Product review (5 stars): Works fine and FAST delivery
Works perfectly and FAST delivery!  Easy to install. Freezer icing up and fridge warm. Repairman defrosted and cleaned out drain tube for $175 -- but that was not the problem. It was this little part!  Works fine now!

update May 2017.  These work but tend not to last.  I have ordered two others in the last 4 years, for a total of 3.  The first I replaced lasted 2 years; the second lasted 1-1/2 yr.  So I have ordered a third as a spare for when this one fails.  Easy to change and saves repair $.  Just wish they lasted longer.
