I have a microwave that just died...the control board is dead.

I have had this microwave for a number of years and suspect I could
wire a substitute for the controller...likely a timer.

So is this microwave worth saving?

I note that the new ones look like they have been "valued engineered"
to where they may not be the best for the long run.

Your opinion?

Thanks

IMO no, I would cost at least $100 to fix. is a used microwave worth
$100 when a new doest cost much more than that. On the other hand
repair manuals are available on the web and you may be able to get the
part for $50 or so. I might be willing to try something like that.

The cathode ray tube at the heart of a microwave gradually uses itself
up and unit puts out less and less power as it grows older. Also,
modern microwaves generate more power to begin with than older units
did when they were new.

There is no cathode ray tube in a microwave oven...klystrons or
magnetrons are typicaly used.

Also, they don't "generate" power.

If you have a commercial/restaurant type microwave
oven, I'd say fix it and keep it. Those units are
of high quality and well made. The microwave oven
I'm using at the shop is one I found next to the
dumpster and it's brand new and had the manual and
clean glass turntable inside it! I've repaired a
lot of microwave ovens over the years and have had
to make the "Not economical to repair decision" on
many of them. The problem with many of the control
boards is that they are the most expensive component
of the whole oven. Many of the other parts like the
micro switches and magnetron are the same across a
number of different models and are not as hard to
find a replacement for. If you know your way around
'lectricity, and know how to use basic test equipment,
you may be able to repair it yourself. Please be very
careful because the high voltage inside is a lot more
dangerous than what you would find in a CRT type TV
set because of the high current. The microwaves can
damage the corneas of your eyes if you were to bypass
the safety interlocks and turn it on with the door
open. If you are determined to repair the oven, there
are a lot of resources online to help you. Here's one:

Nope: Magn'E'tron. But that's only spelling.
Unless you are a well accomplished electronics/transmitter technician
don't mess with it.
The control board also monitors that the safety switches etc. are
doing their job.
New m.wave ovens are so cheap it makes more sense, unfortunately, to
dump and get a new one. Frequently around $50 on sale here at say Wal
mart!
Someone once described m.wave ovens "As the most dangerous appliance
ever made"! Please be very careful.

Agreed, it's not worth fixing. We bought a medium size Panasonic for
around $129 that has more power and more useful and practical bells and
whistles than any previous unit we've owned. We've had this one since
2000. It's in frequent daily use and shows no signs of giving up the
ghost.

Microwave ovens don't have cathode ray tubes unless you've installed a
video game into one or perhaps you have a combination microwave oven
and television set.

They use a tube called a magnetron and usually the power supply will give
out long before the magnetron has degraded enough to be noticeable.

It's not worth fixing a microwave, but I do think the older, American
Made ones like my vintage 1989 Tappan are way better than the Chinese
junk you can only buy today. And I also happen to know one other
person with my exact same microwave. Still in service after all this
time.

I feel the same way. My old Panasonic microwave lasted many years.
But the last Panasonic microwave only last slightly more than 2
years. I am wondering whether there is something to do with the
weight of the microwave. My old one weight a lot. The pre-maturally
dead one weight very little even though they were the same size.
There are models in the market: some are very light weight, some are
heavy. May be we should start buying microwave by their weight?

All I can offer is one data point. My nuker is a Magic Chef (kind of a
high-end unit, I think) that I bought used from a friend in 1985. It's
still working perfectly for me.

By the way, this oven is so much simpler to operate than *any* of the
new cheap pieces of shit I've seen around. On mine, you just key in the
time on the keypad and hit "Start". On the one where I work sometimes, I
still can't figure out how to make it cook for a desired number of seconds.

Suit yourself. A high power vacuum tube then.

OK -- The high power vacuum tube at the heart of a microwave gradually


uses itself up and unit puts out less and less power as it grows

older. Also, modern microwaves output more power to begin with than


older units did when they were new.

No. You're blowing the degradation out of proportion. They might drop

But he says his has lasted a long time and the power output does
decline with use.

Because the magnetron is a vacuum tube with a hot filament cathode the
emissive layers of the cathode degrade slowly with time. The result
is weakened emission and diminished power of the tube,

I think you missed my point. Twenty years ago the typical microwave
was 600-800 watts. Today they're typically 1000-1200+

Best do some research. With the make and model information available
check sites like RepairClinic.com for availability and pricing. From
there you'll have a better idea. That site also gives guidance on the
ease of various repairs.

My microwave has a "manufactured" date on it of 1976. It's huge by
today's standards and weights about the same as a small Buick. It's
also as powerful as all heck and cooks very evenly. When it gets
done, it rings a real bell (ding). For the timer, you push in a
button and rotate it so the numbers rotate to the correct time -- no
LED here -- it has real wheels.

Its only 30 years old, so its only just approaching middle age. It
may be the only microwave I ever own if it keeps going another 30 or
40 years.

Now coffee pots are a different matter. My coffee pot died last
year. It was only 17 years old. Seems like they could make one last
a reasonable time. How hard would it be to hit 20 or 25 years with a
coffee pot?

TVs seem reasonable. Someone gave me my bedroom TV about 18 or 19
years ago, so it's probably only 25 or 30 years old. The good part is
that when I have to program the replacement remote, the code is "000"
which is easy to remember.

Unfortunately, my downstairs TV was only about 10 or 12 years old when
it died. Hard to tell how the new one will last, it's only a couple
of years old. But somehow I doubt it'll make it to the 30 year mark.

A lot of the old stuff didn't come with the bells and whistles that
are standard today, but I think they were made to last. Now, too much
is disposable but in some ways that's okay because the technology is
changing so fast.

Unless you are an electronics whiz, and have an identical unit with a
known good board to scavenge for parts, no. It's unlikely that you
will be able to obtain parts, and even if you can, you may find that
the parts are far more costly than replacing the unit, even with a
higher grade model.

First off, there are more places than Walmart that sell microwaves.
Try an appliance store.

Second off, yes they are value engineered. Think about how much your
old microwave cost and how long ago that was. Look at what a new
microwave costs, and how much less a dollar buys you now than then.
Something had to give, and that something was the quality and
reliability of the product.

I assume you're happy with it, but a 650 watt oven is sadly under-powered
by today's standards. I'm sure that there must be some current models with
a taller cabinet than others.

We have two m/w's, one 1000 watt over-the-range model which I consider
perfectly adequate, and a second 1350 watt countertop model which I really
prefer. The over-the-range unit has a tall enough cavity to accomodate any
container I use, and is tall enough to handle two levels of cooking if the
rack is inserted.

It's nice to save money, but I prefer advances in technology.

My parents bought a microwave before we moved in 1975, I think it was. I
remember them wondering if it would fit under the cabinets, in the new
house. It did, and it's still there. Dad had to reoil the blower fan a
couple times over the last decades.

Mine, my parents bought for me in maybe 1991. I've still got it, and it
works fine.

Unless you like to heat and eat rocks, more power isn't desirable.

I rarely use full power. I'd rather eat my food than scrape it off the
walls of the microwave oven. I cook my morning breakfast cerial at
power 4 and use 5 or 6 for everything else.

No shit sherlock.

However if one has to run it at a 50% duty cycle instead of a 70% duty cycle to
prevent the food from ending up along the walls of the microwave oven, then the
increased power isn't providing the slightest benefit.

I had the same problem until I discovered food-covers.

For example, a lid from a Folger's plastic coffee "can" fits neatly over my
soup bowls. An upside-down tupperware bowl fits over saucers. And so on.
When the food explodes, bumps, or turns inside-out, the mess ends up on the
covering device, not on the MW's walls.

The the lid pops off, and the food ends up on the tray.

Sorry. I prefer my food in a dish, not scraped off the tray.

Variable power (duty cycle for salty's anal analysis) has been around since
the 70's with good reason.

Real microwave lids exist, and while solid on top, they are ventilated
on the sides. No popping off. It'd definitely be dumb to seal a
microwave dish with an airtight cover.

I'm not in disagreement with nor critical of your approach, but most
people are far too impatient to wait five minutes to eat, when they can
eat in 90 seconds.

There are lots of things that I cook at power 2, 3, or 4. I also cook
virtually everything covered, so there's no mess in the oven cavity
regardless of power setting. However, full power at high wattage is great
for quickly bringing liquid based items to a boil, then lowering the
setting for longer cooking. Not to mention that the higher the wattage,
the better popcorn pops and with virtually no unpopped kernels. This is
true whether it's prepackaged m/w popcorn, or using a m/w popcorn popper
with regular popcorn, with or without oil. Cooking bacon is no messier at
high power than at lower settings.

Today, cooking times for packaged frozen foods are usually calibrated for
ovens of 1000-1200 watts. Take a look at the packages. The final product
cooks better at the appropriate wattage, rather than having to adjust the
timing up to compensate for low power.

We jave 650 watt Amana microwaves in our break room at work. I *hate*
cookingin them.

Chuckle. Not always. This house came with an over-the-stove micro, which
I hardly ever use, in favor of my old Samsung. I tried covering a dish
with a paper towel once, at a medium power setting, and the paper towel
caught on fire.

Bullshit. And what the fuck problem do you have with the concept of
somebody using the variable power setting? Why does using a microwave
oven at anything but full power give you such a hernia?

Hi there sa......@ dog etc.

And probably way more than I have also, so I will defer to your
greater technical/electronic expertise.

But it really does worry when someone who possibly doesn't know DC
from AC; the kinda of competent, perhaps, do it yourself person, but
who posts on this news group that they are measuring 38 volts using a
DMM on a dead wire due to capacitive pickup of AC voltages etc.

And then opens up a 1000 watt microwave (essentially a very high
frequency radio transmitter inside a metal box) with DC voltages of up
to 5000* volts and ampere capacity of at least 100* milliamps or more
(certainly enough to kill somebody) and starts tinkering and exposing
themselves to microwave radiation.

Also if they do fix it perhaps not getting the cover back on with
those RF sealing edges, and not realising that it matters?

For example: One person said something about getting a few screws to
put a microwave cover back on. That's rather like digging around in
the garage and putting whatever kind of old engine oil one finds into
a perfectly good car motor! Most wouldn't do it eh?

So yes; while I am an older and somewhat out of date (tube era)
electronics technician and I've fixed a few m.waves, if my neighbour
(who has only a few clues about 'any' electrcity) started messing with
his microwave I'd stop him for his own safety.

Safety first?
Reference ' * '; that's 43 times the voltage and at least some 3 times
the current that GFIs are required to operate for human safety. In
other words while most posters are no doubt smart and sensible and
apart from microwave radiation (you wouldn't stand in front of a
radar!) they can kill you.

So; not preaching just warning. OK?

Don't remember for sure, but probably some sort of canned pasta glop, or
chunky soup. It was a corner that lit off, not a grease smudge. Almost
like a kitchen match would do.

No, I'm not curious enough to try to recreate it. That damn smoke alarm
is LOUD.
What would Mexican food have to do with it?

WTF is your problem???? I don't give a shit WHAT power setting someone
uses. I just merely made a suggestion. I've been using a paper towel
for YEARS and have NEVER had to clean the inside of MY microwave,
asshole.

True of conventional microwave ovens, but not the Panasonic Inverter
models. All power settings from 30-100% run the magnetron continuously,
but vary some tube operating parameter to adjust the RF output. The 10%
and 20% settings are implemented by 1/3 and 2/3 duty cycle at the 30%
power level.

I can cook a single egg in an open bowl in the Panasonic at 30% power
without it exploding.

I *love* my Panasonic Inverter. I've had my countertop model for about 5
years. When we moved into a new house a year and a half ago, it was
equipped with a very nice full-featured over-the-range microwave. I kept
the Panasonic since we had plenty of counter space, and I rarely use the
other unit unless what I'm cooking calls for full power, or using just the
"keep warm" setting, which works quite well.

Keep in mind that not all of us (in fact, hardly any of us) view this
newsgroup through Google Groups, and therefore message numbers mean nothing.

That could be you used a paper towel made out of earth-friendly, eco-pure,
save-the-whales, GoreGod, recycled materials.

Sometimes there are warnings on these products to NOT use them in a
microwave because they contain metal particles. For example, cardboard
thrown into the recycle vat often has staples remaining in them. Foil labels
and other sources of metal abound.

These metals are ground into undetectable bits and mixed with the good
stuff. When the result gets to the microwave, well, there you are.

Personally, I'd question repair of an appliance over 10 years. A new
microwave is might be $300 (or less) with improved features. You are
right, though, about many things made today don't last. If you enjoy
tinkering (or can't afford a new one) go for it!
