The gasket retainer clip is used to hold the interior door panel and the door gasket to the exterior door panel. If the door gasket is not connected to the door panel or the refrigerator is not staying cool, one of the clips may have broken and will need to be replaced. The retainer clip is made of plastic, measures almost 1” long, and is sold individually. There is a retainer clip kit available with the quantity of 24. Use your model number to locate the kit or call us with your model number and we will be happy to help you. This is a genuine OEM part.
