Hey mate, it might be more then just a fuse. The fuse is mearly there to cut power and prevent a fire under fault conditions. There are also two fuses in microwaves. A 110/240v mains fuse and also a 5kv fuse on the transformer.

Such condition can be a burn out magnatron, transformer, HV rectifier diode or HV capacitor. I'd recommend visibly inspecting and also testing the components. BE CAREFUL though. The HV capacitor can hold charge for a long time and can kill you. Make sure you discharge it safely.

To open the microwave, you'll need a PH No.2 screwdriver and possibly a security Torx 10 screwdriver. There will be 4-8 screws on the back and 1-2 screws on the side. Once they are removed, pull the case towards the back and lift it. The mains fuse will be on a PCB where the mains cable enters the microwave.

If you need any further help or advice, comment and I'll help you out.

Hi,

You also have to be aware that there is always a reason why a fuse blows.

It could be fatigue (fuse wire not connected properly in fuse assembly or incorrectly rated fuse inserted in the first place - holds but over time the stress of carrying the extra (for it) current burns the fuse wire) but that is rare and it is mostly due to a problem in the circuit that it feeds.
