LG microwave not working fuse is ok - LG Microwave Ovens

Problem is due to faulty power supply in the PCB assembly,if you are technical person check the power supply components other wise consult technical person.

did u check plug n internal fuse..lol. my diode that went to earth was the culprit coz my microwave leaked into base and diode to stop leakage to earth had blown

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.

Change Bridge Rectifier Diode And Capacitor Without Test by Meter,Some Time it will licks,Check All Connected Parts,And Last Is Transformer

Check the microwave fuse. It is in a plastic fuse casing on a wire. The fuse is about 1/8 dia x 2inch. Be sure to replace it with exactly the same rating.

it may be an internal fuse that popped. try a lamp or something in the outlet. if that's ok, it's probably a fuse inside the microwave.

Chances are it is a standard 1/4" x 1-1/4" (6.3mm x 32mm) but I would suggest measuring it to be sure.

Hi! it seems that your microwave oven, magnetron is not working, check the fuse.

by replacing the fuse you meant the house circuit fuse or the microwaves internal fuse? and by conncetions your talking the internal wiring inside the case of the unit or wiring from the plug? if not its your 15 or 20 amp ceramic fuse inside the unit,if thats blown replace,but chk h.v.diode,v.v. cap,triac,control board, mis-adjusted interlock safety door switch,and lastly the mag could be defective

Check the fuse between the highvoltage terminal of the transformer and the hivoltage capacitor. If it is Ok replace the magnetron.
