Product review (5 stars): Terrific Solution To A Problem
Had a problem with a refridgerator's freezer section turning off when the temperature got cold enough in the garage. Then the stored food would defrost and or melt.
Apparently , the fridge can't drop below certain temperatures for the freezer to work.
This Very Inexpensive gizmo , was easily installed and fixed the problem.
  I couldn't be happier with it.
