Product review (5 stars): Simply stops ice buildup
Installed unit into a yr 2000 build Kenmore refrigerator. eight  months ago. For the 1st time in years, I have not had to defrost to open frozen condensate to evaporator pan drain pipe, located below freezer coils. When clogged w/ice, water drips and collected under veggie draws then overflow out front door. Changing towels until I had to shut fridge off, store food in coolers, remove plastic tray in freezer and wait until thaw. Heat probe solved it for me. Maybe two minute install has save me much grief. Fridge still works well, quite. Don't see reason to replace the refrigerator anytime soon.
