Product review (1 stars): Save yourself the time and money
Less than a year ago, I bought this part from another online retailer.  Experience much the same as many reviews on here - 1 1/2 inches too short, super noisy, etc.  I'm sure it is the same part Seneca River is selling.  Broke after a few weeks. Then they shipped me another one, same exact problems, and broke again.  Actually, I only replaced the broken side (one side still had working OEM part), so I did the repair a total of four times and it broke every time.  Finally, the last of the four broke, and I toughed it out until the OEM part broke on the other side. After all this time and effort, I decided to wise up and order directly from Whirlpool.  Sure it was twice as much money, but I figured most online stores are selling either a counterfeit part or an obsolete one.  Well, it came in the mail today, and the package says "FSP Appliance Care Products By Whirlpool Corporation" "Made in US", and "Genuine Whirlpool Quality".  The part was different than before (from OEM and my first-fourth knock off ones).  The end that attaches to the door is not bent in a slanted L shape, but is instead in a straight line exactly parallel to the cord.  I think this is because the old design put a lot of pressure at the L point.  The pulleys were made of clear plastic instead of opaque, and there are tiny manufacturers markings on the backside of the pulley assembly, where the knock off had none.  The cord was easier to get on for sure but still seemed a bit short (had to use vice grips to get it over the pulley, but in retrospect maybe it would have been easier to put the screw in after threading the rope through the pulleys instead of using the grips).  Unfortunately, I forgot to measure it before putting it on, but the parallel design likely compensates for any issues here.  And guess what?  No noise.  quiet as a mouse.  We'll have to see if it breaks again, but for now I'm very happy with the genuine part.
