Exactly what I was asking! Although it seems that with the Lid on, that would bring the temp to OVER 150 degrees. My "newer" (as I have several Crock Pots) boils water High, guess I could always try it on "Low" temp, but I don't think Low will get up to 150 degrees, even with the Lid on!
But thank you! That answered my question!
I had the same issue - High will always increase the temperature until it tops out at the crockpots highest temp - Usually around 220F for mine.
LOW as well is above 150F for me.
WARM is what I use - With the lid on hangs around 147F
