The ceramic fuse is located inside of the cabinet near the entry point of the power cord. It is the magnetron that creates the heat so whilst it may not be the magnetron itself that is the problem but perhaps some components that supply the magnetron you could be voiding the warranty on the magnetron if you attempt to open the microwave to find the cause.
