I had about five cases where the magnatron of various models went faulty. In all of these one can see the magnets on magnatron were cracked open. When replacing new magnetron, it heats up very fast and unreal. Fan is working and air flow coverd. I replaced the capacitor, diode and even the transformer with no sucsess. On those new repacements, when i try another new magnetron i find the same results. I know, this make no sense. Is there any one out there that can help?
