On the drawingit shows it to be 15 K and in perentises it shows (30W) so I
would try the 30 K and see what the voltage is and if its to low, try the 15
K, its a 2 watt.

My blown fuse Experience With a Sharp Carousel Microwave Oven (Model R-330AK)
[cira Dec. 1997]:

My wife told me the microwave oven didn't work. Checking it out it seemed to be
a typical fuse problem. A few

years ago we had a similar problem with this same oven. However, after I
replaced a clearly blown fuse (20 amp,

ABC type) the oven would not work. It was as if the fuse had blown again (it
hadn't!) In frustration, I took it

to the Dealer's Repair Shop to have it really fixed. When I went to claim it a
week later I was told I had

damaged the Display Panel in my attemped fuse repair and the bill came to $145!
I said, I didn't care if the

display worked perfectly. I just needed the basic power functions. $60 allowed
me to have just the fuse replaced!

This time I knew the fuse had blown and I had not damaged anything within, but
the replacement fuse made no

difference. Your web site info got me to probing the circuits with my Ohm
Meter. There was continuity through the

power cord prongs to the leads inside of the cabinet. Continuity on the black
wire ended on the output prong of

some kind of white plastic device screwed to the inside back of the cabinet. I
thought this might be some kind of

safety power isolation device. Once I removed this device, I could see it was a
Cutoff Switch which would cut

power to the oven if the lower left cabinet screw was loosened (required to
open the case). One of the sheet metal

screws was two millimeters longer than the other three! If you didn't notice
where the long screw came from, you

have only a 25% chance of fixing your microwave oven fuse. Now, when you take
the oven to your friendly repair

man, he knows you had the case open (forbidden to all but PROPERLY QUALIFIED
REPAIR PERSONEL).

I don't think Sharp Company planned to give their customers a Golden Screw Job
for $1 fuse replacement. Their

lawyers probably insisted this was a way to protect 75% of the DIY'ers from
injury and sueing Sharp for not doing

something to protect them. Paranoid? Who, me? Thank you for your site.
 
Given the number of unqualified people that try to repair Microwave
ovens, a cutout switch is entirely justified. The fact that it wasn't
obvious should have been a clue that you shouldn't be messing with it.

Poking around the guts of a microwave without understanding the very
lethal voltages that can be present is just plain suicidal. You did
realize that a microwave is far more lethal than a TV, right?

More than one person has met an untimely end to their existence due to
their ignorance of the lethal voltages in a microwave. There is dangerous
and there is hazardous, and then there is absolutely lethal. Microwaves
fall into the last catagory.

That's right -- you can't cook mozzarella sticks in a TV!
