I have an older electric wall oven that when you set the temperature
on the dial, the oven will actually heat to a higher temperature. It
is very frustrating (I've burned a few dishes already). Any
Also, the knob broke off the "Bake, Broil, etc..." dial and I have no
idea where to find a replacement.
First, check that the ventilation pathway is open and clean. May be
as simple as that. If you take a cooking thermometer, you could also
see if there's a consistent offset and simply adjust your settings
appropriately. Do that w/ 50+ yr old "emergency-use" gas range here
as the occasional use of this makes it unprofitable to spend anything
on it...if it were primary oven, that would be different.
Second, could be it needs a new thermocouple. Depending on the age
and make/model, it may or may not be worth working on. Online places
have parts for almost anything even remotely common 20 years of age
and newer. If it's only the knob and not the shaft that's broken,
good chance of finding an replacement. For it, if can't find the
exact one online, take the one you have to a "full-service" appliance
outlet/service place and they can almost certainly find one that will
serve the purpose.
While I can't recall exact names or find a bookmark at the moment,
I've had good luck w/ two -- one was in Oklahoma City, the other in
Louisville, iirc. I'm sure there are many others. You find your
range model and serial number, go online to one of these sites and put
it in and it will give you list of any/all parts available.
Depends. Check with an oven thermometer to see if it's just
consistantly holding a different temperature than indicated.
If that's the case, glue a white label around the nob and
mark the true temperatures with a pen.
If it's NOT consistant about it, then there's something wrong
with the thermostat, and you'll probably have to start replacing
Many home appliances come with a label on them somewhere,
telling you useful things like, who made them, and what
model they are. If yours had a label like that,
you could look it up on the internet. Since it
obviously didn't or you'd have mentioned it in the
course of asking for help fixing it, I suppose you'll
have to make a new nob out of Bondo.
You left out the details. How long should the Bondo be left to dry? Can it
be used as is, or should it be given a coat of primer? Is it OK to hand
fuzzy dice from it?
Damn, I hate it when we only get half the story.
Or PC-70. Also very good. I'm assuming the shaft has a flat side or
flutes, and doesnt' depend on a set screw in the knob to fix it to the
Also, try an old tv store for knobs.
I found a beautiful big eletric rotisserie in a dumpster once. The
rest of it was full of building materials removed from some
renovation. But this was almost as clean as new, as clean as anyone
can get cooking stuff after it's been hot with food. I didn't know
how good rotisserie food can be. It was complete with trays and
grills and everything except knobs, that I got from my stash of tv
If it is old and uses a rotary dial to set the temperature then the dial
itself will often have a "calibration" feature built into it. This
usually takes the form of a couple of tiny screws on the back of the
knob (pull it straight off of the shaft) that allows you to rotate the
apron of the knob relative to the shaft. Place an accurate oven
thermometer in the oven, set the oven to 300-degrees (or some other
convenient temperature), determine what the difference between real and
set temperatures is, and then adjust the knob to match.
As for parts, I've had great luck with http://www.repairclinic.com/0070.asp
