Product review (5 stars): Replacement for old Wards 17 cft Frostless Timer
Freezer was not defrosting and was icing up every week and would need to be defrosted.  This timer seems to have solved the problem.  Screw holes fit exactly.  Be sure to check the wiring ground when installing; I had to move one jumper; ground from old time was rivet which needed to be drilled out so was not exactly plug-and-play.
