Hello all,
I have a bit of a problem and am hoping that someone here can help. I have a Mitsubishi mini split unit (MSZ-FE12NA) that was installed three months ago. It has worked beautifully up until very recently, keeping up with high outside temperatures/humidity with no problems. Recently, however, we came home to find that the indoor unit was spewing water out of the air exhaust.
We have checked everything we can think to check and have scoured the internet with no luck. The drain line is clear and is draining well (it emits a steady dripping stream of water); we used 1.5" PVC for the drain. The drain is sloped properly with no possibility for entrapment of water. No water builds up in the pan-- we are able to dump water into the pan and have it drain with no problems. We have also ruled out the possibility of back pressure in the drain. We are just at a loss, and tech support seems only to want to suggest that we make sure the drain is not clogged-- which we have done.
Our tentative guess as to the problem is this: There are coils along the wall side of the indoor unit; the condensate drips from them into the back pan, and then drips into the main pan that leads to the drain. For some reason, it seems that while some of the water follows this path, some of it does not, and instead ends up getting sucked into the squirrel cage/blower and out of the air exhaust.
The unit is spotless and always has the cover on. The filters are kept clean, and there is no lint or dust on the inside or outside of the unit. If anyone has any idea as to what the problem could be, we would appreciate any and all input.
Thank you!
