Greetings all. Dumb question number 73 in a continuing series: The knob is missing off of the thermostat control on my 66 Caravel refrigerator. I just fired it up for the first time (it works!) since buying the Caravel. Do you turn the knob (were there one) CLOCKwise or COUNTER clockwise for maximum cool?
