Question about LG Microwave Ovens
Model # lmv2083st
Fuses are normally internal on Microwaves and opening the cabinet exposes dangerous voltages, even when disconnected.
The fuses used are 'Ceramic' and look like this.
However, just replacing it may not fix the problem, if you have a shorted component inside, it will need to be repaired by a competent shop/technician.

It sounds like the magnetron may have
either failed or is not being supplied with the extremely high
voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.
