The Rishon who this comes from is not Mechalek
We don’t pasken like him.
Also, the Jew helped by making the Chulent and putting it in the crockpot.
That’s not one of the actions which prevents it from being called bishul aku”m.
Please don’t bring Rayos from other things. It (crock pot) might be similar to a hot plate, but in No way is it similar to a microwave.
Let me clarify what I was addressing. Aside from the issur of havarah in turning on the crockpot, there’s also the issur of bishul – cooking the raw cholent. Even if the crockpot were not considered aish, it would be bishul.
Now, one might argue that if the crockpot were not aish (it is; I’m going l’shitoscho), there would be no bishul D’oraiso, similar to cooking in the sun (which is entirely mutar), or something heated by the sun (toldas hachamah which is assur m’d’rabanon). For this, I brought R’ Moshe’s teshuvah that cooking with a microwave is a D’oraiso, and so would be cooking in a crockpot, even if there were no aish.
