My microwave oven is externally vented. Should I need to replace this oven, can I rely on the external vent location on the back of any new microwave oven of the same size (of any brand) being in a standard location that will line up when installed in the same place over my range?” This started off as an addendum to a question I posed and updated back on 9/3/2020 about the night light feature not working properly on my current oven and apparently is a stumper, so I’m considering replacing the appliance.

@moe_r they are not in a standardized location. Most of them are in the same general area. If you have some “wiggle” room for the vent where you currently mount your MW, it will be okay.
