The broken switch behind the knob:

First, learn how it works. You can see one knob on the top of the appliance. You may think this is the actual part that provides input to the device, but this is not true. 

Because when you rotate the knob or set any mode, the knob rotates the switch located behind it that is not visible from outside. 

This is a small switch that delivers user commands from the knob to the control board. In case this switch is broken or does not work, the knob will not work.

The knob switch has a broken connection with PCB:

The switch behind the knob has a connection linked with the printed control board of the Cuisinart air fryer toaster oven. 

This connection delivers input from the knob to the control board when it rotates in any direction. 

In case the mechanical connection between the PCB and switch is broken or has some problem with the delivery command, you will see no functionality with a knob.

there might be a problem with the control board. Suppose the knob is providing input correctly to the control board but the control board is not following the command. In that case, you will see no functionality in the Cuisinart air fryer toaster oven. 

This may make you think of an unworking knob. To know if the control board has a problem or not, try to analyze what is working with the knob and what’s not.
