[C320-list] Refrigeration Diagnostics Assistance

[KEN GEIGER]

Hi Ken.  Your 320 as a 2003 I newer than our 2000 #765 and the other responders so there may be differences.
Our fridge is 12volt and controlled by a panel switch assuming the batteries switch is turned on to one or both batteries.  If you are going to leave the fridge on you need to keep the batteries charged some how.  Battery charger needs shore power.  Lose the shore power with fridge on will deplete the batteries.
So you need to id the fridge and it's power source. Do you have a wiring diagram for the boat.  Then find out if you have power to compressor.  The thermostat may have an off position and then clicks to coolness levels. 
Fridge drain on our 2000 is fed to a 3 way valve under the head sink, as is the shower drain.  We select the correct position of the valve, turn on the shower drain switch on panel and then turn on the switch on the vanity wall by toilet.

10 days ago, I left KIA ORA (2003 Catalina 320) plugged into shore power with the fridge running. with a couple of beers and some water.
I came back this weekend and the fridge was not running.  The switch was still on and the shore power plugged in.  I know that the yard would have unplugged to boat to do some other work during the week.
Normally, I can hear the compressor running but nothing.  I checked the thermostat, I reset the switch on the electrical panel, nothing seemed to make a difference.
I tried to find the compressor.  I thought it might be in the port locker but what i thought might be the compressor was actually the battery charger.  I did not look in the port stern locker.  Did not think about that until now.
I put a block of ice in the fridge for the weekend, which created another problem, lots of water in the bottom of the fridge.


  1.  Is there a fuse or circuit breaker that i should be checking?
  2.  Anybody know where else to look for the compressor?
  3.  I thought there was a drain for the fridge (based on some other reading on the C320 Association site) but I could not find it.  I tried to get the water out manually (jcloths, tea towels, etc)  I either need a manual pump or really big sponge.  Is there a drain in the cold box and if so, is there something i need to do to open it.  Assume it drains into the bilge.

I tried getting into the 320 site to do more research but i am having password issues today

Thanks
