The Nuwave Air Fryer Won’t Turn On:

The nuwave air fryer sometimes won’t turn on. This could be due to multiple reasons.

For instance

Power Issue: The Nuwave air fryer demands a constant and stable power supply to properly charge its internal components. Sufficient power will be able to energize the unit’s components and then it will start to operate. However, sometimes, the unit isn’t able to get sufficient power supply, hence disrupting the usual electrical pathway.

Insufficient power supply  may be due to the following reasons:

  • Faulty power socket
  • Broken power cord

Faulty power socket: Sometimes, the power socket into which the appliance is plugged isn’t working properly. It is non-functional and hence not able to supply stable power to the unit. The result is the nuwave air fryer not turning on.

To find out whether the power socket is functional or not, plug another electrical device into the socket and find out if the device still works or not. For instance, plug in the mobile charger and see if the mobile still charges. If not, then it means the issue is in the power socket.

Broken Power Cord:

Insufficient power supply may also be due to power leakage. This leak may be due to the power cord being faulty. Due to mishandling, the power cord may get pressed or bent at weird angles. High temperatures can melt its outer covering or it may also be broken at some points. 

Due to these issues, sufficient power can’t reach the main unit.

Broken Thermal fuse:

The air fryer nuwave has an integrated thermal fuse. The fuse connects to the internal circuitry of the main unit. The fuse’s main function is to regulate the power flow. It acts as a buffer and allows only adequate power to pass through an amount that is not harmful to the internal circuitry.

Whenever there is a power spike the internal fuse blows out to break the internal circuitry so that the excessive power won’t reach the main unit and disrupt its normal functioning. When the fuse blows out, the unit won’t turn on.

Debris Dirt Accumulation:

Every air fryer manual recommends that users clean the air fryers before and after every cooking session to get rid of all the food debris. If the appliance is not properly cleaned, the debris can clog the internal components of the heating element and the fan. This can cause the internal components to malfunction.

Similarly, debris can clog the display controls making them stuckThe grime and dust can even clog the fryer vents. Improper ventilation will cause the unit to overheat. This will activate the unit’s auto shut-off function. Hence, the unit will automatically turn off.

Broken Buttons: the air fryer control panel tabs may become non-functional. This could be due to debris that clogs the tabs and hence makes them stuck.Hence, causing nuwave air fryer start button not working issue.

Faulty PCB: The PCB is the main component that registers your inputs and further commands the internal components to function. Sometimes, the PCB gets faulty due to exposure to liquid or gets burned due to high heat. These can affect its functioning and hence the unit won’t turn on.

Nuwave Air Fryer Buttons Not Working:

The nuwave air fryer display buttons are important for resuming the cleaning process smoothly. Sometimes, the appliance buttons start to act out and may fail to function. 

This could be due to the following reasons:

Insufficient Power Supply: The air fryer buttons need power to work

 If the fryer isn’t able to get sufficient power up, then its buttons won’t be able to work and turn on the appliance. This power issue can arise due to a faulty power socket or due to breaks or bends in the power cable resulting in power leakage.

To deal with this issue, you need to replace both the power socket and the power cable with a new one.

Burnt Fuse: Voltage spikes can blow the thermal fuse which cuts the usual route to the internal circuitry. Hence buttons stop working, to resume their function, you need to replace the thermal fuse with a new one.

Faulty membrane switch: This is the most crucial component in the air fryer. It lies in between the controlled display and the PCB. This is the one that transfers the messages to PCB. If it’s faulty, no matter how many times you press the button, the system won’t respond.

To deal with this issue, you need to open up the unit and replace the membrane switch with a new one.
