Inside the unit where the condenser fan is, there is a thing called a "slinger ring" this picks up moisture from the drain pan and splashes it on the condenser coil. If the unit is not level, this feature will not work. Is your unit level?
The vehicle is leveled by the use of a level each time so I don't feel that is the problem.
Well, the reason for no drain is the slinger ring blows the moisture from the evaporator onto the outdoor coil where it evaporates. The other source of high humidity is an oversized A/C where it can cool the space before it can dehumidify and leaving the fan on in the compressor off cycle will only evaporate the water on the indoor coil before it can drain off.
I think I understand your possible explanation of the problem. Having dealt with the Roadtrek company for several years I question that they would have installed the wrong size unit. I am still awaiting a correction of the problem. What do you suggest?
Either cylcle the fan with the compressor or reduce the btuh capacity.
I have also been in correspondence with Roadtrek to no avail. I am very disappointed there has not been a resolution to this moisture problem. Even though the Fedders guide advises not to install a drain in the pan what would happen if we did drain the water to the outside? I await your response.
I am not optimistic that there is a quick fix. the only means of removing moisurte is by compressor run time. To be clear, you are not conversing with anyone who represents Roadtrek, Fedders or any other company. We are independent technicians that offer technical support. With that said, I still maintain that a air conditioner must have accumulated run time to reduce moisture. Short cycles do not accomplish this and after a short cycle, about everything that is left in the coil is returned to the air. The long cycles allow the moisture to be evaporated on the condenser coil and cast outside.
A drain pan will do nothing for you.
I am disappointed that I feel there has not been a resolution to the moisture problem. However I do appreciate your prompt responses and will pay the amount due of $28.
