Question
Hi For reasons beyond my control, I will be home for yom tov this year. I am currently renting, and do not have access to a stove or oven, and do all my cooking in rice cookers. They are permanently on a keep warm setting when plugged in, and to cook, I push the button down and when the food is ready or when I lift up the pot insert, it automatically pushes the button back up, moving it back onto a lower heat setting. Am I allowed to use them on yom tov to cook or warm up my food? I've never had this problem before, as I can keep everything on the keep warm setting over shabbat.
