Air Fryer Not Heating Up Troubleshooting


  • Embracing the Air Frying Revolution: Air fryers have revolutionized home cooking, providing a healthier and more convenient way to enjoy fried foods. However, like any appliance, they are not immune to issues. One of the most common problems users face is the air fryer not heating up.

  • The Need for a Solution: Understanding the disappointment that comes when your air fryer fails to heat up, this guide is designed to help you diagnose and fix the most common issues, ensuring your culinary adventures can continue seamlessly.

1. Issue: A Faulty Outlet

  • The Prevalence of Outlet Issues: Though it’s not something that happens every day, air fryers can sometimes face issues due to faulty wall outlets. The signs of this problem can range from tripped breakers and short circuits to the air fryer refusing to power on altogether.

Solution to Faulty Outlet:

  • Testing and Switching Outlets: Start by unplugging your air fryer and allowing it to cool down. Once safe, try plugging it into a different outlet in a separate area of your house. This simple change can often solve the problem.

  • Utilizing a Multimeter: For those who have access to a multimeter and are comfortable using it, testing the original outlet for continuity can help confirm whether or not it is functioning properly.

2. Issue: A Damaged Power Cord

  • Understanding the Power Cord’s Vulnerability: The power cord may look sturdy on the outside, but inside it houses delicate cables that can be damaged through common mishandling practices like tangling or storing in cramped spaces.

Solution to Damaged Power Cord:

  • Initial Testing: First, try plugging the air fryer into a different outlet to see if the issue persists. This can help you determine whether the problem lies with the cord or elsewhere.

  • Considering Replacement: If the problem does seem to be with the power cord, replacements are widely available and typically affordable. Alternatively, if you have a spare cord that’s compatible, testing your air fryer with it can be a quick and cost-effective solution.

3. Issue: Air Fryer’s Tray Is Open

  • Safety Features and Their Implications: Modern air fryers come equipped with a variety of safety features, one of which is the prevention of operation if the tray or basket is not properly secured. This is a common issue that can occur after cleaning or disassembling the appliance, and it can lead to the air fryer refusing to heat up.

Solution to an Open Tray:

  • Ensuring Proper Assembly: To resolve this issue, ensure that all components of your air fryer are tightly and correctly in place. Pay special attention to the basket or tray, double-checking that it is securely closed and locked into position.

  • Reference to User Manual: If you’re unsure about how to properly assemble your air fryer or need assistance in identifying all the parts, refer to the user manual that came with your appliance. It should provide clear instructions and diagrams to guide you through the process.

4. Issue: A Broken Temperature Switch

  • The Role of the Temperature Switch: The temperature switch in an air fryer is a critical component for regulating the heat. If this switch is malfunctioning, it can disrupt the heating process, even when the dial is set to the highest temperature.

Solution to a Broken Temperature Switch:

  • Accessing and Testing the Switch: First, ensure that the appliance is unplugged and cool. Then, proceed to remove the exterior screws to access the internal components. Locate the temperature switch, usually situated behind the external temperature dial.

  • Using a Multimeter for Confirmation: Use a multimeter to test the switch for continuity. A lack of continuity indicates a need for replacement. Ensure you find a switch that is compatible with your air fryer model to guarantee proper functionality.

5. Issue: Blown Thermal Fuse

  • Protection Against Excessive Heat: The thermal fuse in your air fryer is a safety component designed to prevent potential fire hazards by blowing if the internal temperature of the appliance gets too high. While this feature is crucial for safety, it also means that a blown fuse will leave your air fryer non-operational.

Solution to Blown Thermal Fuse:

  • Locating and Inspecting the Fuse: After ensuring that your air fryer is unplugged and cool, open up the appliance to access its internal components. Locate the thermal fuse and inspect it visually for signs of damage, such as blackening or a broken filament.

  • Replacing the Thermal Fuse: If the fuse is indeed blown, it will need to be replaced. You can find suitable replacements at most hardware stores. Make sure to consult your air fryer’s manual to ensure you purchase the correct type of fuse for your specific model.

6. Issue: Faulty Heating Element

  • The Heart of the Heating Process: The heating element is crucial for converting electrical energy into heat, making it possible for your air fryer to cook your food. If this component fails, it can lead to inadequate heating or even complete loss of functionality.

Solution to Faulty Heating Element:

  • Testing the Element: Access the internal components of your air fryer once more, and locate the heating element. Use a multimeter to test its viability. A faulty heating element will show irregular readings and will need to be replaced.

  • Finding the Right Replacement: Replacing a heating element requires a bit of research to ensure compatibility with your air fryer’s make and model. Once you’ve found the right part, carefully install it following the manufacturer’s instructions or seek professional assistance if needed.

7. Issue: Restricted Airflow

  • The Importance of Proper Ventilation: Air fryers rely on the circulation of hot air to cook food evenly and efficiently. If there is any restriction in the airflow, it can lead to uneven cooking, reduced efficiency, and in some cases, the appliance failing to heat up.

Solution to Restricted Airflow:

  • Clearing Obstructions: Ensure that the air fryer’s vents are not blocked by any objects or accumulated debris. Regularly check and clean these areas to ensure unimpeded airflow.

  • Maintaining Internal Components: Sometimes, food particles or other debris can find their way inside the appliance and hinder the fan’s movement. Open up the air fryer and carefully clean around the fan and other internal components, taking care not to damage any parts.

In Conclusion:

  • A Solvable Problem: While encountering heating issues with your air fryer can indeed be frustrating, it’s important to remember that these problems are often solvable. The interconnected nature of the appliance’s components means that addressing one issue might resolve others, restoring functionality to your beloved kitchen helper.

  • Safety First: Always prioritize safety when attempting to troubleshoot or repair your air fryer. If you ever feel uncertain or overwhelmed by the process, don’t hesitate to reach out to a professional for help.

  • Happy Air Frying: We hope this comprehensive guide has been helpful in addressing the issues with your air fryer. With a bit of patience and careful troubleshooting, you should be back to enjoying crispy, delicious air-fried treats in no time. Happy air frying! Air Fryer Not Heating Up
