Re: jeanneau 44 ds air conditioning problem
It sounds like an HPF (high Pressure Failure) failure, not an electrical issue at all. I had the same problem a while back. Easy fix:
There's probably one large water intake leading to a pump and a strainer. This is the pump that feeds water to the AC units. What seems to have happened is that there is air trapped in the line and the pump is shutting down to protect itself. Thats why the fan keeps running but nothing cold is coming out. These pumps are not self priming, so if you open the strainer to clean it, for example, you'll have to reprime the line manually before it will work again.
Doing so is generally easy, All I do is crack the strainer open and let some seawater come out, that usually clears the air out. It's important to just crack the strainer open, don't take it off. With the seackock open you can imagine those results.
I think its this and not an electrical issue, becasue your fans are still running, if it were an overload situation it would trip the breaker and the whole thing would shut down, no fan, no control panel, nothing.
BTW, we sailed a 43DS in NJ for years, we now have a 50DS, where in NJ do you sail out of?
