Product review (5 stars): Fixed my 16 year old refrigerator!
I have a 16 year old Sears Kenmore refrigerator that quit making ice. Bought a refrigerator thermometer and found out the freezer was 40 degrees and the refrigerator was 60. Bought this line tap to check the pressure. I had a vacuum of 12 inches on the low side. Charged it up to 4psi and now the freezer is 6 degrees below zero and 35 in the refrigerator. This works great!
