Default Just gutted a microwave oven

The fan's job is more than cooling the magnetron. The blades of the
fan are used to disperse the microwaves inside the oven to help
prevent cooking hot spots.

How do the blades disperse the microwaves?

The entire chamber is a resonant cavity. The entire space is inundated
with microwaves.

The moving blades change the resonant mode of the cavity.
This changes the location of the hot spots.
