Cruise Air cooling pump won’t shut off

[northshoreone]

My salon AC unit, when power is on to it runs the cooling pump contiually even if the unit is shut off.The only way to shut down the cooling pump is to kill the breaker to that unit. The pump then cycles properly for the othe units on board. The AC guy has replaced the trigger...worked properly for a few days then right back to the same old thing. He returned when I wasn’t aboard and rep,aced the board on the condenser and said that took care of it. I returned to the boat three days later to find that it’s doing the same thing as before, pump runs non stop unless the breaker is off. Loosing faith in the AC guy so looking for suggestions from you guys on where to look next for the solution!

It’s a Cruise Air 24k unit by the way

I had a a/c tech tell me pump shutoff is controlled by a relay.

That was my problem before the condensor went. See my post
