Sara for Model Number FRS6R5ESBN AP3867199 is the middle shelf and the AP3867216 is the upper shelf. My freezer has two unused shelf areas under each of these two shelves so I am unsure which to order or should I order both. I just want to add extra space to the freezer by ordering two shelves.

Order the shelf that fits properly. Hope this helps you, thanks! Read More... Answered by AppliancePartsPros.com | Thursday, May 24, 2012
