What Does E3 Mean On My Ninja Air Fryer? (PROBLEM SOLVED…!)

E3 on a Ninja Air Fryer represents an error code!

E3 on a Ninja air fryer represents an error or malfunction code that the air fryer uses to communicate that the aequipment has overheated at some point in time.

Ninja air fryers are meant to cook you low-calorie food with the essential crispy touch that you love to experience in otherwise deep-fried cooking!

Modern air fryers are designed with certain features that enhance the end user’s experience of the product.

In order to further understand what E3 means on the Ninja air fryer, we recommend going through the construction & control details of the equipment.

What are Ninja Air fryer’s Inherent Features?

Ninja air fryers have a built-in smart electronic control system that corresponds to the performance, operation & safety aspects of the air fryer.

These controls are logged into a certain set of programs that the equipment is constrained to follow from the start to the end of the cooking cycle.

1. Performance Controls

The performance of the Ninja air fryer is instantaneously monitored by the machine’s in-built control system. Pre-defined feedback is continuously fed into the air fryer’s controller, where the set parameters are examined & necessary actions are taken to maintain the equipment’s performance curve.

A list of performance controls is provided below;

1.1 Running check

An air fryer’s run operation is constantly under surveillance by the central controller that ensures the following;

  • Main power supply
  • Secondary DC voltage for instrument circuit
  • & other necessary functions of the air fryer are being performed as per the manufacturer’s design.

1.2 Heater performance check

The heater in an air fryer is the core that produces heat energy essential to process the raw food inside Ninja Air Fryer.

Heater performance check ensures adequate heat energy is produced against the power consumption by the device.

It also guarantees the heat dissipation from the air fryer coil to the raw food.

1.3 Fan performance check

Fan performance is linked with the heat dissipation inside the air fryer. Primarily from the air fryer heating coil towards the raw food for moisture removal & ensuring food is processed.

The healthy operation of the fan is a vital performance check to ensure the Ninja air fryer’s reliable operation over the course of usage!

1.4 Air temperature performance check

The air temperature inside the air fryer is linked with both the performance of the heater in converting power to heat energy & the air blowing away the necessary heat.

The heated air will essentially come in contact with the raw food’s moisture and ensure evaporation and dissipation of the heat.

This, however, is the most critical performance parameter that the controller ensures as the amount of heat required to cook the food varies appreciably over the course of meal preparation.

In the initial phase, more heat is required which further reduces with the passage of time as moisture removal takes place.

A ninja air fryer is the best in class and has superior air temperature control that ensures fresh & crispy processed foods!

2. Operational Controls

The term ‘operational controls’ illustrates the parameters that are essential to ensure the operability of the Ninja air fryer.

These controls are again incorporated into the air fryer’s controller.

The pre-defined parameters are checked and processed & necessary actions are taken to ensure the smooth operation of the Ninja Air fryer.

2.1 Constant Temperature monitoring

Temperature monitoring during, routine operation of the Ninja air fryer is carried out via temperature sensors & transducers integrated into the air fryer.

Failure of any component or malfunction can lead to a bizarre situation, with the air fryer producing unwanted results!

2.2 Constant Timer monitoring

The timer in an air fryer controls the overall duration, for which the air fryer is intended to remain in operation.

A faulty timer can result in both; uncooked or overcooked food that the user may not have been craving.

2.3 Operational logic control

The operational logic of the air fryer is patent and never disclosed by the manufacturers. However, it is of prime importance and helps you cook your meal with ease & comfort at the touch of a button.

Ninja air fryers have the best operational logic control, which adds to the user experience of the product. This is why the majority of the users prefer to stick to Ninja air fryers compared to other brands available in the market.

2.4 Humidity control

It is an optional feature that certain models of the Ninja air fryers are incorporated.

This function is really unique and keeps you updated on the readiness of your meal by analyzing the air quality inside the air fryer. Specifically in terms of the humidity of the air.

A less humid air would mean the moisture is now removed and the meal is ready to be served.

3. Safety Controls

Safety of the end user & the air fryer itself is of prime importance to the manufacturers since it directly affects the manufacturer’s reputation & sustainability in the masses!

Below important safety features are integrated into the modern Ninja Air Fryers!

3.1 Permissive to start

‘permissive to start’ refers to the key essential parameters & protections in place before the equipment is good to go for operation.

This may primarily include;

  • Proper assembly of the air fryer
  • Availability of the AC voltage
  • Availability of the transformer for DC voltage
  • Heat/Temperature senors
  • Overload protection etc.

3.2 Thermal sensor control

Overheating control in the Ninja air fryer is scanned through a device that senses the temperature of the internal air and trips the air fryer proactively to avoid the unforeseen.

The sensor on an erratic behavior may cause undue shutting down of the device or a false alarm.

3.3 Sensor health check

Sensors inside the air fryer are double-checked by the controller & ensure their availability as a safety feature.

The controller may not allow the air fryer to turn on in case of malfunctioning of any of the sensors inside the machine.

3.4 Electronic circuitry check

Healthy operation of the air fryer is only possible when the electronic circuity of the air fryer is constantly monitored and feedback provided to the control.

A malfunction or wrong signal can lead to fires or damage to the equipment apart from abnormal air fryer operation.

3.5 Overload protection

Air fryers have overload protection available in the form of a fuse that gives up in case the device is short-circuited or operated on high load.

The exhaust of the air fryer if chocked due to food grains, dust, or the presence of cloth or any other hurdle will cause overload operation of the device.

This protection is the lifeline of the air fryer

3.6 Electric leakage protection

Since the device operates on an AC current, the chances of electric leakages from the device or the cables always persist.

ELCB provided in the device can shut down the equipment safely without compromising the equipment and the end user.

Error Codes – Defined

Why is E3 displayed & how to get rid of it?

This error code helps the end user & hence the services team to figure out effortlessly what went wrong with the air fryer.

E3 error code states that the air fryer has been overheated at some point in time due to excessive food placed in the basket, clogging the output of the air fryer, or oil has been excessively used.

This issue can be rectified by following the below steps

-> Disassemble the air fryer

-> Check if the internals are clean

-> Remove any deposition on the sensors

-> Go to settings & factory reset the device

-> Go to Menu and provide temperature range/time

-> Check the basket levels to be within the limits marked

-> Take an attempt to turn on the device

-> If the error code appears, factory reset the device

-> Follow the steps mentioned in the manufacturer guide

If the issue still persists, please visit your nearest after-sale services shop to rectify the E2 error display by replacement of the thermal fuse.

Are there any other Error Codes apart from E1?

There are other errors as well that the Ninja air fryer displays to communicate the malfunction. This eventually helps the repair team and the end user to identify the exact root cause.


Air fryers cope with certain issues during operation & they are built with certain key features that enhance the user experience of the product in terms of performance, operation, and safety.

There are certain error codes that the air fryers display when they stop working. E3 error code refers to the overheating of the device due to excessive food in the basket or clogged output/vent

We recommend following the OEM instructions in the handbook to resolve the E3 errors.
