A:AnswerI don’t believe I got a printed manual, but there is one online. I searched and found this at manuals plus https://manuals.plus/insignia/insignia-portable-ice-maker-manual
A:AnswerIn my experience, ice makers not part of a refrigerator typically store ice in a bin, stop producing when the bin is full, then produce as the ice is either used or melts. The water from the melting ice is either drained or recycled. For our business, we had a large Prodigy ice maker (capable of producing around 150 pounds per day) which worked that way.
Ice makers in refrigerators are able to leverage the compressor in use already cooling the larger area (I think).
A:AnswerThe compressor only runs when the ice is actually being made. It shuts off during the emptying cycle, and comes back on when the freezing tray is full of water.
