This is incorrect. The Sabbath mode allows the oven to stay on for longer than it normally would, so the oven can be left on the entire Sabbath or holiday with food kept warm inside, as lighting a fire is prohibited, and cooking is prohibited on Sabbath (but not on holidays). In some senses it is a misnomer - it should really be called holiday mode, because that is when cooking is permitted but lighting a fire (without a preexisting flame) is not.

Wow. I was wrong. Being quite familiar with the Jewish laws and an ordained rabbi, I am quite confused by this https://products.geappliances.com/MarketingObjectRetrieval/D....

I suppose there may be some rabbi who permitted this, but I would love to hear the reasoning. This is definitely NOT what Sabbath mode usually is.

Edit: here is the rabbinic authority that worked with GE to develop the Sabbath mode. They explicitly state that adjusting temperature on the Sabbath is not allowed. Again, I don't know why that feature exists as it does not provide any benefit from a Jewish perspective. https://www.star-k.org/articles/articles/kosher-appliances/a...

Wrong. I have an oven like the one mentioned. The manual (which I have read) specifically mentions sabbath mode will delay for a random interval without user feedback before starting the oven.

Perhaps you are misunderstanding, and sabbath mode will turn the heating element on and off without regard for user input - i.e. opening and closing the door. That the manual is not clear is not a surprise, nor is it that someone completely unfamiliar with the Jewish Sabbath laws would misunderstand them.
