Air fryers are among the most popular cooking tools in UK households. Their high demand is not only because they save energy and electricity, but also because they can make soft, crispy, and delicious food in a short time. Dual air fryers, in particular, are more convenient and efficient. However, even the best air fryers can malfunction if used improperly. In our previous blog, HYSapientia explored the issue of air fryers not running and provided detailed solutions. Today, we will discuss one of the most common problems with air fryers—overheating, which poses a potential fire hazard.


Causes of Air Fryer Overheating

Prolonged Continuous Use

Air fryers are designed for short, efficient cooking. However, if used continuously for long periods, the internal components can overwork and struggle to dissipate heat, leading to overheating. Every air fryer has its design limits; exceeding these limits causes the internal temperature to rise continuously, overloading the heating elements. If you notice the air fryer casing getting excessively hot or smell burning odors during use, this might indicate prolonged use. It is recommended to allow the device to cool down after each use. This not only extends the lifespan of the air fryer but also ensures cooking safety.


Poor Ventilation

Air fryers require good air circulation to dissipate heat effectively. Placing them in a confined or enclosed space where the ventilation ports are blocked can cause the temperature to rise quickly. This not only affects cooking performance but can also damage the appliance. When using an air fryer, place it on an open countertop, ensuring no obstructions to the ventilation and heat dissipation ports. Regularly clean the ventilation ports to prevent grease and food residue from blocking them, ensuring the device can dissipate heat normally.


Malfunction of the Air Fryer

Internal malfunctions, such as a faulty thermostat or heating element, can also lead to overheating. The thermostat is crucial for controlling the temperature of the air fryer. If it fails, the device will not regulate the temperature correctly, continuing to heat until it overheats. A malfunctioning heating element can cause localized overheating, potentially damaging other electrical components. If you notice any abnormalities in your air fryer, stop using it immediately and contact a professional repair technician to inspect it, preventing further damage and safety hazards.


Overfilling the Air Fryer

The internal space of an air fryer is limited. Overfilling it with food not only hinders air circulation and even heating but can also cause the appliance to overheat. Every air fryer has a maximum filling capacity. Exceeding this limit restricts air circulation, leading to uneven heat distribution and localized overheating. To ensure even cooking and safe operation, avoid exceeding the recommended capacity, especially with large items requiring longer cooking times.


Grease Accumulation

If grease produced during cooking is not cleaned promptly, it can accumulate inside the air fryer or on the heating element, leading to overheating and even fire hazards. Grease impedes the air fryer's ability to dissipate heat and can ignite at high temperatures, creating a safety risk. Clean the air fryer thoroughly after each use, including the basket, heating element, and ventilation ports, to prevent grease buildup. Use warm water and mild detergent for cleaning, ensuring the fryer is thoroughly cleaned before the next use.


Consequences of Air Fryer Overheating

Overcooked Food

Overheating can cause food to be overcooked, becoming too dry or burnt, affecting the taste and potentially producing harmful substances. When the air fryer temperature is too high, the surface of the food dehydrates quickly, preventing even evaporation of internal moisture, resulting in burnt exteriors and undercooked interiors. This not only impacts the texture and flavor but can also generate harmful substances like acrylamide, posing health risks. Therefore, maintaining proper temperature control is crucial, especially when cooking sensitive ingredients.

Shortened Air Fryer Lifespan

Continuous overheating can damage internal components such as the heating element and fan, shortening the appliance's lifespan and increasing repair costs. Overheating can deform plastic parts and burn out circuit boards, affecting normal usage. To avoid damage, users should monitor usage frequency and duration, preventing prolonged high-load operation. Regular inspections and maintenance, replacing aging or damaged parts timely, are essential.

Fire Hazard

Overheating can cause a fire, especially if there are flammable materials nearby. The high internal temperature of an air fryer can ignite external flammable items, leading to serious fire accidents. Keep air fryers away from flammable items like paper towels, cloths, and other combustibles during use, and place the appliance on a heat-resistant surface. Regularly clean and inspect the device to prevent grease and food residue buildup, which is crucial for fire prevention.


Burn Risk

The exterior temperature of an overheating air fryer can become very high, posing a burn risk, especially for households with children. The exterior temperature can exceed 60°C during operation. Be cautious to avoid direct contact with high-temperature surfaces. To reduce burn risk, consider using heat barriers around the appliance to prevent accidental touches by children. Additionally, use heat-resistant gloves and tools for operation.


Energy Waste

Overheating increases power consumption, leading to unnecessary energy waste and higher electricity bills. Prolonged high-temperature operation not only shortens the air fryer's lifespan but also significantly increases energy consumption, negatively impacting the environment. To save energy and reduce costs, schedule cooking times and temperatures reasonably, avoiding unnecessary high-temperature operations. Opt for energy-efficient air fryer models for better performance.
