Air Fryer Error Code E3 – How to Fix!

The other day I encountered an “E3” error code on my air fryer, and it disrupted my cooking process.

I was left with a half-cooked meal and had no idea what to do. 

I decided to find out the cause of this issue along and how to fix it. I found out that the E3 error code often indicates that there is a problem with the circuit board, or the air fryer is overheating. 

If you have faced this error during cooking, I will tell you a few simple steps to fix the E3 error code. I will also share a few tips to avoid this from happening again. 

Error Code E3 in Air Fryer – What Does it Mean?

The Error Code E3 on your air fryer means it is overheating. This is also a potential safety hazard.

Overheating might damage the air fryer or cause the thermal fuse to blow. 

Overheating mainly occurs when you add too much oil, overfill the cooking basket, or block the exhaust port on your air fryer.

This restricts airflow within the device, leading to excessive heat build-up. To avoid encountering Error Code E3, you need to have the correct quantity of oil and food in the air fryer basket.

The exhaust port should also be free from any obstruction.

If you’re faced with the E3 error message, the first thing you should do is turn off your air fryer and unplug it. 

Give it at least 15-30 minutes to cool down before powering it back up. In some cases, the device might need a couple of hours to cool down completely. Use the air fryer only after it has cooled down completely. 

If the error message disappears, you can continue using your air fryer.

Following these guidelines should help prevent Error Code E3 and keep your air fryer in good working condition.

Causes of Error Code E3 in Air Fryers

The reason for this error is overheating.

Let’s explore the main factors that can lead to overheating:

Overfilling the Air Fryer Basket

If you place too much food into your air fryer basket, it might block the airflow, causing the temperature to rise and triggering the E3 error code. 

Keep in mind that your air fryer is designed to accommodate only a limited quantity of food in one batch.

Adding Too Much Oil

Excessive oil can cause your air fryer to overheat, resulting in the E3 error code.

Use the recommended amount of oil for your air fryer model (usually a few drops/teaspoon/one whiff of oil spray).

Blocking the Exhaust Port

Nothing should obstruct the exhaust port of your air fryer. Obstructions can lead to overheating and the E3 error code.

By preventing these issues, you will not only prevent E3 errors but also increase the efficiency of your air fryer.
