you said marineair (dometic?) is this new to you, has it ever worked since you had the boat?
does your thermostat look like this?

if so have you looked at the programming set ups to verify how your thermostat is programmed. there are several paramters that can be set including it being set to either only heat or cool. only or auto changeover. this can prevent this compressor from coming on and also compressor time delay. if you dont have the small card with the instructions and settings check your manual or google the passport manual if not i can email you this. it might be worth a shot. i set mine to heat or cool only and change it for summer or winter . easy to check and program.
i just googled it for you
here you go

also if you look at p12 you can set the pump to cycle on to verify the pump i would leave it in auto to cycle with compressor but you could change it to temporary verify pump output. again if there is more than 1 ac unit and only 1 pump there will be a pump control/relay box somewhere.
