the original problem was that bake on this unit did not work, i found that the bake element did not have continuity replaced the bake element and the unit worked properly for about 2 months. then it wouldn't heat again so but the element was still good, so i replaced the board and the unit heats now but wont cycle off when in bake mode. i read another review that was similar and he said he replaced sensor so i am assuming he means the temp probe, but he said he had no luck with that so i don't want to try that and waste the time and money without confirmation. so any other ideas, or do u think the temp prob is my problem. thank you very much for the help.
