Product review (5 stars): Works like a charm!
My fianc disposed of two refrigerators he had kept in his garage because they had stopped working when it got cold.  I mentioned to him that I had read that refrigerators stopped because, with the cold outside, the refrigerator sensed adequate cold and powered down so that the freezer stopped freezing.  We bought this kit and it works great.  The refrigerator in the garage kept working through freezing temperatures all winter.
