The five elements of the kitchen in Feng Shui belong to fire, and the five elements of the microwave oven also belong to fire, so the two are relatively unrelated.
In fact, the single electrical appliances that have an impact on people are TVs and air conditioners. When looking at Feng Shui, please note that other microwave ovens, refrigerators, etc. will not be in places where people wait for a long time, so they will not have an impact. . Moreover, if the kitchen is a fire, as long as the kitchen door does not face the bedroom door and bathroom door within a short distance, the placement inside will not have any impact, including the fact that the stove and sink are opposite each other.
Hope it helps.
