Changing a fuse, Hard?
well its not very hard to do,,, but,,, what caused the fuse to blow?
what fuse has blown as there are at least 3 of them in there, none of them are the same size as a 13 amp plug and most are of the slow blow type,,, even the hight voltage fuse!!! (ei:1000's of volts!) if a fuse has blown its most likely to be the unit getting near the end of its life, and sufferd whats called a "flash over" maybe on the capacitor or the megatron both would pop a fuse, but it will only do it again!! and that next time it could go with a big bang and stink your house out for weeks with a burning smell!!!! and if you dont know what not to tuch inside of this microwave dont go inside of it, it could easly kill you, even with the plug pulled out the wall scocket, there will still be 1000,s of volts kicking about inside of it,,, whats your life worth??????
microwaves are only £50.00p up now,, play it safe buy a new one
