I noticed Ice maker Quit for the third time in 15 years so I decided to buy another Ice maker, I installed it and NO ice still?? Well I went after the other problem thinking if it does not get cold enough maybe ice maker won’t work. I ordered Defrost Switch, Heater and Evaporator Fan just to be safe. I replaced all three, the fan was noisy, the heater OHM’d ok but I replaced it as did the defrost switch, I put it back together, the Freezer got to 0 degrees and the frig got to 38 degrees so I figured it will make ice! Well no Ice??? I said all that’s left is the Optics Boards and the inlet valve both of which I replaced in the past. Well I replaced both of those and still NO Ice??? By this time I’m into it for near $700.00 and said there is NOTHING left to replace??? Well I called the store I got the ice maker from and told them can I exchange it? (APED) and they said yes they will exchange it for another new one. I was there and back in NO time, installed the newest ice maker and it Cycled and 35 minutes later I had ice finally. So, sometimes you can get a BAD NEW Part, though rare it happens. I needed the defrost switch, evaporator fan and Ice Maker. I did not need the inlet valves, heater and optics boards.
