Product review (4 stars): Perfect fit for our new Kenmore 18 cu ft
The instructions were a perfect match for our Kenmore frig.  Installation was easy. temperatures are now normal.  We live in NH where we have had some single digit night time temps.  Garage is running about 40F, if we keep the door closed.  I did not give this a five star, because I am expecting a larger electric bill.  Time will tell.
