GE Microwave Transformer

    I have a GEJVM1640WB002 microwave that was manufactured in October of
    1999. I have had it since November of 2001. Last night while trying
    to warm a very late night sack, the microwave produced some very
    intense crackling sounds and gave off a very foul odor. After tearing
    into the microwave, I found one side of the transformer was burnt
    crispy. Obvioiusly the transformer needs to be replaced. Any idea
    what the cause may be? After looking on the GE website I found the GE
    P#WB27X10254 transformer to be an outrageous $146.35. The transformer
    itself is a Samsung SHV-1640UC. It has the words Dong Yang Power
    Systems INC., LLC on it as well and another part number J1012HP. Does
    any body know where I can but this transformer with out shelling out
    all that money to pad GE's spare parts departments profits? I know
    large companies make bank off of spare parts orders.

    Even if you find a transformer for practically free, in the long run
    it'll be cheaper (albeit maybe not as much fun) to just buy a new
    oven. Of course, you'll still have the old one, which you can then
    take apart, cut off the burned windings from the old transformer
    and experiment with it - try and see if the primary's intact, and
    when you're pulling the burned wire out, see if you can get a count
    of the turns - it'll be instructive.

    And it's doubtful that anything but an exact replacement would do
    the job anyway.

    And look at the bright side - you get those two ultra-cool
    magnets!

    Cheers!

    ....are they *really* attractive?

    For the cost of the replacment HV transformer you could probably be a long
    ways to purchasing a new replacment oven. Also if you do wnat to actually
    repair your oven you will want to check out the other items within,
    inclusive of the HV diode, Capacitor, Magnatron, and controller. Hopefully
    you do understant the safety issues in working on these items. BTW the
    Samsung transformers, in other applicatons such as the Sansumg Branded
    Ovens, have been having a "higher than normal" failure rate. Probably due to
    poor design or heat transfer.

    For the cost of the replacment HV transformer you could probably be a long
    Thanks for your posting. I have found a website that I can get the
    transformer for $119, but it will have to be back ordered. I'll
    probably have to order that on Monday. I have already removed the old
    transformer and it is obviously fried. As for the other components,
    any ideas on how to test them? I just don't want to spend the money
    on a new transformer and have the new one blow up. As for the dangers
    of working on the microwave myself, I read on the internet on how to
    discharge the capacitor, but the capacitor has ceramic insulators over
    the capacitor terminals so I could not short them together. I just
    waited for an hour after I unplugged the microwave before I removed
    the transformer.

    Resistive check on both the diode and capacitor. Discharge the cap first!!
    Check terminals of Magnatron, should check low resistance across terminals
    but infinate from terminal to case ground. Check also the thermal cutout
    since the transformer did seem to everheat. Be careful! Current withen these
    items has been lethal.

    Well, don't start investing in transformers just to use them for
    your diagnosis of what blows up the transformer.

    Good Luck!

    A brand new GE microwave can be had for a lot less money. I bought
    a small one for $49 a while back and its big brother for about
    $89. Both have powered turntables built in.

    At one point I repaired an earlier unit with a blown high
    voltage diode. The (universal) replacement was about $5.
    It didn't last very long.

    Microwave ovens are throw away units.

    Heck, if you ask around a little, somebody might _give_ you one!

    The capacitor or the maggie might also be bad.

    It is the *VOLTAGE* that is lethal!!!!!!!!!!!!!!

    Is this one close enough?

    The plate voltage and wattage is what you need to match
    This one costs $15 plus $10 shipping, and is 2100 volts, for a 1000 watt
    oven, and is a Samsung... it's on eBay, and there are others -

    No, sleepy, this is a consequence of lifetime limitations imposed during
    manufacturing and artificially high replacement parts costs.

    It has absolutely nothing to do w/ America, class, or mentality, but is
    strictly a consequence of capitalism.

    This one was real close, but not exactly. I found one just like the
    one I needed at this website for $14.95! I knew I could find one out
    there for less! Thanks for the tip!!

    Quite the convrese, sweetie.

    Price gouging at the consumer level is imposed in order to discourage or
    outright foil the repair industry. It is called "planned obsolescense".
    Quite the convrese.

    This capitalism pivots on our 'throw-away' mentality.
    Supply and demand go hand in hand, until there's either surplus or shortage.
    In the case of labor sent overseas, there is more headroom for
    mass-production of a surplus of junk. The market is flooded. No longer does
    anyone want "high end" products, because consumer grade is more 'economical'
    and 'frugal'. Then, the visious cycle begins again -- throw it away,
    because it is 'uneconomical to repair'.

    Therefore, capitalism is a direct result, of, among other things, of a
    nation's sloth and greed. It's cheaper/easier to just shitcan it...


    The trouble with this picture is, the lower income people are sucked into the
    cycle (no pun intended). The irony is, they are the ones who are forced to
    recycle, out of necessity, as opposed to greed.
