AC Line 2 Port Systems Switch, AC Refrigerator Issue

[Chance]

Hello all, new to a 360 Sundancer, can someone please tell us what the purpose of the "Port Systems" and "Starboard Systems" switches are under Line 2 on the panel?

Also, the refrigerator and freezer won't run when the AC switch "Refrigerator/Freezer" is on and plugged into shore power, but both refigerators and the freezer will run under the DC side when the soloniods are on and "Refrigerator" is turned on. All other systems on AC, incuding the microwave, etc. run fine when plugged in and the AC Converter is on, but the refrigerators won't work.

Any help is appreciated, we're learning quickly but a few things have thrown us for a loop. Thanks.

The port systems and starboard systems breakers are for the electrical outlets and possibly the TV(s) as well. Also, on my boat the cockpit fridge is tied into the port switch but the cabin fridge and freezer have a dedicated breaker like yours.

As to why the fridge doesn't work, make sure none of the GFCI outlets are tripped. If that doesn't help, I'd suggest pulling it out and plugging in a lamp or something to it's outlet to verify that its actually getting AC power and go from there.

Thanks, I'll check those things this weekend, I guess at worst we can use off DC side and turn off when away from the boat until we can figure this out.

I would check the power supplies behind the fridge and freezer there is A relay that flips one way or the other 120 or 12 volts I had to replace them both power supplies last year same kind of problems you can find them on line for about 120 bucks when I installed my new power supplies I installed A surge suppessor good luck
