I found it ,and you have replaced thermostats also it looks like .and it will turn off /go dead at times when not even it use correct?
Customer: replied 2 years ago.
Yes. it goes off as soon as I open the door. When it not in use
Expert:  Whrlp Master Tech replied 2 years ago.
and you have tested the voltage coming to the microwave to be able to say it always has voltage even when the microwave is dead?Because the cord comes in the microwave then to a inline noise filter( filters out electrical noise on the power supply lines) then out of the filter to a inline fuse (the fuse is a one time fuse ) when it goes bad it has to be replaced before the microwave will power up again .then from the fuse right to the main control power relay board . so if it is not the board ,I would suggest opening the unit back up and test all the connections on the black and brown wires to the control board you may have a loose wire and the open and close action of the door is making and breaking a contact

I did that the 1st time. Is there anything else that can be done?
Expert:  Whrlp Master Tech replied 2 years ago.
I would take the unit down remove the wrapper /cover and with your meter when it shuts down start testing to see where you have lost voltage at.
