Product review (5 stars): using a Johnson controller to convert a freezer to a refrigerator
The controller allowed me to convert a 7 cubic foot GE  Chest freezer to a refrigerator which is what I needed for our summer cottage. it is maintaining the proper temperature to run the refrigerator.  It is being used on an off grid solar system. It has been in use for a couple of months and so far we are pleased with the results.
