This microwave will shut off mid cycle. The control will stay completely blank and nothing will happen. If you leave it unplugged for a little while it will cut back on and functional normal for a few cycles. Is the the control board going bad, or is it the mag tube interfering with the board and shutting it down. Are there any test I can do to check this, as everytime I am there after I plug unit up it will work fine for many back to back cycles

Hi. This does sound like a control issue. Unfortunately, unless you can catch the unit in its failed state you will not be able to do any test to diagnose the issue. With the unit failed, with no display, you could check for proper voltage to the main relay on the control board. It should be 120v. IF power is there then you have a faulty board. If not you have other issues. I would check for voltage loss at the outlet while unit is running. Check for faulty door switches or a burnt filter board/fuse holder and wiring also.
