Today I got a new microwave because I have an extended warrantee and now I have Microwave #3 since 2018.
the first one died after 1 year.
The second after 18 month now we will see how long this one works.
The microwave works fine until the day its starting tripping the breaker 
The tripping happens to 95% by opening or closing the door!
Again the microwave gets 5 stars nothing wrong but the mechanics are weak.
