Furnace / fridge vent shroud or coveron roof

[Wantoride]

It’s been only 6 months or less since I checked the roof on my 2014 passport 23rb. Noticing roof issues I ordered a cover and finally got it on today. While putting it on I noticed the plastic cover over what I assume is a vent for either the fridge or furnace or both. The plastic cover literally fell apart while the cover was being installed. Am I correct that this might be a cover or shroud for the furnace/ fridge? Looking thru the broken pieces I see screen but did not remove the whole thing till I know If I can replace it. Is anyone familiar with this? I need to replace it but not sure of the description when I start searching online.
Thanks. Wantoride

Sounds like the fridge vent cover. You can get a generic one. There is 2 different lengths, and if I remember the Camco has two sets of indents for the screws. When you replace it, put some type of sealant on the screw heads.

That is the fridge vent cover. On mine, the grey tank vent pipe terminates under that cover as well. This is what mine looks like. It is a Dometic part #3311236.
