If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If it goes dead or blows the breaker when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

Please feel free to contact me directly if you need more help. And please mention your model number when you write.

We're happy to help and we appreciate your thoughtful rating of our answer.

You almost certainly have a shorted high voltage capacitor.

See the safety warnings and help information here.

Chances are you will have to remove the oven from the wall to replace it.

Mike - Unplug the unit and unscrew about 4 screws on the top and then the side panel and the fuse will be in that location.

Note: If the fuse looks brown, it's definetly blown, you can get the same fuse at your local Radio Shack for about $0.97. hope this helps

Fuse keeps blowing.


It appears like the high voltage capacitor is shorted or the diode connected to the capacitor. You might want to check the monitoring switch as well if the capacitor and diode are good.

Fuse keeps blowing.


couple questions -
what else is on the circuit,
and what current does the oven need

there are whirlpool over-range models with
1200watts of microwave,
1500watts of convection power, a
60watt bulb and a
375watt fan

over 15amps -20amp circuit needed

if you inadvertantly replaced a higher current fuse with a 15amp fuse, it will blow every time.
the install guide http://www.whirlpool.com/assets/pdfs/product/ZINSTALL/8206589.pdf reccommends 20amp
not a solution, something to check,

Fuse keep blowing up


You have a short in the system. removeing the fuse was not a good thing to do. The fuse in a microwave helps keep the system from an overload which can and I have seen this blow-up. The micro pump inside might have a dead short it,
