Ice maker had a leak and was putting wter in ice tray

I simply removed 3 nut head screews and the old unit came off. I removed the ice level arm off the old unit and put on the new one. I removed the old wire harness and plugged into the new unit. I mounted the new unit, plugged it in and was done. I had ice in less than an hour. So simple my 11 year old could have done it without help.
