I've just moved into a house with an AGA range
(http://www.aga-rayburn.co.uk/), and am having difficulty getting the
temperature right. Basically the lower oven is about 215F (not quite warm
enough for granola) and the top oven is about 400-450F. The plates on top
are however not that hot -- things take an age to come to the boil on the
boiling plate. The thermometer on the front suggests it is running a little
cool, but if I turn the knob on the side and wait 24 hours for it to warm
up, the lower oven ends up about 250F (just right for granola) but the top
oven ends up being 450-475F, which is too hot for most things.

Am I missing something, or is that Just The Way Things Are?

It's a 2-oven gas-fired model (possibly a Mk II), but it does have a
mysterious metal dial on the front, with numbers inlayed into it. It is
currently set at 3, for what that's worth. I've not been able to find any
information about what this dial does, nor indeed any pictures of other AGAs
with such a dial. I do wonder whether this dial might in some way influence
the apportioning of heat to the plates vs. the ovens...

Thanks,

Nick
