Product review (5 stars): Save money, do it yourself.
My fridge was making noises that sounded like we had a woodpecker living inside of it.  After paying 8 bucks to have someone come out and diagnose it, the same company gave me a repair cost of $385 to fix the damper.  Luckily I watched the tech like a hawk and saw how he took it apart.  It was 3 screws...took him less than 5 minutes to do.  So instead, I bought this on amazon, popped the old one out, put the new one in...I had a little difficulty getting the assembly back together because of the way the left hand screw doesnt want to line up properly, but with an additional 10 minutes of jiggling it around, I got it in.  Sound gone.  Fridge works perfectly...no more freaky woodpecker noise.

I highly recommend this product.
