My microwave made by Goldstar, made a "po" noise and the bottom light (over the range) blew and the whole unit quit working. Can you help me solve this problem?

From your description, I would say that trouble you have with the
light knocked out the main fuse, and cut power to the entire oven.
I may be just a case of getting the light fixed and replacing the main fuse.

I used an ammeter to check the fuse inside the yellow plastic snap box. this fuse is still intact. Does the lightbulb have to work for the whole microvave to get power?

[glen65]

No, the light wouldn’t keep it from working.
Based on the description you gave earlier it appeared that
the light developed a short which would have taken out
the main fuse and shut the entire oven down.

Did the main fuse look like this?


You said that you used an ammeter to check the fuse.
You actually would need an ohm meter to check
continuity of the fuse.

I did try to test the continuity of the fuse. the ammeter I had on setting 1x. and It did register a charge. Or maybe I don't know how to properly test this fuse. If I replace this fuse. Will I have to track down the short? so this does not happen again? thanks for your help I just purchased this house and I would rather not spend money on a new microwave if this can be fixed with a simple fuse.

The reason I brought up your meter is
because ammeters are used to measure
electrical current not resistance. Although
some of them do have ohm meters built into them.
If you give me the make and model of your
meter I might be able to see whether or not
what your using is right for the job.
