Non Jew oven/hot plate

Can I have a non Jew turn on the oven for me on a yomtov?
Or turn on the hot plate on Shabbat?
Thanks

What is I forgot to turn on my hot plate before Shabbat?
Can I get my non Jew neighbor to turn on for me?
גוי של שבת?

1 Yes, but keep in mind if it’s a food that would be bishul akum, thenmake sure you put the food on afterwards
2 No, unless you don’t have warm food for Shabbat, but you can’t put food directly on hot plate

Why, if it’s not bishul?
