Ok, when you close the door the display (time) flashes on for a moment then off. The controls/keypad does nothing. I am thinking new control board for sure and maybe a door switch? It was working properly 1.5 weeks ago. Any help would be much appreciated.

Check the door switches for continuity by opening and closing the door. Always remove at least one wire from the switch when checking for continuity. If the switches check good, Take the control board out and visually inspect the board. When the display turns on for a moment it usually means there's a broken solder joint somewhere or a broken trace. If you can't find it you'll need to replace it:

Thanks again Rick. I plan to purchase a control board and switch, and return if I can find the problem. Andy

There's four microwave door switches

Oh, I did not know that. All the same switch? Also, if one is not working, would that interfere with the controls, and display?

No and probably not.
