I have a 7000 BTU Cruisair in my 260DA. It has the SMX ir controller. My heat works just fine. The seawater pump functions as it should when I put the heat on and the results are fairly good.
However, if I try to switch to AC, just the fan runs, no seawater pump, and I am not sure if the compressor is kicking on or not. Is there any quick and easy diagnosis I can do before calling out a marine HVAC guy? Keep in mind I do not need the air conditioning right now, I just wanted to test it as a matter of routine.
Also, could this be anything to do with the weather? The seawater is probably 42-45 degrees at my harbor and the outside temperature has been in the 50s. My HVAC guy for my rental properties has said that AC shouldn't be run unless it's above 65-66 degrees. Does that apply here with a water-cooled unit?
I have reset the unit twice on the controller, cleaned the seawater strainer, and also both filters in the rear berth. The controller does not show any faults/error messages and the system has not powered down. My air conditioning worked just fine last year by the way. Hoping I don't have a real problem, but...
