The picture with the chipboard shows that the chipboard does not overlap the support on the right side. This caused the refrigerator to bounce every time we hit even a small bump. The chipboard was not fasten to any of the supports. There were no supports going to the floor to help support and two of the screws on the left side were stripped providing little support. There is no way this would be adequate to support the refrigerator empty let alone loaded.
The next picture shows the new center supports across the width of the cabinet also the supports across the corners. The new plywood bottom fits to all sides of the cabinet, it is also held in place with screws.
Two of the four anchors in the sides of the refrigerator were damaged. I tried to repair them by filling the void between the inner plastic and metal side with a mixture of fiberglass and resin. My hope is it holds, if not we will probably have to replace the refrigerator. If anyone tries the resin/fiberglass repair make sure the void is completely filled and when the hole is drilled back out take it slow. This resulted in some loss of gloss around the hole inside the refrigerator.
