I have a chest freezer that I have turned into a keezer, and it has been having issues lately. After it stopped working a few times, I finally figured out there is a knob that spins around kind of like the timing knob on a dishwasher or clothes washing machine, and if I give it a twist the freezer will kick back on. I'm am having to do this every few days now, and was wondering if anyone has any ideas, or has dealt with this before.
