The cooling fan on an M6040SC runs whenever the magnetron does and for a period afterwards, and a bearing that has started to complain announces itself as a rising whine during and after cooking. It is a part worth replacing when noticed rather than when it fails, because a magnetron that loses its cooling does not last long, and that is a much larger repair.
