How could something so small be so important? Very Important!

Ihad a customer call yesterday and ask how to replace their microwave'sfuse. Good question! It's really rather simple. Now, a fuse doesn'tbreak for no reason at all. There is usually another underlying problembut usually it is because of a power surge. So, keep that in mind whenreplacing your fuse that you may have another problem if this isn't aquick fix.

First you have to find the location of your fuse. Makes sense! They usuallylook like the one pictured above and range anywhere from one to twoinches long. When purchasing you are looking for a "ceramic microwavefuse".

You willneed to take off the cabinet or shell of your microwave with twoscrews. A simple screwdriver will work. Now, use your power cord as aguide and find your inner workings. You will probably see a computer orpower board where you will see what is called a fuse holder.

Next,examine the fuse. If you have ever seen a blown fuse you will knowexactly what this is, if not, you are looking for burned markings onthe ceramic or white part of the fuse. You may also see melted parts orit may be solid black. You have to look for residue kinda like when afirecracker blows. If you have an ohmmeter go ahead and test it. If youcome up with a zero you are good but any other numbers means you need anew fuse.

Next,simply purchase a replacement fuse and replace. Very simple. Now, putyour microwave back together and give it a whirl! Heat a cup of waterto test. Usually all is well, you now have a happy microwave ready todo some nuking!
