Truma Aventa A/C drip

[Against The Wind]

Hello friends, have a situation that calls for your expert advice and knowledge. While camping at Stone Mountain Park near Atlanta this past week, we developed a drip from Truma a/c inside the cabin that we found disturbing. A slow drip from the knob that adjusts the front to rear airflow ( probably the low point) plagued us the last 3-4 days of our trip. Now, Atlanta in July is not the most hospitable place on the map with temps in the upper 90’s and humidity way above normal human levels, but after having factory service earlier this Spring, we figured all would be well. We were near level in our camping spot and very shady however,I did not see a lot of condensation dripping from our condensate hoses at the rear corners of the camper. I did notice some condensation running down the back of the camper so, does this point to a clogged drain hose? Is this something I can fix maybe by blowing air up the drain hose? Should I seek factory help? Should I stay outa Georgia in July? As always your knowledge and response is most coveted  Thanks in advance.

Interesting problem, but it sounds like you are on the right track. The volume of condensate coming from the hose at the rear of our trailer during hot/humid weather is high and starts almost immediately when starting up the AC. According to Truma it should be possible to clear a blocked condensate drain by getting up on the roof and clearing any debris (like leaves) blocking traps and the gap underneath the outdoor unit. Have you gotten up there to check things out?

Hello. I have a 2021 LE2 with a Truma Aventa retrofitted by the Florida Truma service center. I had a similar slow drip that developed from the air distributor. To repair it I removed air distributor from the ceiling. I found the Aventa condensation hose was spliced to the original Oliver condensation drain hose and secured with a radiator style hose clamp. That clamp was loose and leaking. A few turns of the screwdriver tighten the clamp and the leak stopped. I made note that if this leak reoccurs I'll find a more robust (maybe spring style) clamp to use. 

Regards,

Steve

That happened to me once.  I blew out the drip hoses.
