So, I forget if about this time last year I posted on this subject as it happened to me back then once..
My wife and I were at Henderson Beach SP and it was humid...and the AC unit was not on...checked the thermostat, said if I recall E1 error....did a reset...and instead of showing zone 1 and 2, it showed Zone 1 and 4 OR sometimes after a reset it would show "Zone 4" but not allow you to do anything..the system was just locked...I was running on 30amp and on the single center AC, and because of the thermostat, I could not activate my 2nd AC at all.
Well, after fiddling for a while, checking the power at the pole, and a bunch of other crap, we left for some dinner and came back, and it then seemed to work without a problem...did not think much more about it since then (yeah, real smart).
Anyway, a couple weeks ago while down in grayton beach SP, this happens yet again...then I remembered the whole ordeal. And we had more people on this trip (we had loaded in the bunkhouse, me, wife, sister, my 2 kids ages 5 and 3, and two nieces ages 10 and 13...and it was 10pm when this happened
So, I get determined...upon reading on this forum, I ruled out a bunch of stuff, but found some talk about the "phone wire" that allows the communication and DC power to the thermostat...I checked the back of the thermostat, re-connected it, it looked fine..still had a problem...
Then I figured I needed to check the connection at the AC unit itself....and I remembered I have had this off and on issue with some condensation coming back from the AC unit from time to time when it is more warm and humid...
Took me like 20 min to find all the screws that hold the interior AC cover on (2 are 'hidden' behind those little flip out vents on the side)...then got it off, bunch of mosquitos came in when that came off like mad...then saw the problem...the phone wire is connected at one spot with a small sort of like junction box or a plastic cover over the connection, that little box was open and moisture was on it...also the points of connection have some mild corrosion....I uplugged, replugged, and took a small sharp pocket knife and scraped at the connections, re-connected...and all was well....whew.
Anyway, I guess at this point I will need to replace the phone wire connections (not sure how to do that, need to inspect it again)...and I need to figure out why the water is coming down...I saw a couple of the connections for the drain tube it looked ok...I need to get into that and figure things out...I read I need to block back from the drain lines under the wheel well...and is there like a drain pan up there I need to inspect?
Other posts seem to suggest that if you have a vent open or doors open and closed too much in heat, this will happen...I don't think that is my problem though as I have had that condensation come down when all was closed up tight...it notably happened historically when...you get up in the morning in summer, I keep the AC on with fan NOT on auto but on "HIGH" (I like the white noise and I know it helps prevent problems with freezing the coils when its hot out)...then I would cut off AC for a second and suddenly many drops of water trickle down onto the floor and side of the dinette under the AC...
So, I created this thread to
1) alert other owners in case they see this happen and
2) get any insights about my condensation/water issue
Also, hello, its been a while but I promise I am still around...going to port st joe memorial day weekend as well...hope everyone is well!
