Product review (4 stars): Slightly DIfferent But Works the Same
I have a Kenmore made by Whirlpool. This is labeled, Whirlpool Corporation Factory Certified Parts". They are not exactly the same parts, but close enough. The pulley parts are pretty much the same. The stringed parts are different at the end does not connect to the spring. Instead of an angled piece, it connects in the center (see photo, but mine is broken). The width of the arms are also quite a bit narrower, by about half.
As everyone has indicated here (and for the same parts under other listings) the length is shorter, which extends the springs longer. How far? Well I'll tell you.
Measurements of the spring coil.
Door Up: Original = 6 inch; This Part = 6.25 inch (12.5%)
Door Down: Original = 10.5 inch; This Part = 11 inch (5%)
So not that drastic since the door down is the worst case. It seems to be working fine. We'll revisit this for durability if anything goes wrong.
Still, four stars form not being an exact fit like it is supposed to be.
