My new Dometic portable ice maker has yet to make any ice and now does not even turn on. Are there fuses somewhere or a reset switch? Initially, I could hear it running and putting out heat but even after several hours, no ice was made. Eventually it did make a small amount of ice (maybe one rotation) but now it does not even turn on. Unless you have an idea of what I can try, I will return it to camping world for a replacement. Thank you
