The drains for that will be between the upper unit and the roof of the RV. You only have an inch or 2 to see under there so it's pretty hard sometimes, but you should see little round button like things sticking down from underside of the roof AC unit. They have holes in them, and can usually be unplugged with a stick, or piece of wire. If you can't get them cleaned out, you will have to make sure you shut breaker(power) off to unit, and remove the cover by taking out the 4 big Philips head screws. That will give you access to clean out holes in base of tray for drainage. If your getting dripping inside when unit not running but raining outside, then gasket will need to be changed.

Hi there, have a Hisense fridge model hr6tff526(s) which is leaking water from the inside,looks like its coming from the top where the fan is located.thx

Hi Kassem

It's probably just condensation water like what you get under an air conditioned car in the summer.

Usually in a Fridge they collect the condensed water and run it down a clear hose pipe to a plastic container at the bottom rear of a fridge.
This pipe can become blocked with food & junk & mould, mice etc.
Find one end and clear the obstruction. A flexible rod or wire or air burst.

RV AC is working fine, but the water is leaking from the ceiling Where is the drain tube on the unit, The AC unit is a roof type, Duo Therm serial # 43404934, Part # 3105459

Normally, the condensate will drain out of the unit onto the roof and off the edge to the ground. Remove your cover inside (probably 2 screws) and tighten the 4 bolts you will find inside. If they are tight, go to your RV supply place and get new roof gasket. Remove the AC and insert the new gasket and resecure the AC to your roof.

Thanks for your question @

Water Leaks inside of RV

When that happens it is because the drain hole up on the unit gets plugged with dust and will need to take a wire up top and run it back through the hole to clean the dirt out of the hole so the water can get out.

The Duo-Therm AC in the motorhome has started leaking from the inside after approx. 1/2 hour of use. What could be the problem?

More than likely water is pooling on top of the rv and leaking thru a crack next to the unit. The other problem would be the drain hole is plugged you will have to remove the top to ck. good luck

My 1990 Penguin unit has a leak. Can it be fixed?

Leaks can be repaired, some quite easily and others while difficult to find - and get to - prove somewhat more difficult.

The problem with 'leaks' is sometimes they are 'high pressure leaks' which are some of the more difficult ones to find.

So... the answer to your question is yes - but.

I would try and get a very experienced Service Tech to fix the leak, and one who will stand behind his work.

good luck!

I have a 1990 rv and the air condition is leaking

You need to find the evaporator coil on the a/c. This is the coil on the inside of the unit not the one on the roof. This coil will be sitting in a pan. This pan is the condensate drain and in one area there will be a drainage tube this tube is blocked. It will not be easy since the a/c is so compact however, if you contact an r/v dealer he will be able to tell you where the drain hose comes out of the r/v and once you find where the drain hose comes out of the r/v you can use a wet dry vacuum to create suction and remove the clog.

Good luck hope this helped

Rv ac unit leaks, even when fan only

Where the pipes enter the building, look carefully there for a bad seal. Use a good quality sealant and block the leak properly. If there is no rain, and the unit is leaking still with the fan on only, then you have an issue with the drain pipe angle or a kinked pipe or a blockage. Suggest you have it seen to by a aircon. technician as that repair is really not easy.(AC will possibly have to come out to rectify problem).
