Question 1047238
as far as i can see, you won't be able to turn it once it's in the space.
that's because the length and width is 21.9 inches and 17.35 inches which makes the diagonal equal to 27.93 inches which is greater than 23.5 inch width of the space.
i made a mockup to confirm my calculations were correct and it confirmed what the calculation indiated.
as you try to turn the microwave in the space, your diagonal measurement will prevent it from completing the turn.
this assumes that the microwave is horizontal when it enters the space and has to remain horizontal as you turn it.
