The Cruise Air Salon AC on our Mainship 400 has been acting oddly recently.
About 30% of the time about 10 minutes after I first start up the A/C the unit shuts down and I get a high pressure reading. If I wait a few minutes, then restart it, it runs fine for as long as it is left on. The Fwd unit, which runs off of the same raw water pump doesn't do this.
I figured I had some blockage in the coil, so I flushed the system with barnacle buster but it didn't help. There is very good water flow. I also tried backflushing the system with a hose.
Maybe it's some sort of sensor going bad? If it was a flow problem wouldn't it show up all of the time?
