Product review (5 stars): After some troubleshooting have ice again!
I purchased this item from the reseller "DeepDiscountsco".  I initially had a problem with it where the shutoff arm would not return to the "on" position after creating each batch of ice, so it would not refill the ice bucket.  The seller did not have a solution, but was quick and courteous to reply, and willing to offer a replacement or full refund.  I did some experimenting though, and found that I had pressed the arm into the mechanism too tightly, and friction was keeping the relatively weak spring from returning it to the on position after each cycle.  Now that I have reinstalled the arm just lightly inserting it into the mechanism rather than pressing it in, it works fine.  The icemaker came with only two wiring harnesses, but I didn't end up using either of them.  I just used the old one already in the fridge.
