General Electric (Toshiba) JP392R Magnetic Induction Cooktop

  1. My Mom has a General Electric (Toshiba) JP392R Magnetic Induction
    Cooktop. One of the induction "burners" has failed. The replacement part
    is a WB27X5492 which is a pricy and apparently unavailable module
    containing two "burners". GE holds the warranty and says all they will
    offer is a conventional cooktop as a replacement. This is not acceptable
    to Mom who has had threee of these units over the years and loves them.

    Can anyone advise how to obtain replacement parts? Schematics? What is
    the common failure? Can right and left modules be exchanged if one finds
    a module for the "wrong side"?

    Thanks in advance!

    The only hit on Google for that part number says it is an "ICT RH Inverter
    Module". The hit is at a site http://www.pcbr.biz/ that claims to rebuild
    NLA appliance control boards, timers, etc. Their price list doesn't include
    that part number, but you may want to get in touch with them. If you
    haven't already, you might also try asking parts distributors, such as
    Marcone, for price and availability on that part number.

    Looking up that model number at http://www.partselect.com/ yields a $730
    "power module" which apparently contains two burners and most of the drive
    electronics. It also shows a couple of Kenmore cooktops that take the
    same part; maybe Sears has one in a warehouse somewhere.
    Who has pursued it with GE and how far? If only your mother has called,
    you might try calling. It's not supposed to be this way, but sometimes
    having a man call yields different results. If nothing else, ask for a
    top-of-the-line Profile conventional cooktop, then sell it and use the
    funds to buy an induction cooktop from someone else.
    Just be one out of maybe a dozen people in the world at Toshiba and/or
    GE that would have access to this info. Otherwise, forget it.
    I don't know for sure, but it should be relatively easy to test for
    things like an open induction coil. I think the major parts of each
    burner module would be the induction coil, one or more beefy
    transistor(s) to switch the power to the coil, a power supply, and the
    driver circuitry for the transistor(s). Since you have a working
    module, it should be possible to compare voltages and waveforms back and
    forth to narrow it down a little.
    I don't know, but I suspect that if it was listed as two different part
    numbers, the difference is non-trivial.

    Standard disclaimers apply; I don't get money from any of the companies
    mentioned.

    I got one of these tops kicking around. I'm not going to use it.

    We should compare notes, if parts will fit, great, if not maybe I'll
    sell you the whole thing.

    Could you tell me what you have on hand? Model numbers, Condition etc?
    Also where are you located?

    Thanks Joe

    I have the same unit and need a replacment element, large size also. I
    have tried to contact GE with the model number to get parts but to no
    avail. I could also use all new touch pad surfaces Any help ??
