Dometic refrigerator issue

[perm10]

I have a 2020 27FB. I was looking in the outside compartment of the refrigerator and found this part laying in the bottom. I contacted Dometic. They said it is from the top of the flue stack. Does anyone have an idea on how I can get this part back on.

If you can't reach it from the vent you will have to remove the fridge. Most likely it will need to be secured in place somehow or it will just fall off again. If the fridge is working fine I would put it in the drawer and forget about it till someday when the fridge gets pulled. The flue stack is packed with insulation and I don't see that little piece if tin doing much of anything but making it look nice.

I can not even see the top of the flue stack or reach my hand up to the top. I am glad to know I can just leave it off.
