• ** REMEMBER! **The microwave can still shock you even unplugged!!

    ALWAYS discharge the high-voltage capacitor first if you even think your hands will come close to any HIGH VOLTAGE components.

    Jeff mentions this: Anything in the high voltage ( magnetron, capacitor, diode, wires to and from ):
    ...Use a metal ( not the shiny chrome type ) screw driver with a insulated handle to short across ( touch both at the same time ) the terminals of the high voltage capacitor to discharge it.

Anyone had their microwave fuse blow?

One day our Magic Chef MCO153UWF was completely dead. Checked the outlet in the cupboard above. It works.

Did some googling and found out that MWs have ceramic fuses. Located it and took it out and as you can see it has a black line around it. I guess that means it's blown.

Bought some new 250V 20A fuses for $2 at CT and put in the new fuse and plug it back in. Immediately the MW beeps and display comes on. Open the door and fuse immediately blows.

I read somewhere on yahoo answers this exact same thing happened to someone else. And on kijiji there is a guy selling the same model who says the door switch has a problem and it's doing the exact same thing. But only occasionally, not every time.

So has anyone else had the same problem? And the fuse kept blowing? I figure I'm out of luck because it's not worth the money and effort to try and fix this. I'll check around kijiji for a while and see if I can get the same thing for $40 or so. The bracket is already set up and I wouldn't want some other kind of above range MW because I assume I'd have to set up a new bracket assembly and I'm not all that handy.

Want to delay the purchase of a new MW because I'm hoping to get a promotion at the end of the year and bump up my pay. Then I'd consider all new S/S appliances. The oven died on me in Nov. and I replaced with a similar one for $150.

I suppose both dead appliances are close to 10 years old if not older. Only moved to this house in July.

Thanks for any input.
