    I have a Presto "Grandpappy" deep fryer that died the other day;the thermal
    fuse is open.I can't read the markings on it.Can anyone suggest a suitable
    replacement? I believe the fryer runs at around 350-400degF.
    (there's a separate thermostat to control temp.)
    it's rated at 1500 watts. The heating element ohms OK.

    Here's a link to a Presto webpage where you can order a free
    instruction manual. Maybe it has a parts list.

    I've looked at the rupture point of fusible resistors before but not looked
    at a failed thermal fuse.
    Is it possible to place the remnants on a heated surface with temperature
    monitoring and see when the conductor melts again ?
    Failing that try low and gradually increase temp rating

    If the fryer has a US Patent number, then search for it here ...

    The latter requires free registration, but the documents are

    Throw it out. Fried food is bad for you, and is available on every
    streetcorner anyway. You don't need one at home.

    I didn't ask for your dumb opinion.

    Thus,you earn the "plonk". You waste people's time.(and oxygen)

    it's a one-use thermal protection cutoff fuse,and I found it's specs and a
    source for it. (240degC./[email protected])

    but thanks anyways!

    turns out the bimetal oil-temperature regulator switch contacts stuck and
    the cutoff did it's job.

    Mr. Yanik:

    Whereas you are undoubtedly correct about my potentially wasting your time,
    if you put it in perspective I (potentially) wasted a tiny, one might even
    say insignificant, portion of it. What I said is equally undoubtedly true,
    and if by some bizarre twist of fate you hadn't heard the news about the
    perils of deep-fried food, the time I wasted might pale in comparison to the
    years I added to your life.

    With absolutely no offense to you, I might suggest that you get a bit of a
    thicker skin. This is, after all, usenet. There are many many many
    moderated forums in which you might have asked your question... this is not
    one of them.

    I do periodically post useful information, but if you choose to blacklist me
    over an innocuous, non-offensive posting, that is of course your decision to
    make.

    Buck up, old boy!

    Dave

    As an aside, what I stated was neither an opinion nor dumb. It was
    statistically suported and factual.
