    Hi

    I'm new to this group but it looked like the right place to ask: I have an
    old sunbeam mixmaster that I'd like to bring back into service - no model
    number I can see but looks like this one http://fat.ly/juwy2 but with a
    black base.

    Everything seems fine except that the resistor that shunts (assume this is
    the correct term?) across the speed controller is burnt out. The blue
    plastic covering has cracked and flaked off and the resistance wire has
    broken near one end. From measurements (one end to where the break is),
    guesstimating to full length, I'm guessing around 700-800 ohm, give or
    take, and high power, but was wondering if anyone here might know the
    exact value and power rating? Even ballpark would help.

    I did try an 820ohm 5w I had lying around and it did work fine for a short
    period until the resistor died (smoked) and which point I shut it off
    (nothing else was even warm so here's hoping I didn't damage anything -
    guessing not if my understanding of how the speed controller works on
    these is correct).

    thanks in advance
    JM

    Thanks for the heads up. The grease doesn't look too bad. Maybe a little
    gritty on one side (the side where the juicer attachment goes). Still I
    guess it wouldn't hurt to clear it out and put on some clean grease.

    Thanks - seems my guesstimate was pretty close. Hopefully will have time
    to get it working fully next weekend.
