B & C coffee maker heat fuse rating?

    I have a Black and Decker dcm2500 12 cup coffee maker that seems to need a
    new heat fuse. Perhaps I have the wrong name for it but it's in series
    between the pot warmer element and the heat sensor switch (wrong term
    again????). It looks like a common carbon resistor only made out of metal
    with a "pointy" end on it.

    The markings are so faded on it I can't tell what replacement part to buy.
    Could someone tell the number please?

    As an aside, why are there 2 of these "fuses" in series? Do they also
    provide some sort of resistance?

    Thanks in advance;

    Hi Al...

    It's called a thermal fuse; the markings on it would have
    been simply the temperature at which it would (hopefully)
    open.

    I'm prejudiced, I had a general electric coffee maker
    burst into flames on my kitchen counter once.
    No warning at all, nothing. Was downstairs,
    the smoke detector went off, I ran up and the
    plastic was in flames. A coupla more minutes and
    the cupboards above it would have been completely
    engulfed.

    So - given the potential risk to you and your
    family, and considering the cost of coffee makers
    now, I'd almost beg you to buy a new one instead.

    Take care.

    So do you think they put 2 thermal fuses in series just to be safe?

    Don't know. Good idea if it is :)

    Perhaps one is the fuse and the other the
    thermostat?

    You should read the rating on the fuse. Many of these are rated at about 105
    to about 140 deg Cels in these appliances. You need the correct one. This
    fuse cannot be soldered in. It has to be crimped in. You will need the crimp
    feeds or crimp loops (depending on the appliance connection type), and the
    tool to do this. You can do the crimps with a pliers, but it may not hold as
    well for contact, as when done with the proper crimp tool.

    I can tell you that if the thermo fuse blew, this is a sign that the heating
    element is having some problems. When changing it, the new one may not last
    long, or the heating element will go totally defective. I have seen these
    go opened, or go short and cause a fire if the thermo fuse does not blow.
    The replacement of the element with the delivery cost, will exceed the value
    of your coffee maker. Your appliance is not expensive to replace.

    As for coffee makers, you should investigate the opinion sites. You would
    be able to find a very good one. I myself have done very well with the
    Philips and Braun coffee makers over the years. From year to year both the
    models and the ratings change.
