Got some water dripping out of the rear A/C main vent yesterday. It had rained the day before, but was not raining yesterday when the dripping was active, so I assumed it is probably a clogged evap drain / pan drip hole? Never cleared an evap drain, was hoping someone could tell me I'm looking in the right place. I still have the original Duo Therm Penguins, and I'm going up there this afternoon.
Take off shroud, then take off interior metal cover to get to the "second" interior evaporator. Then I want to find the holes and look for a clog in the pan under that evaporator, correct? Do I need to / will I be able to remove that second evaporator, or is that overkill? Anything else I need to unplug&clear?
Am I missing any other common draining issues?
Thanks.
Never had a drain stop up. Have you ever replaced the mounting gaskets on the AC,s? You might also remove the inside cover and check the mounting bolts for tight. Once you remove the covers you can see the gaskets.
James,
I had that same exact problem with the same Penguin unit. Solution is described in link below. PM me if you need any more details on my fix, which by the way, has been working for 2 years. No more showers on the bed! ^.^d
A/C Water Dripping On Bed - PROBLEM SOLVED (http://www.foreforums.com/index.php?topic=25235)
Maybe it's only dripping because of continual running, ice forming and then melting.
Sometimes in real humid conditions if running the fan on auto this can cause this to happen. Might try running the fan on low speed and see if that cures the issue.
We had the same issue. It maybe a combination of things. These were the things we checked/fixed, and haven't had the problem since.
1. clogged drain hole - make sure it isn't clogged
2. installed the "condensation kit" in both units
3. cracked drain pan (probably the biggest culprit) - both of our A/C units have cracked pans. To replace them, you have to take out the entire A/C unit. A MUCH simpler fix is to use caulk to redirect the drip flow away from the crack, and into the drainage hole.
After fixes #1 and #2, we still had dripping. Once we fixed issue #3, we have had zero dripping.
Good luck. You will feel like a STUD when you get this issue fixed. There was much rejoicing once we did. ^.^d
Rain every day over the last week kept me from investigating this until today. I tightened the mounting screws, but had no leaks during the rain this week, so this was more of a procedural thing. It seems everyone has a crack/hole in a slightly different spot, so I took some pictures, maybe it will help someone else who has to investigate.
First picture is just the interior evaporator. It has only two mounting screws, one that comes in from the left, through the electric panel, and one that comes in from the rear on the right side.
Second picture is the right side of the coils. I had to remove the metal panel on the right side as well to really see what was going on. Three small hex head screws.
Third picture is the bottom of those coils. Red arrow is the drain pain where the water pools. Green arrow is the drain canal where water flows onto the roof. Note this is NOT where Chuck/Jeannie had their issue. Their water was never even reaching the drain pan. Just to the left of this picture, the evaporator sits on an elevated surface - water runs off this surface into the drain pan. Their elevated surface was compromised - mine I think was still OK. It's a difficult surface to get access to.
Forth picture is where i had my issue. The arrow right where the drain pan met the drain itself. This is where water was flowing, eventually onto the large interior metal base on the unit.
I filled this area with some silicone sealant, and now I'll wait 24 hours, pour a cup of water through the drain pain, and hope it's my only crack!
