Ok
Heres how and it's easy enough. and you avoid the capacitor Nasty little doodads they are :)
Remove your microwave from the kitchen cupboard housing { A helper is needed here to remove the plug from the wall socket } Remove the outer screws from the casing { Don't remove the screws in the chromed panel }. Theres 2 on the side too to be removed. No need to remove the outer casing just lift it and the fuse is there { If you are lucky you can just lower it back down but it's likely the front of the casing will come out too { It fastens under the front trim }
put the screws back in and bingo.
The fuse is 10amp 20mm
