The easy answer is 9 times out of 10 the console is bad.
What are your symptoms?
If the unit appears completely dead (no lights, no response) you can disconnect the console from the board on this model, then close the door and if the board is good the unit will go into drain after the door is closed. Also if it is completely dead be sure and test for 120 volts between the hot line and neutral and check the thermal fuse on the control board to make sure it is not open.
If some buttons just don't respond and some do, most likely it is the console.
To do any further diagnosis you will need a pin chart showing which terminals correspond to which buttons, and from there you can use an ohmmeter to test each button on the console. This pin chart is sometimes on the tech sheet located behind the bottom panel.
