How can I adjust oven temperature correctly I recently bought an oven but it was just yesterday that I saw that the knob for the temperature does not indicate any temperature. Only hi and lo. How can I adjust the temperature correctly?
It sounds like you need to buy an oven thermometer.  Put it on the same rack you'll be using for baking, and it will tell you what "hi," "lo," and in between (if available) settings really mean.
