Which way do I turn the dial to make it as cold as possible? The dial looks somewhat like this Warmer [9 8 7 6 5 4 3 2 1 Off] Colder When you turn towards the colder dial it shows [9] and when you turn it towards warmer it shows [1] or more drastically, [Off]. So it appears the 9 would be colder but I have no idea., Please help! My milk keeps going bad!!
