Don H Fairhope , AL May 07, 2017 Ice maker only worked in test mode Talked with support rep who suggested replacing the master board. It was a stock item and shipped the same day. I received it by Fedex in two days. My paperwork indicated the repair would take 15 minutes, but I turned the power on in less than ten. The system now works like new. Thanks to your staff.
