Air fryers are essentially miniature countertop convection ovens. They work by using a fan to move heat around the food. This function is similar to the convection feature in a full-sized oven or a large toaster oven.

However, air fryers are not as hot as your oven. None of the air fryers available on sale can exceed 400 degrees Fahrenheit.

For instance, the COSORI Air Fryer. The Cosori has received rave reviews and is reasonably priced. It is best for someone who wants to try air frying without investing much money in something they’re not sure about.

Why Does My Air Fryer Set Off the Smoke Alarm

You’ve probably heard about all the benefits of air fryers if you own one or are considering buying one. However, many people are curious as to whether air fryers trigger smoke alarms.

The smoke alarm will most likely go off if there’s smoke from your air fryer. The smoke is usually due to food or oil splattering on the heating element. If this occurs, turn off the air fryer and carefully wipe the bottom of the machine with a paper towel. Attempt to remove all of the excess grease.

Avoid cooking super-fatty foods in the air fryer, such as bacon. If you cook fatty foods, keep in mind that smoking may be a byproduct of the process. Smoking is likely to occur when high-fat foods are cooked at high temperatures. Place bread at the bottom of the air fryer to see if it helps reduce some of the smoking. 

The majority of it, however, will be due to fat splattering on the heating elements. You can’t avoid this unless you cook high-fat foods on the stovetop or in a conventional oven. However, it should be no surprise that stovetop-cooked bacon produces more grease splatter and smoking than air fryer-cooked bacon.

Inspect the heating elements if you still detect smoke after cleaning the air fryer and not using it for cooking high-fat foods. Food particles may have become stuck to the heating elements and are now burning.

Allow the air fryer to cool completely before wiping down the heating element to remove old grease and food particles. Finally, make sure that the temperature is set correctly. If you cook at too high a temperature, you risk burning your food and producing smoke.

Do Air Fryers Catch on Fire?

Do Air Fryers Catch on Fire

Due to their popularity, air fryers receive a lot of reviews, some of which are unfavorable. There are risks and safety precautions you may need to think about with this equipment, just like with other electrical items. But do air fryers actually catch fire?

It is unlikely for an air fryer to catch on fire despite people’s belief that it is prone to causing fire hazards. But, it is not impossible. User error, dirty machines, and even faulty machines can all cause a fire. For example, it may catch fire if you do not follow the manufacturer’s instructions and are not cautious.

As a result, it is not limited to air fryers and can occur with other household appliances. In addition, an air fryer catching fire is a rare occurrence. A deep fryer is an alternative to an air fryer. An air fryer sounds far more dangerous than a large vat of hot oil on your countertop or stovetop.

However, air fryers are far safer than traditional deep fryers. Have you ever made frozen french fries in your deep fryer? If you have, you may be aware that when you place frozen fries in your deep fryer, they splatter all over the place. I know this because when I deep fry french fries, I always dump and run! With my air fryer, however, I simply place some fries in the basket, set the temperature, and wait. Simple as that.

Do not place your air fryer directly on your stovetop or countertop. When used on a stovetop, it can cause the unit to melt and even catch fire.

These Amazon Supmat XL Extra Large Silicone Mats come in a set of two and would be ideal. They are also multifunctional. You can line your oven with one and use the other to protect your countertops!

Best Air Fryers

  1. DASH Compact Air Fryer

The Dash Compact is an excellent air fryer for people who only cook for themselves or for those who are new to air frying and want to give it a try. With a capacity of 1.7 liters, it can quickly cook one portion of food. Its small footprint means it takes up less space on your counter, and the compact basket makes cleaning easier. 

This model has a dial timer, which makes it difficult to program to the minute. A dial also controls the temperature, and there aren’t many options, but I found the Dash a good choice because I air fry most foods at the maximum 400°F temperature. It comes in various vibrant colors, unlike most air fryers on the market. The aqua color variant is a personal favorite.


  • Available in varieties of colors
  • It does not take up as much counter space as full-size models


  • Homemade fries did not cook uniformly.


Failure to do the one thing your air fryer was designed to do can defeat the purpose of owning it and leave you extremely frustrated. As you’ve discovered, this problem could be caused by various factors. Because the components in your air fryer are interdependent, a single failure can create a chain reaction.

Safety should always be your priority, so if you have any doubts, do not hesitate to contact a technician.
