Air Conditioner dripping water

Marteau · 09-09-2014, 12:41 PM

On the two past camping trips we have had water dripping out of the air conditioner on the inside of the camper ( 19 H). It starts dripping on the door side of the camper, coming out of the cold air return. It dripped out after a good while on the other side as well. This is not an occasional drip, I'm talking about a couple of gallons in a two day period. The weather conditions were 95 degrees and 85% humidity. It didn't do this last year. Could something be plugged up or maybe low on freon? Thanks

what year trailer?...Gasket maybe gone if older.

Evaporator and its tray are likely plugged. Take the shroud off...google the model and cleaning evap and get directions, check tray for cracks..easy

Could also be the unit wasn't tightened down correctly. There was a lot of that going around not long ago, units coming from the factory with the AC hold down bolts loose enough to wiggle with your finger.

It could also be a combination of things. It could be the drain is clogged, or it's too close to the roof and is blocked. Both of those are issues that have been addressed in this forum by various members.

It's a 2005 19H.

if you haven't done anything with it you should give it an overhaul. I would check the evaporator on the front after you remove the cover there will be another metal cover over the evap...remove it and inspect. If you see water overflowing the drip tray unplug it. If it is empty maybe it is cracked. Clean everything and inspect again. You should definitely change your gasket. Either get it in the shop or do it yourself.
Just be careful of the roof. I wouldn't use it till it is fixed

If it's a flat roof, check your drain. We had a 2007 17 EXPORT, and with the flat roof the drain hole gets plugged real easy. The same thing you are describing happened to us. Check your hold down bolts and gasket as others have said too.

You are not mentioning a lack of cold air, so my guess is like others, clogged drain hose

Husker Red · 09-16-2014, 01:05 PM

Where does the drain hose go on a 2007 19h? I'm pretty sure mine is just leaking onto the roof too. One more thing to fix...

Same happened to me. I removed the cover. Cleaned the crud out that was visible. Found the tiny pin hole the water drains down and got a little metal skewer and cleared the drain hole. All has been good since then!

My campers at the dealer now. I'll have an update when I get the results of their diagnosis on it.

This is what a hold down bolt will do all by its self from the factory. You can see the black gasket and it's even compressed at this corner and I had another corner that looked the same. I'm not saying this is your problem but it's one thing to check.

Same thing. Cleared out the drains. The drains aren't hoses, but simply holes on the bottom of the collection pan that drain out onto the roof. Like someone said, they are small and clog easily.

I had to take off the top covering, then the sheet metal cover over the coils. With a flashlight you can see inside and where the holes are on each side of the drain pan. Assuming your air conditioner is similar to mine in the 17C.

Marteau · 10-05-2014, 04:05 PM

Well, the verdict is in! They replaced the AC gasket and the thermostat. Repaired for 106.40 by the dealer. I thought that was reasonable.

Yesterday I spent on the roof cleaning the coils and drain pans on my ac’s.

Here are 5 pics : #1 is me with the drain pan partly out. ,# 2 is the stopped up drain on one end. # 3 is the pan after cleaning and drilling the drain holes larger, # 4 is putting it back together with the outside insulation mod. , # 5 is another shot of the outside insulation from another angle.

I used the instructions posted here earlier. The insulation was already installed last year. It was easy to remove by cutting the corners and re-taping when replacing. I also spent some time straightening bent fins.

I used Totally Awesome cut with some water. It suds a lot but I used directed pressure as the video showed. I also used a small brush gently with the fins. It was amazing how much crud came out.

The you tube video I watched was spot on with directions and tips. You can use your own cleaning supplies. Watch a couple of videos on your unit before jumping in but it really makes a difference.

On real humid nights my roof mount a/c would freeze over in the coils and would drip down right under the a/c unit...

Never did anything to it to stop this...

In my case however it only on those real humid night with the A/C running all night long...

I could pull down my bottom vent and see it frozen over at the coils... I think mine doing this is because the bottom area is not all that sealed up during the night like a house a/c install would be...

Your problem is different from what I was seeing h ere over night on ocassionally very humid night...

Take down the bottom part and do some good cleaning and make sure the four long bolts that holds the a/c on the roof is adjusted to pull down the 14 x 14 - inch gasket is depressed evenly about a 1/4-inch or so...

Pictorial showing the roof gasket...

My four bolts would work themselves loose going down bumpy roads... ALA I59 was one of those roads back then where the concrete sections were very uneven for 60 miles or so... Even the big tractor truck back then were running down the sides of the road in both directions doing their 60MPH runs haha... Sort of unnerving to be in the right lane of the Interstate bouncing up and down and get passed on the shoulder side by a big tractor trailer truck hehe...

On my unit I would always setup with the back side slightly lower than the right side where my patio awning is. This would help any A/C run off going to the back side of the roof area instead of running off on my awning...

ADDED NOTE - I'm just now reading the dealer got it fixed...

Another strange, unanswered note is on my 2 units, one had a foam gasket sealing the evaporator coil on top, the other had a metal plate. Both were factory installed units and both are 15k units?

Do you have a link with details on the "insulation mod"?
My X19H (same as the OP's TT) has started doing the same thing. I am planning on spending some time investigating this weekend, any additional information is much appreciated!
I had seen before that the drip pan was clogged, I have cleaned it and drilled larger holes, but I think it's doing it again.
