Product review (2 stars): Kitchenaid Door Balance Kit from Amazon
The kit shipped from Seneca River Trading, Inc. and when it arrived I noticed the cords were about 1 1/2" shorter than the original one that had not broken. I decided to try the replacement cord and pulley on the side that had broken. I found that stretching the spring the extra 1 1/2" increased the tension so much that the pulley would not turn smoothly and made a very loud noise. I replaced the pulley with the original fixed guide and the noise was eliminated so I decided to replace just the cord on the other side and hope for the best.  The best lasted two weeks when both sides let loose. I wrote to Seneca River Trading, Inc. twice with no response and finally contacted Amazon. My credit card has been credited with the transaction and now I am looking for a supplier who handles a kit with chords that meet the manufactures specs. Seneca River Trading, Inc. did a great job of shipping out the order and a lousy job of customer relations.
