F.H.
Just so happens I have FIVE crockpots and they are still on my counter waiting for hubby to put in the garage after Tgiving (I cook all my sides in them)...I looked on my Rival and it has this website and phone number for questions: crockpot.com and 800-557-4825. Mine has a "warm" setting and as far as I know, you have to manually switch it over, but you may have a newer version than me. Good luck!!!
