No, because we have an old fashioned pilot light oven/range combination with no electronics at all, which allows the flame to be adjusted as needed on Yom Tov. Believe it or not, they are still made and the cost is about a third of what the “Shabat mode” oven/range combos cost. The only thing missing is a self-cleaning feature on the oven.
In any case I would ask my rav before taking any action after hearing about a kol koreh.
