Purchased 1 month ago. The cost is lower than my last machine, and it makes ice at a faster rate. When I first turned it on, the air temperature was 107, normal for our area, it turned off, said High temp. I restarted, and it ran for maybe one week, never had any problem. It makes a lot of ice. In the middle of a day that was 117 degrees, again normal in our area, I turned it on, it read 15c, and turned off. Said High Heat. I re-started, it went down to 11c, turned off again. I started for the 3rd time, it ran, did not turn off, makes ice until you shut it down. The machine needs good ventilation in temperatures such as ours. If you start it in the morning, when temps are below 102, you will not have any problem. One trick I use if I start it in the middle of a hot day, is dump a sack of stored Ice into it, seems to lower the read out a bit. If you restart a couple of times, it will take off. The machine is insulated a bit better than our last ice maker, the ice lasts longer once we shut it off. We have an employee who likes the ice, he eats ice, says the cubes are easy to chew. Thanks, w
