Have duo therm rv ac on roof of my camper.
Rv roof mount air unit leaks int coach.
There are no drain lines for the ac unit on the roof of the rv.
One of the most common causes of the water leaking from air conditioner in rv is drain pan not able to drain the water properly.
Next inside the rv install the bolts that will hold the ceiling part of the air conditioner in place.
Another common culprit of leaking from the air conditioner into your rv is a clogged drain pan.
It s best not to walk on an rv roof rather use boards to distribute your weight.
This can be a result of debris or dirty on evaporator coils or due to blocking of the drain holes due to dirt or due to purposely done sealing.
To check for this situation again disconnect yourself from power and carefully ascend to the roof.
Which ideally should drain the water from the evaporator coil on the roof instead of inside of the rv.
Roof mounted air conditioners are very heavy units.
Finally mount and secure the ceiling portion.
If the leak is both while raining and while running and the gasket is still thick enough and tight odds are there is some roof deterioration underneath the air conditioner as long as the roof isn t sagging causing water to puddle up around the air conditioner which can be checked by pulling a string across the roof from side to side.
Then screw the unit in with the mounting bolts at the locations you ve marked.
Check to make sure your model does not have a condensation hose that may be plugged.
The condensation drips down into a pan which has an outlet on the side of the base pan that lets the water run onto the roof.
You should be able to find the torque specs in the roof ac owner s manual however a good hand tightening should be good.
Sometimes the drain pan gets clogged with dirt leaves and other debris prohibiting the water from draining through the small hole in the pan and onto the roof.
It is quite common to find the roof area around the air conditioner sunken or sagging especially on those rvs with soft roof construction.
When i turned the unit on it begin leaking into the camper in the area of the filter.
Also you need to check the torque of the fastening bolts.
Model xxxxx ser xxxxx purchased with camper in 2002.
Condensation from the a c unit has been a long time battle with rv owners.
As mentioned above the drain pan has a small hole in it allowing the water to drip out.
What happens is water can start to collect.
Your roof ac unit is mounted with a gasket between the unit an the roof typically with 4 spring loaded fasteners that should be checked for specific torque or tightness every year.
There was a co read more.
Each rv roof top air conditioner has a gasket underneath between the ac unit and the roof and these can sometimes develop leaks even on fairly new rv s.
If it is leaking inside you most likely have a clogged outlet which can be easily opened with a stiff wire probed in the drain outlet.
However if the drain hole s get clogged with dirt leaves etc the water may roll into your coach even if the a c roof gasket is tight.
They are subject to all the vibration wind and the elements that occur during your ownership of the rv.
