Kenmore 790.42003605 double wall oven

[Double Oven]

The wife has the above, the top oven started acting up pre covid, so she has been using the lower one. That has now started misbehaving. I have been given one chance to fix the issues, so I have purchased a new control board and a relay board.

Initial problem on the top oven was it started to go on/off when warming up, then it started on/off while cooking.

The lower oven just burnt a batch of cookies, stuck a thermometer in, it's reading 40 deg above set level. Changed the temp sensor for a new one, no difference.

My question is this, apparently the ovens have to be re calibrated after the replacement of the boards, I have the process for the single oven, is that applicable to the double unit?

PS: I do not have a license to drive this, at least that is what the wife tells me.
