Cruisair SXUF18 Troubleshooting

[Atalla]

Hey folks. After a excellent weekend cruising the Puget Sound, it is clear that my AC/Reverse Cycle Heat is not in tip top shape. Fan is fine. Even kicks on and starts blowing heat relatively quickly. After some amount of time it just stops sending heat and starts blowing outside air. It is well below the target temp when this happens. I haven't dug into this problem at all but plan on pulling the mattress and getting into it in the next week. Figured I'd ask if anybody has any tips on what I should look for. Fuse somewhere? Dirty filter? Some thermostat control board that gets flakey? Any suggestions welcome. After my generator repair work, it is clear I should ask for suggestions first so I have a list of things to look into before going to the boat.

Thanks.

Check sea-strainer. Make sure you're getting good water flow.

Seriously, after hours invested in revitalizing my Kohler genset after salt was slowly killing it, you'd think I'd have already done that. I do see pretty solid water flow out while it's running. Thanks.

Realize I never posted my resolution.

Yuck is that the air filter?

That would be the air filter.

I had to hose it down in my driveway to get it clean.
