Product review (5 stars): Simple solutions to complex problems
After 8 years the freezer in my side-by-side started to have an issue with the drain freezing over.  After hours of defrosting and making sure everything was clear and perfect, the drain would freeze over again after only a few days.  Doing a little research in blogs I came across this deviece and sure enough, Amazon carried it.  Super easy to install and all I installed was the probe.  I did not need the collar or the insulation.  It's been a few months since I installed it now and no more problems.
