I have never had issues with crock pots turning on and off. We use them every weekend for special events indoors and out, summer, winter, spring and fall. I work for a fast food chain, and we do chairity events..and we sell food from them and all the money goes to the event holder. We have to take temps of every item we use there..and if it is not up to temp..guess the Mr Garbage eats well. It has never happened to us in the 9 years I have been doing this. We cook or keep hot..chicken, beef and ham.
