Air Conditioner Leaking inside Coach

Just this morning my front AC started leaking condensation inside my coach. Looking for help troubleshooting this. 2017 Miramar. Thoughts?

If you look under the hood, up and to the left, you will see the enclosure for the condenser. At the bottom of the box is a nipple that sticks down, it is the drain for the condenser. Buy some 1/2" ID tubing and attach it to the drain with a hose clamp, run the tubing down about 18" and secure with a zip tie. That should take care of your problem.

The leak is from the front roof mount air conditioner. Not the dash. Sorry I didn't make that clear.

Pul the cover and look up there will be either three or four bolts that attach the ac to the coach. Theer is a gasket that if the bolts are not tight enough than it will leak inside.

sorry, don't have an answer but this reminds me.... it happened to us one time while on our recent long trip. A good bit of water spilled onto the floor when I started driving one day. I was planning to open it up to double check
...was it a leaking roof gasket?
....was in a plugged condensate drain up on the roof?
....is something broken/rusted/leaking?
but then it never happened again
and never leaked in any of the many hard rains its seen since.... so i kinda forgot about it. Thanks for the reminder!

My guess in my case, the thing was sitting in some odd out of level state and the condensation built up somewhere that it normally does not.... one time thing, but still it's about time for me to take off the cowling and clean/inspect... tighten the mounting screws, etc...

Check for clogged drain

These units drains plug up and will then drip inside. Go on the roof and look closely at the A/C cover (shroud). About 2/3rd of the way back (from the front of the cover, where front is the edge closest to the front bumper of coach) look down for a tiny drain hole, or nipple. Likely will be black, so hard to spot. Take a pipe cleaner (or any small wire) and stick it through that nipple several inches. Do the same on the opposite side. Hopefully leak gone. Just had to do it on my coach. These leaks are usually clogged drains, loose bolts holding unit down so the seal is not tight, or a bad seal (gasket) between the roof and the A/C unit.
Good luck
Note: While you are on the roof, clear out the drains of your other A/C as well.

Good morning,

I have a 2016 Thor Tuscany 40ax xte, the front ac has leaked off and on since I took delivery in February this year, the mobile technician replaced the gasket, stopped for a while, then started leaking again, he came out and attempted to fix it again, not sure what he did as a neighbor was here, he stated that he fixed it, but last night it was leaking water from the rear area where the filter is, contacted the technician and he has no idea why it is leaking.

When I had my 5th wheel, the front a/c was a Penguin 13500 and not controlled by the main living area thermostat but had manual controls. If I ran it on max continuously, it would frost up and start dripping on the mattress. Solution was to run it a little less than max so that it cycled more often.

Also, if you are going to tighten bolts, don't get too aggressive with them and tighten them a little at a time going from corner to corner. Doubt that the gasket is your problem though.

Some time ago now, while in a campground I did pull the inner shroud to have a look. The mounting screws were loose....one was completely slack

So thanks again!

I take it you're saying pull the unit from the inside on the ceiling to uncover the bolts....big job or not? Tabs to pull maybe? I have a leak and would like to snug up the bolts but not sure I want to start tearing things apart unless I'm sure what I'm doing. Sounds like you have a handle on this.

Slide arms and rubber opening

Greetings all,

I have a question regarding the full kitchen slide, the living room and bathroom slide on a Tuscany 40AX Xte. I have light coming in on all slides, I noticed the opening where the arms go in have some major gapping, does anyone have an idea on how I can fix this or seal it while in place. I live in my coach full time, and being that it is extremely hot outside, warm air comes in through the bottom of the slide. Any recommendations would be greatly appreciated.

Also, has anyone experienced having to sync the slides all the time? the top piece of the facia near the mater bathroom slide has little clearance and has come off. I am trying to get the top piece from Thor, but have yet to hear back from them, once other thing, has anyone who has the theater seating with the cup holders experience any cracking? the front on of mine has cracked on the inside.

Maybe you should start your own thread with an Appropriate title rather than posting in a leaking air conditioner thread?

Arrrv.....I didn't see anything that looked like this....is there a pic of this anywhere online? Do you have to take off the shroud to see this?

I have a 2019 Aria 3901 and light pours in under the two large slides. I bought 10 large sponges and when we stop, I put these in the holes under the outside of the slides. When we break down, I make sure I remove them all. I am just trying to keep mice and other creatures out of the RV as we also are full timers and choose not to have gaping holes into our home.
