    Hello all,
    This toaster oven is about ten years old. It was not reaching
    temperature so I replaced the mechanical thermostat with the proper
    replacement part from Philips. The old thermostat had totally worn
    away contacts. I figured this altered the travel of the bimetallic
    strip. There is no adjustment for this.
    The new thermostat chatters a lot. When the bimetallic strip heats up,
    the contact doesn't make a clean break, and it doesn't do a clean
    make. It also doesn't seem to be linear, either the oven is too cool,
    or too hot. There is a lot of sparking in the thermostat.
    What can be the problem? The heat path seems fine, there is a
    probe-type assembly that holds the thermostat by the core and I
    cleaned it.
    Is there some sort of secret to getting these mechanical thermostats
    to work properly?

    Worst case, what toaster ovens do you technically-minded folk
    recommend? There seems to be more and more fully electronic controlled
    ovens out there, are they debugged? Which brands are good? I'm not
    interested in mechanically controlled ovens anymore, I get the feeling
    the quality is not there anymore.
    Thanks in advance.

    I buy the $20 ones from Wal-Mart. Work fine, and if it craps out you toss
    it. I've had bad luck with electronics for this sort of thing.

    The heating elements also have to be replaced, and this is why the
    thermostat was most likely damaged.

    Why would anyone want to put money in to fixing an old toaster oven???

    You can buy a very good cheap one these days. Or, you can spend a few
    dollars and get a very good one. They generally will last about 4 to 10
    years, depending on the frequency of use, and how it is used.

    These are all considered throw-away type appliances.

  4. Why do you think the heating elements need to be replaced?
