Hello All

I have a 2000 380 Sundancer that needs a new salon 7k btu ac/heat pump.  Has anyone had success finding the correct replacement model to fit in the tight location of the original.

Welcome to the forum.

Has the issue been properly analyzed to determine that a normal repair cannot restore normal operation?

[wingless]

What diagnostics have already been performed? What faults exist?

[Wailea]

Thanks for responding.
We purchased the boat late in the season 2020. The broker whom I have come to know let me know the previous owners had the system repaired but not sure of exactly what took place only that it stopped working again shortly after.

The system is very straightforward to analyze.

Each system on my 2000 380DA has been repaired by me and both are going strong.

There are many steps that should happen prior to swapping the system based on reported third hand diagnostics.

[Wailea]

Understood thank you. Is the first step to fly you to Wisconsin : )

[Wailea]

Where would I start. Is there some information available to guide the diagnostic process.

[wingless]

I don't know the diagnostic process for having me return to the "Eat Cheese or Die State".

For the A/C, what are the symptoms?

[Wailea]

You will be happy to know we altered the Moto a bit. To we are all going to die at some point let’s eat cheese.

The only thing I know about it is it does not generate cool/cold air. Not much of a starting point I know

[wingless]

Boat will probably be splashed in a month.

Do an analysis at that time to get past the "understand it's broken" point.

[Wailea]

Understood and I don’t want to bore everyone with my ignorance but aside from turning it on lowering the temp and having no cold air come out I honestly am not sure what the step to analyze is

[wingless]

The Cruiseair SMXII heat pump systems installed on this boat include integrated diagnostics that utilize the two-digit seven segment control pad display to assist in the problem diagnosis. A problematic unit will display a two character fault code like LO or HI that help to understand the issue.

Additionally, the act of turning on one heat pump, then additionally turning on the second system, while monitoring the raw water pump will aid in diagnosing the trigger modules. Both of mine have failed during my long term ownership.

The keypad modules fail, requiring replacement. Both of mine have been swapped during my long term ownership.

Your being boring is a problem that I am unable to provide assistance in correcting.

[Wailea]

Actually on a flight to FL as I type this figured I would bring the problem to you….
So when the boat is launched perhaps I can have you walk me through those steps?
