The fuse can be replaced, but the underlying issue should still be investigated and resolved. Otherwise the new fuse will blow also.
If the microwave is not working the thermal fuse may have blown.
When a microwave stops working the problem is usually the line fuse or within the high voltage circuit; either the high voltage capacitor, diode, transformer or magnetron.
Go for a warranty repair anyway. It may be the magnetron, and the clicking is the big condenser discharging. https://www.lg.com/ca_en/support/warranty
