The correct replacement shroud for your Dometic Duo-Therm 600315.321 (Looks like you added an extra 3 at the beginning which is what was likely causing your search issues) is the Replacement Shroud # AT3308046006 you were looking at.

Hello, I am also trying to replace the interior and exterior components of the same air conditioning unit. Do you know if there is a part for the interior that can be replaced? Or would I need to replace the entire air-conditioning unit?

@Anna Hey Anna. When you say interior components are you referring to the air distribution box? Or actually something internally in the air conditioner if you were to take the cover off? Let me know and I can see what we have for you.

@NickS Yes, the air distribution box is cracked so I'm hoping to find a replacement. I didn't find anything online, only that it has been discontinued. Do you know any other way to acquire this? Thanks for your help.

@Anna For an exact replacement for that I would recommend giving Dometic a call. We do not carry their units and AC manufacturers are no longer cross compatible. Dometic would possibly be able to get you a replacement distribution box for your unit. We would only have replacements for the whole AC system. We do still have the shroud for you thoug # AT3308046006.
