I had the water filter holder replaced to fix the problem with the water for the door and the ice maker. The holder did not come with the cover for the release button for the filter. I ordered a replacement cover (Button) for the filter release. The cover fits over the release lever and was easily snapped onto the lever. It took more time to unpack the button from the packaging then it did to install it onto the filter housing. I don't understand why this part wasn't included with the new water filter housing.
