Product review (5 stars): Easy to install...and works perfectly!
I paid a local / professional service company $100 to take apart the unit, ultimately telling me it was shot.  Discouraged, I did a bit of research and learned the issues may be caused by a faulty door switch.  I'm less than technically inclined, but decided I had nothing to lose.  I ordered this item from Amazon on Thursday and it arrived on Tuesday (pretty fast).  It was very easy to replace my old door switch with this one.  Most importantly, it worked!  So for $15, my fridge/freezer is back to working like new.  I just wish I would have tried it before paying a professional $100 just to hear I needed a new unit!
