    I have an 04 320 with twin Mag Horizon w/ V-Drive. I left my boat with a/c on. Came back 2 days later. It was off. Reset the breaker on the main panel and nothing. Outlets work, TV works and shore power is at correct voltage and on a 30 amp plug. Everything is off including a/c thermostat. Working just fine prior to this issue.

    Was the breaker tripped when you arrived? Start simple check the strainer.

    So I am not trying to Hijack this thread but I have the same issue. I did check my panel and the error code says low on Freon. So 03/04 used R-12. Does anyone have any recommendations because R-12 is stupid expensive....

    I have used Enviro-Safe in the past. Its an R-12 alternative that does not require seals to be replaced like R-134A retrofitting does.

    Thanks for coming on. Everything just like I left it. Only a couple of days went by. Everything else working but the a/c. The thermostat is not on either. Totally dead. I was going to check if power is getting to the unit but I don't even see where the power goes into this thing. Rookie

    Have you considered the possibility either the aircon breaker or the Thermostat/control is dead? If everything else on 110 functions but the aircon, good possibility it’s one or the other.

    If you have the SMX control, a company in PA, (Flight Systems) remans them.

    Its not clear yet to me, are you saying that everything 110 V works on the boat, just not the A/C?
    I believe if you gain access to the AC unit and follow the power cord from its control box you will find that it plugs into an outlet. You can check for 110V there.

    Thank you. I had no idea i thought it was direct wired so didn't bother chasing it down. You are correct everything 110 works except the air conditioning.

    Sounds like the power box of your unit is shot but that is not a common problem with most brands. Use a multimeter and 1) confirm that the outlet has 110 going into it and 2) you also have 110 going into the board. Follow the power wires into the power box (unscrew the cover) and check where the black and red/white wires connect in. Also check that the control pad is properly plugged into the power box. If you have power into the power board, then you either have a bad board component, or the control module is bad. Taks some pics and let us know the manufacturer and model number.
