⚡ Quick Answer: Why Is My Air Fryer Not Heating?
In our opinion there 3 most common reasons are: 1. Loose power cable or outlet, 2. Basket not clicked in properly, 3. Overheating sensor triggered. Try unplugging for 5 minutes first to reset it.
🔧 Must Focus on Fix #1 & #2: Check outlet and make sure basket clicks in fully.
1. Check Power Source and Cable
Problem: In some countries, voltage fluctuations and loose sockets are the #1 cause.
Fix:
- Plug into a different working outlet
- Check if the fuse in the plug has blown
- Inspect the cable for cuts or damage
2. Basket Not Inserted Properly - Safety Switch
Problem: 90% of air fryers have a safety sensor. If the basket/drawer isn’t clicked in, it won’t heat.
Fix:
- Remove the basket completely
- Wipe the rails to remove grease
- Push it back until you hear a clear "click" sound
3. Overheating Protection Triggered
Problem: Happens after 2-3 back-to-back cooks. The thermal fuse shuts it down.
Fix:
- Unplug the air fryer for 10-15 minutes
- Clear the air vents on the back and sides
- Let it cool before restarting
4. Faulty Temperature Sensor or Thermostat
Problem: Display turns on, fan runs, but it stays cold.
Fix:
- Do a "paper test": Put a small piece of paper inside and run at 200°C for 3 minutes
- Unplug for 5 minutes to hard reset the sensor
5. Dirty Heating Element or Blocked Air Vents
Problem: Grease and food debris block airflow. No airflow = no heat.
Fix:
- Unplug and let it cool completely
- Use a soft brush to clean the heating coil on top
- Wipe vents to remove oil buildup
6. Control Panel / Digital Display Glitch
Problem: Common in models with a visual display like the 8L Stainless Steel Air Fryer.
Fix:
- Hard reset: Unplug for 5 minutes
- Check for moisture on the control panel
- Make sure buttons are not stuck
7. When to Call a Technician
If you see any of these, stop using it and contact support:
- Burning smell or sparking
- Display is completely dead after testing outlets
- It's still under warranty
