GE Microwave popping and crackling

[Mike L.]

I had recently found a GE microwave by the side of the road. It is in a very
nice looking' condition, date Jan.2002 1 year warranty model #JES831PWF001.
My second thought was this unit is to nice looking to not have a trouble.
Well, I was right, when I plugged it in the first thing I noticed was that
it had to initialize its smart board, ok fine. Then a message came across
the digital display quoting the word "RESET"(Later I find out what this word
means). So, now I'm setting the clock and everything seems OK at this point.
Now here is the fun part of my post. I go to punch in some numbers, you know
to run the unit and see how it works. The very first number I punch in is
the 1 pad and the thing starts up, runs automatically. I don't get to pad in
any other pads, but then after a few seconds of running it starts popping,
crackling and voltage-current drain through out the house. I quickly unplug
the unit. (In the inside -cooking area- of the unit is a smart chard area
about a half inch in diameter around 2 by 4 at the top of the metal plate).
<----Magnetron



I haven't taking any reading checks yet at this time. I have opened the case
and found the service sheet in an envelope. After looking it over I found a
section that states that the display quote from earlier in my post "RESET"
means power failure.



I have several questions, but here is the first one what is a magnetron?
Stupid question I know! There is RF frequency statement by the model # that
says RF 2450MHz; will this frequency interfere with my 2.4GHz wireless
router?



What is causing the popping, crackling? If I was not in-depth enough please
let me know.

I will also scan the service sheet in a day or two in PDF format and post it
with the same subject heading.



Thanks for your time that it took to read through my post.

This is a troll, right?

If not, I suggest he go read the Microwave Oven Repair Guide at the
site below, especially the SAFETY info.

A magnetron is the vacuum tube which generates the microwave energy. 2.4 GHz
would certainly interfere if it were not contained but microwaves are
usually shielded well enough that this isn't a problem. All consumer
microwave ovens run at this frequency.

What is causing the popping, crackling? If I was not in-depth enough please
let me know.

The paint inside the cavity has been damaged and it's now arcing just as it
would if you stuck a fork in there. Sometimes this can be repaired if you
clean it very well, sand off any oxidation and then touch it up with
microwave oven cavity paint. You'd want to check the condition of the
waveguide though to make sure it isn't damaged. Microwaves ovens are simple,
but they can also be deadly to work on, please read the repair FAQ before
poking around in there.

Mr. Sweet
Thank you for your positive input on my original post. I'm a beginning
repair technician and any help in clarifying my misunderstanding is
appreciated.(Mr. Sweet)
(others)
I have a CET and just because I don't know all the jargon as of yet does
not mean I don't have feelings. For the one who stated "troll" a simple
saying to me like "to much side talk just the problem would be fine" : this
would had been more professional don't you think!

I do already read through the repair FAQ's and quit frequently I should
state. It is very well in-depth.
It is also a start home page on one of my many computers.

(question to anyone)
For this troll thing is this just a polite way of saying "screw off, your
not part of the click so we're not going to help you with your legit
problem"
I look forward to coming to this news group reading a lot, I mean a lot of
these post.
I am very offended by their "troll" statement so whats up with that?

Happy 4th to everyone...
Mike L.

Don't post PDFs to this group - it is not a binary group.

Take no notice Mike. These are the morons we normally call cyber bullies -
they speak and behave in a manner that they don't normally do offline (and
thank christ for that!).

As someone else stated, microwaves can be a rather dangerous thing to work
on. Your best bet if you really want one would be to get one new. If you
just wanna tinker with it, by all means, but exercise some caution.

Welcome to the group anyway.

I'm not a cyber bully, and I speak and behave virtually the same manner
(no pun intended) online and offline. Google on my posts if you doubt
that.

I seriously thought the OP was a troll. After all, who would ask in a
sci.* newsgroup "I have several questions, but here is the first one
what is a magnetron?
Stupid question I know! There is RF frequency statement by the model #
that says RF 2450MHz; will this frequency interfere with my 2.4GHz
wireless router?"

A few minutes with Google would answer both these questions without
wasting the newsgroup's bandwidth.

Hi Travis,

Yep, understood, and certainly valid points in your post. All I'm saying is
that we should give 'em a go every once in a while, instead of an NG full of
people ready to pounce on someone who, granted, probably *should* have
checked Google prior to posting.

No offence meant, and I'm certainly not trying to be disrespectful to you,
so apologies if it sounded like that.

He doesn't know what's it : why he can't ask ? If you hate questions of this
type, please don't read them, but don't read, and don't reply. I don't think
you are a bullie, because I lurked this newsgroup for months and seen your
replyes that aren't replyes from a bully but serious replyes !

Stupid question I know! There is RF frequency statement by the model #
that says RF 2450MHz; will this frequency interfere with my 2.4GHz
wireless router?"

Eheh, this is a ROTFL question ! If the microwave goes on 2.45Ghz and the
router goes on 2.4Ghz it's obvioua that a non-shielded owen makes
interference. But because *all* the owens are shielded, there isn't any
problem !

A few minutes with Google would answer both these questions without

Only 3k. What's 3k ?

No problem, John...and no apology required. Thanks for the follow up.

Have a great 4th.

Respectfully...how did you get a CET without knowing what a magnetron
is?

Asking an electronics repair question on an electronics repair group?
How does that make it a troll?

By this logic most posts here are wasting bandwidth.

If you read Mike's first post he said that the CET was found in an envelope
putted in the owen ;-)

Perhaps it was an envelope full of microwave popcorn? Explaining the
'popping and crackling'?

None of which changes this into a binary newsgroup.

Ok, that statement had me gut rolling on the floor. I'm even having a hard
time typing.

First off, if all I had to do was google it then why would there be such a
need for a newsgroup of this nature?
Second, in my OP I also stated that I was a beginning repair tech(lookin'
for supportive help).
Third, also in my OP I gave some hopefully useful information on what the
"RESET" meant.
OK I'm done with this numbering thing, it's getting boring.
As for the CET it has been a while since I took that test, but I don't be or
recall a question on magnetron.
Anyways, you all I didn't mean to bother anyone. I really have a hard time
some times. I get frustrated,
angry, let down( by myself)all because I want to understand everything and
there is so much information to electronics and the industry.
I originally went to school for my A+ , but this other stuff was part of it
CET, FCC lic, Diploma.
Any more posting would be a waste of BW, right

Your question was too similar to, "How do the pictures get down that wire
thingy into my TV. Doesn't the metal block them?"
