[COLOR="Blue"] Should I start at the auger motor and is there a way to check that or would it more likely be the actual circuit board?[/COLOR]
Cannot say.

I would start by ensuring that the auger motor is OK.
Check if it gets 120 volts when it should.
This may be difficult to do because getting to test points may be a pain.
Also double check that it is a 120 volt motor.
If it has voltage and does not turn then replace it.

You could remove it and then check for the voltage at the correct pins at the receptacle. This should be easier.
