- Store the dehydrator in a cool, dry place to prevent damage from moisture. As with any appliance, moisture can damage the dehydrator and cause it to rust or malfunction.
- Clean the trays and dehydrator tray supports with warm soapy water. Rinse and dry thoroughly before using again. This will prevent food from sticking to the stackable trays and make them easier to clean.
- Use only genuine Nesco replacement parts to maintain optimal performance. Otherwise, you risk damaging the dehydrator or voiding the warranty.
If the dehydrator is still not working correctly, there may be an issue with the power cord or heating element. If this is the case, it is best to consult a professional for repairs.
Can an Overheated Nesco Food Dehydrator Keep Shut Off?
According to the manufacturer, an overheated Nesco dehydrator will automatically shut off. It will automatically shut off if the dehydrator is turned on but not functioning properly. This is a safety feature to prevent the dehydrator from overheating & the reason is to avoid the food from overcooking or burning.
If the dehydrator does overheat, it will require time to cool down before it can be turned back on. It is essential to ensure that the dehydrator is placed in a well-ventilated area, so it does not overheat. Also, it is vital to clean the dehydrator regularly to prevent the build-up of food particles that can cause the unit to overheat.
Do Nesco Food Dehydrators Shut Off If They’re Overloaded?
Nesco food dehydrators are equipped with overload protection designed to trip if the dehydrator is overloaded. If the dehydrator is overloaded, the breaker will trip, and the unit will shut off.
This happens when there is a lot of food in the dehydrator, and the air can’t circulate properly. Thus, the dehydrator will overheat and shut off. You can avoid this by ensuring you don’t overload the dehydrator and keeping an eye on it while it’s running.
If the breakers trip off, you can reset the breaker by simply unplugging the unit and plugging it back in. Once the breaker has been reset, the unit will operate normally. If the dehydrator continues to trip the breaker, it is likely due to a faulty element or motor and should be replaced.
Can I Run a Nesco Food Dehydrator for Too Long Without Shutting Off?
While Nesco food dehydrators can be operated indefinitely without shutting down, it is not recommended. If you run a Nesco food dehydrator for too long without shutting it off, the food will dehydrate too much and may even disintegrate.
The length of time that you can run a dehydrator without shutting it off depends on the model, but most models can run for about eight to twelve hours without needing to be turned off.
If you are dehydrating foods requiring a longer drying time, such as beef jerky or fruit leather, you may need to turn the dehydrator off several times to ensure that the food dries evenly.
But, if you are only dehydrating foods with a short drying time, such as herbs or vegetables, you should be able to leave the dehydrator on for the entire drying time without any problems.
How Does the Nesco Dehydrator’s Thermal Fuse Work?
A thermal fuse is a safety feature found in many electrical devices, including the Nesco Dehydrator. The fuse is designed to open circuits against overheating, preventing device or fire damage.
Thermal fuses are triggered due to the heat generated by overcurrents, such as those caused by short circuits or component failures. Once the fuse is activated, it will not reset when the temperature drops, as a breaker would.
This ensures that the problem has been addressed and resolved before turning the device back on. Hence, if a dehydrator has been turned off for overheating, you should check for a blown thermal fuse before using it again. Otherwise, there is a risk of serious injury or damage to the appliance.
