Jenn Air Duel Fuel Range, electric ovens having issues.

Model number JDR8895AAS

Good range, but ovens only work about 90% of the time. Gas stovetop, electric ovens. I think it needs a new computer control board for oven (possibly replace once before). It works most of the time but sometimes it doesn't heat up all the way.

Is there possibly another reason for this, or do I just need to replace the board now and then?
