Question about Sharp R-7A85 Microwave Oven
The aluminium foil has created a short on the magnetron - the device that generates the microwaves . The magnetron failed and in turn has shorted the power source's transformer - the sizzle you hear is the secondary high tension coil burning away when the unit is powered. This of course triggers the fuse every time you try it.
There is nothing more than can be done to save this oven , the damage is too extensive. Just junk it and get a new one.
