Product review (5 stars): The new unit works fine. The first few hours were questionable
Three years ago I installed one of these and it recently failed.  The adjustment screw on the side slipped and the freezing tray overfilled.  This could have been from me stuffing  the freezing compartment with non ice items.  The new unit works fine.  The first few hours were questionable. I had turned off the refrigerator while working on the installation.  Yes, it will not make ice until the refrigerator is turned on.
