Most of the time it is one of the heating elements or both. It is also
possible that one side of the voltage to one of the elements is missing.
When the oven starts, both the upper and lower work together until the oven
is up to near the proper temperature. Then when in the bake mode, only the
bottom one should be working.
I would try the both elements together, since it is an old unit. See if the
parts dealer will let you return them, if you find you want to scrap the
stove. But, if the stove is working correctly, it will be about as good as a
new one, except for the new fancy options.
An oven is basically a simple hot box, and a base electrical system. Once
the elements are operating correctly, and the thermostat works, there will
be very little difference between an old unit, and a new one.

A friend of mine has an old oven that is taking about an hour to heat up to
the proper temperature. Before they shell out for a new range, is there
something that a repair novice can check and service?
Thanks.
