Does anyone know if there is a fuse or breaker of some kind for the AC system in the bilge or elsewhere on the 330DA (98). Mine was working and then shut of. WHen i put a multimeter on the power leads on the CrusAir box there is no reading so somehow the power is not getting to the box. Help?
 
The breaker is in the electric panel next to the microwave labeled A/C. Is the display lit at all??
 
yeah the one on the panel is on no problem there. I was just wondering if there was a fuse or something in the bilge or somewhere else. The panel doesnt light either. Like i was saying, when i turn the breaker switch on and put a multimeter on the leads that feed into the crusair box, there is no power getting there from the wiring. I cant figure out why. THe shore power is fine and everything else on the b side shore power works.

Cycle the shore power off, pause, then back on. Make sure to switch the A/C switch on the interior panel off and then back on after you have cycled the power as well.
 
If the meter on the side that has the A/C (microwave too) is reading 110 volts then you have to open the panel and check the breaker...
 
That's really odd. There wouldn't be anything between the panel breaker and the unit. Perhaps a bad breaker? Did you check both the in and out terminals of the breaker with the multimeter for power?
Also double check the neutral connection at the bus.
Let us know what you find out. That's a strange one...
 
I think the ac on a 330 is on its own circuit like on my 340DA. So if the main breaker at the shore power plug tripped, you won't have any power from there forward. Check that one first.
 
ok so duh. i guess i was just really hot yesterdfay when i was checking the current (it is TX after all). I must not have fully touched the multimeter to the terminals on the cruisair box. i am getting full voltage to the box, so i guess its the box itself. Does anyone know if these things are serviceable? I see a fuse on the board, but it looks ok. I am just wondering if i should waste time trying to find someone to repair or just get another?
