Found the parts that hold the ice maker thermistor in the tray a month ago. Got the parts and was easy fix but the refrigerator stopped working entirely about the same time. Diagnostic mode wouldn't work and both temperature read outs displayed 32°F. Spoke with Tyler at Appliance Pros & he recommended Main Board replacement and provided part number. Checked this and price online. Confirmed part # and found that APP had the lowest price. Got part, changed, and life is good! Spent under $400.00 for icemaker, board, & misc. Better than $1,800.00 for replacement.
