In the kitchen, nothing goes better with breakfast than a cup of coffee. You’ll be ready to jump out of bed with a full stomach and a fire in your belly.
It’s a ritual that dates back thousands of years when the Aztecs drank coffee by boiling the beans.
Since then, we’ve come to expect that the perfect cup of coffee will be a warm drink brewed with beans ground just right and served at just the right temperature.
But what if your grinder starts to get too hot to touch? Or, what if your grinder overheats and catches fire?
You might think that this is a question that only occurs in sci-fi movies, but that couldn’t be further from the truth.
These coffee grinders will overheat.
It doesn’t happen often, all you have to do is maintain your coffee grinder and avoid activities that will make it overheated.
If you learn how to work around your coffee grinder, you will be able to reduce the risk of overheating, it will cost you a bit of money, but it will solve your problem.
To determine why your coffee grinder overheats, we need to understand why this situation occurs in the first place. There are many reasons for this. Some of them are listed below:
It can fry the electrical components of your device if your coffee grinder is connected to an outlet that has a voltage higher than the recommended for your device.
If you don’t want to damage your coffee grinder you need to check the manual. It tells you all the things like at which voltage your coffee grinder works better.
You should look out for voltage regulators which you plug into outlets and sockets to control the output.
Because the coffee grinder works slower and has to put in more effort to grind whatever is in the device, when the voltage is lower than the recommended standard, it will make your coffee grinder overheated.
Don’t use your coffee grinder if the current is low, if you notice your grinder running slower than usual, make sure your circuit breaker isn’t faulty.
On for a Long Time
When you have a lot to grind, you may be tempted to do it all in one go, however, leaving your coffee grinder on for an extended period when you are processing will make it overheat.
When grinding coffee or any other substance in large quantities, the best way to do it is by grinding it in batches and allowing the grinder to rest for a bit.
Coffee will grind very slowly if you use dull blades for your coffee grinder. This will result in overheating of the coffee grinder.
The texture of your coffee grind will be affected by the dull blades you use.
You can easily sharpen your coffee grinder’s blades by doing it yourself or hiring a professional to do it.
If your blades are damaged beyond repair, you can purchase a replacement online or at a store.
As the coffee grinder gets older, the lubricant wears off, although most are equipped with permanent lubricated electrical motors.
If your coffee grinder begins to make a cranky noise when you’re grinding, that’s probably an indication that you need to lubricate the moving parts.
When you use a lubricant on your coffee grinder, make sure it doesn’t flow into your coffee while you’re grinding.
There is a finite amount of coffee beans you can stuff in the feeding tube of your coffee grinder, when you overpack the device, it can easily get clogged and make the coffee grinder overheat.
Don’t put too many coffee beans in your coffee grinder, take your time, put as much as you can fit, and leave some room. Feed the beans moderately as it is grinding.
Most of the time a battery cell is the only constant in devices that are overheating.
It can be the source of the overheating of a coffee grinder that is equipped with a battery so you can use it without plugging it in.
There are perks to using a coffee grinder, it is portable and compact, and you can use it whenever you like. If you travel a lot, it is highly recommended and you can also fly with it.
A faulty electric motor in your coffee grinder will cause it to get overheated.
We have all seen it before when electrical devices of any sort develop a fault, it begins to malfunction and will eventually short circuit.
It’s easy to fix the motor of a coffee grinder, it can be found in most stores. If you notice a malfunction, don’t use the coffee grinder as they are fire hazards.
When you have a low-quality grinder, it will start to overheat on its own as they are made with low-quality electrical components.
Coffee grinders are a bit pricey, but they are very sturdy and will be worth it over time.
The average coffee grinder can serve up to 3 years with regular use, the higher the quality the longer it lasts.
If it is warm in the kitchen or wherever you are using your coffee grinder, it will affect the temperature of your devices, which will cause them to become overheated.
Coffee grinders aren’t equipped with self-cooling fans which could help lower the temperature, so if you’re working in the kitchen, always ensure that it’s well ventilated.
It is your responsibility to provide proper airflow to lower the external temperature.
Hot Coffee Beans
Freshly ground coffee is the best for making any coffee beverage of your choice, the coffee beans are roasted to improve the flavor before grinding.
After you roast the coffee beans, you have to allow them to rest for as long as 24 hours for them to fully cook, as well as allow the flavor to fully develop.
Before grinding the coffee beans will raise the temperature of the coffee grinder, it will also produce a lot of oil, which will make it more difficult for the coffee grinder to process.
This becomes a slippery slope at the end of the process, you end up with a coffee grinder that is too hot.
Friction between the moving parts of the coffee grinder and also between the blades and the coffee beans will cause heat.
It doesn’t matter if it’s well lubricated or not, the gradual generation of heat will eventually get hotter until the device itself becomes overheated.
It’s a good idea to grind your coffee beans in small batches and give the device a bit of time to cool down.
Is It Possible to Grind Cocoa Beans in a Coffee Grinder?
It is easy to grind cocoa beans with a coffee grinder, they are usually dry and roasted to give them a depth of flavor that is similar to coffee beans, the shape and sizes are also pretty similar.

If you want to grind spices and grains in a coffee grinder, you should always clean your coffee grinder so that there isn’t any cross-contamination between the foods.
Best Way to Roast Coffee Beans
Roasting coffee beans over an open flame is the best way to do it. I think most of you are thinking over a grill, that is not how it works.
Toasting is done using a medium and unlike roasting where the food substance has to be in contact with the open flame, it is done using a medium.
The pan requires heat in this aspect, but it’s the medium. It is not necessary to put oil in the pan, just a dry pan, and your coffee beans.
Give room so you can toss them as they toast, and make sure you don’t overcrowd the pan. Coffee beans will burn fast if overcrowding is allowed.
Is It Possible For a Blender To Overheat?
Since it also has an electrical motor, the same condition also applies to the blender; any of the outlined complications mentioned above can affect it as well.
Purchasing a low-quality blender may change things a bit, they tend to overheat a lot and require a lot of downtime while using.
Is It Possible to Replace the Smaller Blades of a Coffee Grinder with a Larger One?
No, you are not able to. The coffee grinder’s blades are designed to fit the frame of the device, and trying to change it for a larger one makes no sense, I won’t fit at all.
If you don’t feel like your coffee grinder is powerful enough to get the work done quickly, then it’s time for you to get a new one.
You should get a larger and more powerful coffee grinder than the one you already have.

Is It Possible for a Burr Grinder To Overheat?
When a burr grinder is used it depends on two surfaces rubbing against one another to crush the coffee beans into a fine consistency, which causes the burr grinder to heat up.
There are pros and cons to owning a burr grinder as opposed to a blade grinder, but overheating is less in the burr grinder.
Difference Between a Burr and a Blade
- A burr depends on steel gears to grind the coffee beans, while the blade as the name implies uses sharp blades which move at high speeds to grind the coffee beans.
- Burr grinders are more expensive.
- Burr grinders are difficult to assemble and disassemble.
- Blade grinders are compact and easy to use.
It is possible to avoid overheating while grinding coffee beans or spices by taking the right measures and practicing proper maintenance of your coffee grinder.
