Hi there everyone, i need a definite yes or no as my Rabbi cannot paskan either way even after consulting with the Beis Din, my kasher is as follows,

i have an old fashioned microwave oven with just to dials on it, one for time and the other for heat, i stress dials as this is important, there are no lights either outside or inside and no digital things whatsoever, if on friday i turn the dial for time on full for say 59 minutes and the heat dial to heat as opposed to cook and then connect the oven to a time switch so say on shabbos morning it is set to come on at 12 55 for 7 minutes and then go off so there is no power connected to it, and the meal is already cooked so the oven is merely heating it, is that ok, especially if i put a sign on the oven door saying "shabbos" i really would like an answer as i have already said, my rabbi cannot say no but also cant say yes even after consultation thanking you gerald silverstein
