Air Conditioning Problem

[Still LauCo]

Hello Again-

I've got an AC issue. I have a Marine Air system with the digital readout.

The heat works, but I can't get the AC to kick on. For instance, my cabin is at 70 degrees right now, if i move it to 75, the heat kicks on, I can hear the compressor, etc.

If I turn it to 60 degrees, the fan goes on, but the compressor doesn't kick in, and I get nothing. Any ideas?
Thanks!

Do you see water from the water pump coming out when either the A/C or heat is turned on? When my boat was delivered a month ago, the water pump had to be primed.

Water pumped for the heat.

That would be water coming out of the side discharge on your hull. :thumbsup:

Low ambient water temperature, i.e. the cooling water passed thru the compressor's cooling coils, will prevent the system from cooling. I doubt you have a problem, other than living where the temperatures are only suitable for a penguin!
