Refigerator/freezer was not cooling

I first removed the freezer shelf, then the back internal freezer wall by removing the 4 screws with my nut driver. Then removed the fan cover, by releasing the clips (6). Then unscrewed the fan mounting brackets (same nut driver), then released the fan. The connector on the replacement fan was different to the original, so I cut both connectors off, and reattached the 2 wires with wire nuts.
I then reassembled everything, and all is well. The refrigerator was successfully repaired
