Dometic Roof Air Question
I have a 2001 Vantare conversion with 4 Dometic Duothem roof airs. On one unit I am getting either condensate dripping from the return or it is condensation from a leaking cold air supply. It take 30 -40 minutes of run time for the unit to drip water and it is a very small amount.
I have looked through the installation book for these units and there is no mention of a condensate pan to collect the water so it can drain under the coach. Is this something Vantare would have installed and if so, does anyone have a photo or description of such.
I suspect it would easier to go up on the roof and determine if the leak is there. There is plenty of condensate comming from the drain so I don’t think I have any blockage.
The other option is condensation building up in the cold air distribution system which then leaks into the return. I hope that is not the issue as I guess that would require a lot of work to get at the duct work.
Any advice would be appreciated.

There should be a hose connection at the A/C unit that directs the condensation water down under the bus. I would check that connection and see if there may be a crack in the hose or it’s lose allowing some water to drip inside. Also check for leaves and junk that may be partially blocking the tube. I have also blown compressed air in the drain hose from down below that will purge any junk that may be blocking the tube, but you still have to get up there and check it out.

I just purchased a 2001 vantare and had the same thing happen on my front unit. I took it back to the dealer and he said he did not find any issue and in fact ever since I have not had it re-occur. I never found out why it happened. I don’t know if they found something and did not say or if it was just some temporary blockage. My units all drain out the bottom of the coach through a vent tube. I’m going with the idea that there was some sort of temporary blockage or restriction of the vent that cleared.
