No instructions came with the part. Air conditioner repair man in the house when parcel arrived. He tried to fit it but found it frustratingly hard but succeeded in the end.
I opened both fridge doors and with the crisper tray in place found the small slots at the top corners of the top of the crisper. I positioned one corner of the crisper lid so the corresponding small round knob on the lid to sit in the left side slot and then gently pressed the knob on the other side inwards to fit into the other slot.
Removed crisper bin. Inserted new lid by slotting in the right side hole first then sliding in the left side into the hole. The centre wall flexed enough to allow the installation. I had to partly pull forward the shelf to insert the bin into place then push the shelf back into place.
The part I ordered was not identical to the original even though the model and make of the fridge were correct. I needed to shave approximately 5 mm from the upper side of the rear corner of the clip so that it cleared the lower edge of shroud over the upper hinge. I then fitted the clip to the upper side of the door using the single screw.
