Every time my oven heats up or, if I use 2 burners at once, the circuit breaker pops. I have already replaced the circuit breaker so I know it is not that. There is also a spark that you can see behind the control of the range when it pops the breaker. The range is 8 years old. I don't know if I would be better off buying a new one or if there is something I can do to fix this one. Any help would be greatly appreciated.

Here is a service manual which should come in handy

You have to join the site to download the manual but it is free and this is a very good site for manuals and other info for the appliance repair DIYer.

Unplug the unit and open up the control panel.
Since you are seeing a spark there should be some evidence left as to where the problem is.

8 years is an awful short lifetime for a stove and it may be an easy fix.
