The display will change almost by the minute.
It can be programmed and used but after several hours it will lock up and has to be unplugged and rebooted then repeat the process.
One time the microwave came on on its own
Sometimes it will go into the service mode by itself. But the in a few minutes will go away.
At times it will go completely blank.
Can this be the harness in the door.
I need a tech sheet and service manual and service bulletins.
I see this is an issue with this model.
