1. Air Fryer Won't Turn On
Check the Power Source Before anything else, verify that your air fryer is receiving power. It might sound basic, but sometimes the outlet or power strip is the culprit. Try plugging the air fryer into a different outlet or test the outlet with another device to ensure it’s working.
Inspect the Power Cord and Plug Examine the power cord for any visible damage such as cuts, frays, or bent prongs. A damaged cord can prevent power flow and create safety hazards. If the cord looks worn or broken, discontinue use and contact the manufacturer or a professional for repair.
Reset the Air Fryer Many models have a built-in reset feature or thermal fuse to protect against electrical faults or overheating. Check your user manual for instructions on how to reset your specific model. Sometimes, a simple reset is all it takes to bring your air fryer back to life.

2. Air Fryer Not Heating or Heating Slowly
Temperature Setting Issues Always double-check that you’ve selected the correct temperature. Some digital panels can be tricky or reset accidentally. Most air fryers operate best between 80°C to 200°C (176°F to 392°F). If the temperature is set too low, cooking will be slow or ineffective.
Overloaded Basket Overfilling the basket restricts airflow, which is essential for the air fryer’s rapid cooking process. This causes uneven heat distribution and slower cooking times. Follow your air fryer’s recommended capacity guidelines to ensure optimal airflow.
Faulty Heating Element If your air fryer powers on but fails to heat properly, the heating element may be damaged or malfunctioning. This is a more serious issue that usually requires professional repair or replacement. For reliable models, consider checking [our air fryer reviews](/reviews) before purchasing.

3. Food Not Cooking Evenly
Basket Overcrowding One of the most common causes of uneven cooking is overcrowding the basket. When food items are piled on top of each other, hot air cannot circulate evenly, leaving some pieces undercooked while others may burn.
Incorrect Temperature or Timing Different foods require different temperatures and cook times. Using generic settings or following recipes not designed for air fryers can result in uneven or poor cooking. Refer to specific air fryer recipes or adjust based on your experience.
Basket or Tray Position Ensure the basket or tray is properly aligned and fully inserted. A misaligned basket can block airflow or cause heat to distribute unevenly, affecting cooking results.

4. Food is Soggy Instead of Crispy
Insufficient Preheating Preheating your air fryer for 3-5 minutes before adding food is crucial. This step ensures that the air fryer reaches the set temperature and that hot air is circulating, leading to crispy exteriors.
Excess Moisture in Food Foods that are wet or heavily marinated tend to steam rather than crisp. Always pat dry meat, vegetables, or frozen items before cooking to reduce moisture and enhance crispiness.
Low Temperature Settings Cooking at temperatures below 180°C (356°F) may not trigger the Maillard reaction, the chemical process responsible for browning and crisp texture. Increase the temperature to achieve that golden finish.
---
5. Smoke Coming from the Air Fryer
Excess Oil or Grease Using too much oil or cooking fatty foods like bacon can cause grease to drip onto the heating element, producing smoke. To avoid this, use oils sparingly and clean the drip tray regularly.
Food Residue Leftover crumbs, burnt bits, and grease buildup can ignite and cause smoke. Clean your air fryer thoroughly after every use, paying special attention to the basket, tray, and heating element area.
Cooking at Too High Temperatures Cooking delicate or thin foods at very high temperatures (above 200°C / 392°F) can cause burning and smoke. Adjust temperature and cooking time accordingly.
---
6. Air Fryer Basket Won't Slide In or Out Smoothly
Obstructions in the Basket Slot Check for any food debris, crumbs, or foreign objects blocking the basket slot. Even small bits can cause the basket to stick or jam.
Warped Basket or Tray High heat exposure over time can warp plastic or metal parts, preventing smooth insertion or removal. If warped, you may need to replace the basket or tray.
Incorrect Basket Placement Make sure you’re inserting the basket correctly according to your model’s instructions. Forcing it in the wrong way can damage the appliance or basket.
---
7. Air Fryer Makes Loud or Unusual Noises
Fan Obstruction The fan is responsible for circulating hot air and can produce noise if blocked by food debris or a loose part. Remove and clean the basket, then inspect the fan area carefully.
Loose Components Rattling or vibrating noises can result from loose screws or panels. If accessible, tighten screws or consult a technician for assistance.
Normal Operating Sounds Some noise is normal due to the fan and heating element working. If the sound is louder or different than usual, compare with sounds from [our air fryer reviews](/reviews) to check for abnormalities.
---
8. Display or Control Panel Not Responding
Power Reset Unplug the air fryer for 5-10 minutes to reset the electronics, then plug it back in. This often resolves minor glitches.
Touchscreen Calibration Touchscreens may need recalibration or cleaning. Wipe the control panel gently with a soft, damp cloth and refer to your manual for recalibration steps.
Firmware Glitch Some smart air fryers may require firmware updates. Visit the manufacturer’s website for available updates or troubleshooting guides.

Common Mistakes to Avoid
- Overfilling the Basket – Crowding restricts airflow, leading to uneven cooking or undercooked food.
- Ignoring Preheating – Skipping preheat lengthens cooking times and results in soggy textures.
- Using Cooking Spray Inside the Basket – Cooking sprays can leave sticky residues that damage the non-stick coating. Instead, brush oil lightly.
- Not Cleaning Regularly – Built-up food residue causes smoke, unpleasant odours, and poor cooking performance.
- Using Metal Utensils on Non-Stick Surfaces – Metal tools scratch and degrade the basket’s coating, shortening appliance life. Use silicone or wooden utensils.
- Cooking Frozen Food Without Adjusting Time – Frozen foods typically require longer cooking times; failing to adjust results in cold or raw centres.

Pro Tips for Effective Air Fryer Use
- Shake or Flip Foods Halfway Through Cooking – This promotes even browning and crispiness, especially for fries, nuggets, or vegetables.
- Use a Light Brush of Oil Instead of Sprays – Brushing ensures an even coating without sticky buildup and enhances crispness.
- Avoid Stacking or Overcrowding – Cook in batches if needed for best results. Proper airflow is key.
- Invest in Accessories – Racks, skewers, and baking pans increase versatility. Check out our accessories section for compatible options.
- Monitor Cooking Times Closely – Air fryers cook faster than ovens; check food periodically to prevent burning.
- Clean After Every Use – Prevents smoke, odours, and extends appliance lifespan.
- Consult Trusted Guides and Reviews – Use resources like our buying guide and blog for expert tips and product recommendations.

Frequently Asked Questions (FAQ)
Why does my air fryer stop mid-cycle? Most air fryers have built-in overheating protection. If the vents are blocked or the basket overloaded, the unit may pause to cool down. Ensure proper airflow and avoid overfilling the basket for uninterrupted cooking.
Can I use aluminium foil in my air fryer? Yes, but only if used correctly. Line the basket lightly without covering the entire tray or blocking airflow, which is essential for cooking. Always check your model’s manual for specific instructions.
How often should I clean my air fryer? It’s best to clean your air fryer after every use. This prevents oil buildup, burnt residue, and smoke, and keeps your food tasting fresh.
My air fryer basket smells bad. How do I remove odours? Wash the basket and tray with warm soapy water. For stubborn odours, air fry lemon slices at 160°C (320°F) for 5 minutes to neutralise smells naturally.
Is it normal for my air fryer to make a humming noise? Yes, the fan motor produces a humming sound during operation. It’s normal unless the noise becomes excessively loud, grinding, or irregular, which could indicate a problem.
Why is my food sticking to the basket? Avoid using cooking sprays directly on the non-stick basket surface. Instead, lightly brush the food with oil. Also, ensure the basket is clean and undamaged to prevent sticking.
How can I fix a flickering or blank display? Unplug the air fryer for 10 minutes to reset the electronics. If the issue persists, internal electronic faults may require professional repair or contacting customer support.
