Refrigerator to warm freezer ok

The comments from customers experiences gave me the confidence that the defrost timer was the problem since the compressor was still working and it went just as they all said, four 1/4' hex head screws and I had access to the old timer, unplugged the old ,plugged in the new and put the four screws back in. Nothing happened so after a while I looked a bit harder at the accessable part of the timer after intallation and saw what looked like a dial. I turned the dialclockwise and immediatly the compressor turned on. I have not found any information as to how much or little to turn this dial which obviously is an adjustable cycle setting so I just turned it all the way, so far everything is working alright.
