    THE FUSE WAS BLOWN AND I USED A SCREWDRIVER TO MAKE CONTACT ACROSS THE FESE TERMINALS AND IT SEEMS TO HAVE A VERY BAD SHORT I THINK IT WILL BLOW IMMEDIATLY. THE UNIT BUZZES QUITE LOUD AND THE SCREWDRIVER ARKS LIKS A DEAD SHORT.

    When does the fuse blow? - almost immediately after you hit the Start to pad to begin microwaving? - or a few seconds later? - or when you open or close the door?

When you press the Start pad to begin microwaving:

- does the fuse blow immediately or almost immediately?

That would be a shorted high voltage capacitor.

- does the fuse blow a few or several seconds later?

That would probably be a shorting high voltage transformer, or possibly the magnetron.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

Unit not powering up


There is a fuse located behind the control panel.

 

If that is good, or replacing it does not fix it, you may have a problem with the control panel, which we repair nationwide for $39.95.

 

We have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk
