A Rov advised that one can avoid Bishul Akum when using an oven by a Jew turning on the power even if the oven is off and the non-Jew then selecting the program and turning on the element. He compared this to Aish Me’Aish. I would welcome your opinion as I see a major difference between the two.
This does sound odd, and the comparison of eish me’eish is strained: a fire can cook, whereas an oven that is off cannot (even if the oven is ‘on’).
I don’t know who the Rov is, but without better sources it is hard to rely on this ruling.
