It appears that all functions of control panel are working, however on any selection made when the door is closed and you press the start button the door no longer locks and pause appears in the display and washer doesnt start
That is not a good Frigidaire model number, but I am assuming you have a basic front loader. The problem is the door is not locking so the machine will not operate. This can be a problem with the door lock assembly, the wiring to the door lock assembly from the control unit or the control unit.
Look inside the lower service panel and see if there are tech notes that will show you how to do some testing and diagnosis.
