Lunaire Salon AC and blower issues

Post by joshhunsberger »

Hello!
I own a 40' 12 meter Aft cabin boat and we are having issues with our Air Conditioning in our Salon, our current setup is I have a Condensing Unit behind the Shower wall in the Aft Cabin Head and an Air Handler/Blower under the Helm on the Bridge. I went to power on the unit in the spring to test everything and the other 2 units in the Forward and Aft cabin worked fine! But when I powered on the Salon AC I got a CLF error on the Display, which I find out is a Compressor Load Fault error! Then after that the unit would cycle on and off every 2 minutes or so, even if it was off. So I had to turn it off at the Breaker. So I tried replacing the the Control Panel(FX-1) with one from Coastal Climate Control and I verified with those guys that I wired everything correctly and now we are not getting anything. The panel turns on but the AC Unit does not! So my question to the forum is can I just replace the Condensing unit by itself, or do i need to buy a whole new Closed system with condensing unit and air handler/blower? If I need a whole unit what would be considerable replacement for that size of a space? Thx!!

I was talking to Bob on this , and we both feel there a added issue with the new control as it is doing nothing . You may want to hook up the old one and recheck the system . Did it have water flow on that unit ?

Hello... I had tried hooking up the old one and that did nothing as well, it would just cycle on and off every couple minutes even when there wasn’t power, which is why I would have to turn it off at the breaker. I also talk to the guys at coastal climate control and they said that the new panel was fine. If the condensing unit or the air handler is bad what kind of behavior would I experience? I replaced the control panel on the forward cabin air conditioning unit last year and didn’t have any problems with wiring that one. Thx!

Sorry for the late response... But unfortunately they are dead and have to purchase a new AC and to make matters worse we lost the unit in the Aft cabin as well. So we bought 2 new Marinaire units! But now i have to find some way of selling 3 pretty much brand new Coastal Climate Control FX-1 modules? Any thoughts on that would be great...

I too am having issues with the saloon air in my 12 meter aft cabin. Similar symptoms, it tries to run for 1-2 min and then the breaker kicks off. I had an A/C guy check it out and he put a booster condenser to try and get the compressor to kick, but no good. He said the compressor is shot. Problem is given the age of the unit (1989) and being split system, no one wants to work on it. Trying to figure an alternative. thinking of getting a single contained unit and replacing old unit and running duck work. I'd hate to forego the ceiling handler, but i'm running into a brick wall.

Surprised no one will work on it . No issues around here see the a/c guys on older boats all the time . Maybe a good used compressor/condenser unit ? Or new that is r22 combatable , maybe a different brand . And your using a Marine AC guy/gal ? Right ?

Yes, marine A/C guy. I think it's the age and the fact that they seem to be very busy. Just to get them to come look at it was a struggle. Not many guys around here (Buffalo NY) work on marine A/C.
