Why Is My Air Fryer Not Heating Up?

Although air fryers are known for their convenience, popularity, and user-friendliness, they are still a mechanical device with components that can malfunction, requiring occasional troubleshooting.

Although certain brands may encounter more issues than others, most problems can be resolved by referring to the user manual or verifying the appliance during operation.

Typically, the heating element is the culprit when air fryers fail to heat up, but there are other factors that can contribute to this issue, such as:

  • Failure to adjust the temperature could be the reason why your air fryer is not heating up.
  • Failure to set the cooking time can cause your air fryer not to heat up properly.
  • The set temperature is too low.
  • If the door is obstructed or not securely shut, it may cause the air fryer to not heat up.
  • The heating element may not be receiving power due to a connection issue with the power source.

This article contains information that may be specific to your air fryer as the author has researched multiple brands.

Can You Overheat an Air Fryer?

Although air fryers may appear straightforward to operate, it can be quite effortless to commit errors during usage if you lack knowledge of its functioning or fail to follow the user manual.

Not catching these errors in time can lead to overheating or even fire hazards with your air fryer. To prevent this, it is important to avoid the following actions.

Overfilling Your Air Fryer With Food.

It is important to avoid overfilling the air fryer basket with food. If you exceed the maximum fill line, it can reduce the space between the heater and fan, potentially leading to a fire or causing your appliance to heat up too quickly. To prevent this, make sure to not stack food too high in the basket.

Filling the Basket with Oil/Other Liquids. 

One common error that can lead to air fryer malfunction is adding oil to the basket separately from the food ingredients, which may result in overheating or even fire hazards.

To ensure that your Air Fryer is heating up correctly, begin by combining the recipe’s suggested amount of oil with your food ingredients. Then, place the mixture into the air fryer basket. Avoid using any other type of liquid in the basket.

Placing Items on Top of the Air Fryer.

Although it may seem unlikely, if you put objects on top of your air fryer, it can overheat due to the blocked inlet air intake that restricts airflow into the unit, resulting in insufficient air circulation and overheating.

Blocking the Air Outlet.

Just like the previous point, obstructing the air outlet can result in the retention of heated air inside the air fryer, leading to overheating.

It is important to ensure that there is a minimum of five inches of space above, behind, and on both sides of your air fryer to avoid obstructing the air outlet.

Using the Air Fryer for an Extended Period of Time.

Typically, air fryers designed for home use lack the commercial-grade quality, durability, and performance necessary to endure prolonged usage.

Extended use of an air fryer for more than 60-120 minutes can lead to overheating of its internal components, which can be avoided by preheating the device before placing food in it.

What Else Can Cause My Air Fryer To Stop Working?

Although overheating can be the reason for your air fryer to turn off or cease functioning altogether, there are several other problems that could be responsible.

Check Your Power Supply.

Many times, air fryers may turn on but fail to function properly due to faulty electrical wiring, resulting in improper heating.

To address the issue of an air fryer not heating up, it is important to ensure that it is correctly plugged in and has sufficient ventilation, verify that the timer is functioning correctly, and check for any problems with the circuit breaker.
