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.
Rv roof ac drain off roof.
The moisture that is removed from inside the rv must be relocated to the roof of the rv where it usually evaporates.
On those types of days quite a bit of water may collect in the pan of the air conditioner.
There are no drain lines for the ac unit on the roof of the rv.
Turn off the air conditioner unit.
I would suggest taking off the exterior shroud and metal evaporator shield and cleaning the drip pan and checking the drain holes.
How to clean the drains on you rv roof air conditioner so it doesn t backup into your rv.
Typically a few screws or nuts hold it in place.
The fix is easy.
This moisture then drops down to the drip pan and is supposed to drain out the drain holes on both sides of the underside of the roof ac.
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.
The reason for this gap is that on most roof top a c units the condensation drains out the bottom of the unit between the base of the air conditioner and the roof.
At roof top level remove the shroud covering your a c unit.
Which ideally should drain the water from the evaporator coil on the roof instead of inside of the rv.
