Thanks for this. In regard to the plastic nut in the fridge vent, I didn't use it, I sized the hole small and threaded the keeper in then used pvc glue to bond the 2 together. After all was done I dicored it as well. Should have just ripped the screen off and used the nut after I dropped the screwdriver through but didn't have any expanded mesh that was light enough to repair.
I don't understand why they put that screen on top under the cover when at the bottom of fridge a small bird could get in through the slots on the door????
