Question about LG MV-1444Y Microwave Oven
When the high voltage capacitor fails, it almost always shorts, always resulting in a blown fuse.
Your problem is most likely a shorted / blown high voltage rectifier diode.
Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first:

To order parts, the best i can suggest is to call the number in your owner's manual or have a local appliance parts store match them up.
