Ok sounds very much like the control board has failed, this is what controls everything on the appliance. This will need to be replaced. This is located behind the metal panel in the rear of the unit, once all the screws have been removed you will have access to the control.
I strongly recommend you buy the parts from the link below, They offer a year warranty and will allow you to return the part even after it has been installed, Other suppliers offer no warranty or 90 days and will not allow electronic parts to be returned.Click here to order the control
