Then I watched a few clips on YouTube, and one of the video's of Appliance Parts Pro was so helpful and explained fixing the problem with just changing the Cams on the fridge's door in a few minutes. They were offering the parts on their Website. I called in the morning and double checked with their professional operator and he offered me instead of buying only one cam for $4.99, to buy the whole kit for $14.99 which was a good buy and included 6 cams and the same shipping and handling.
My order arrived in 2 days and we were able to change the cam in just a few minuets, Thank you so much for the clear direction and fast delivery.
