I have a Goldstar MV-1515W microwave installed over the stove vented externally. I want to replace it. Goldstar became LG. I contacted LG and they were unable to tell me whether a new model will have the hole in the wall, in the same place. I am unable to find the template used many years ago to cut the hole and hang the microwave. If I had the template I could compare that to new models.
Is there any standardization with regard to the hole for externally vented microwaves?
