I have to add that low AC voltage will not fire most magnetrons. I have been at several campgrounds where due to the number of campers; high usage (Air conditioning); and poor electrical distribution, the voltage supplied at the campground dropped below 105 volts.
I have a Franks unit that I use in situations like that to avoid issues with my AC and microwave.
