Product review (5 stars): Worked great but you really
Worked great but you really, really, really have to do a 24 hour defrost before installing this part.  I thought I could circumvent that with a shorter defrost but I did not melt all the ice that was blocking the drainage opening so I continued getting ice on the bottom of freezer.  I did the defrost and that did the trick.  I also got a pipecleaner and made sure the opening to the drain was not clogged by other material just to be safe.
