I'm looking for some help with a Mermaid Marine
AC system. When I turn on the breaker to the system and put it in "cool" mode I immediately get a high pressure fault.
The troubleshooting guide says the high pressure switch needs to be reset. I think I found the switch but it is either not tripped or I don't know how to reset it. I believe it is the device with the giant reset arrow pointing to it:
I pushed down firmly on the red rubber boot cover, and it seemed like it was in the normal position. Any advice on what do to? Does anyone know if this switch is normally open or closed?
