Not much information via search, but it seems as though there is usually
an adjustment screw somewhere behind the temperature control button.
Anyone adjusted an electric oven this way?
How reliable are the mechanical oven thermometers?
Top oven (Bosch combi) seems to register about 10 degrees lower than the
setting on the knob.
It should average out at approximately the set temperature, but
domestic oven is hardly a precision device. Most who cook keep in mind
that their oven under or over cook at a set temperature and make some
allowance for it, either on the dial or the time.
Maybe he means that when you set the oven temp
to say 200C, it actually runs the oven at 190C tho.
Not really enough of an error to matter, you'll
get that much variation within the oven.
Even less significant if its F instead of C.
As it happened I salvaged one last week but I CBA to unthread the pile
so I cut the capillary tube.
I can't see any adjustment screw...
...Just dismantled it further and there is nothing to adjust. The
capillary tube enters the centre of what is best described as a
bi-metallic labyrinth with a plastic peg that presses against the
Ovens don't have just one temperature.
The air temperature will vary inside (unless a fan oven), and the
radiant heat will also vary in different places depending on the
exposure to oven walls and their temperature distribution.
I wouldn't worry about 10C. Just allow for it when using the
oven. You might find it's not constant anyway and as more of
the oven heats up, it vanishes or even goes the other way.

Just get an oven thermometer and set the oven temperature dial to give
the reading you want on the thermometer. We have a Salter
http://tinyurl.com/jglybtq Seems OK. But as others have said, heat
transfer is almost all by convection at normal oven temperatures, so
unless you have a fan oven, temperatures will vary from top to bottom.
That's why some recipes stipulate placing the item being cooked* on
the top shelf or the bottom shelf, depending on what the item is.
*initially typed as coked! Freudian slip there, the difference between
my cooking and SWIMBO's :-) She cooks, I coke. Alfred's cakes weren't
a patch on mine for burntness.
