last weekend we were on a mooring ball. Took the dinghy for a few hours so I shut EVERYTHING off. Maybe I should not have shut off the 12v breaker because since then, my main refrigerator won't get cold.
The freezer section does have some ice in it, telling me the unit is at least running. But the main compartment is in the mid 50's f. (I got a fridge thermometer) in the manual it says a red light will flash a certain number of times to denote a particular issue.
The red light is not blinking at all though. Green light is on solid.
The other two refrigerators are running superbly..
This is a WAECO CR series
Any ideas are more than welcome.
 
My answer has nothing to do with a marine fridge, but I just "fixed" a similar issue at home. Turned it off. Let it defrost. And cleaned the coils. Now very cold. Good luck.

Coils on the back of the fridge?
 
Coils on the back of the fridge?
At home they where on the bottom. But yes the coils that control the cooling/heat exchange. May be on the back of the smaller marine fridges. Get an appliance brush -- long and narrow to get between everything and to knock anything off.
 
I hope you're able to resolve. Mine did the same thing and it turned out to be a non-repairable coolant issue (on an 8-year old Isotherm fridge!). We had to replace it before our long trip this summer.
 
They also sell “no rinse” coil cleaner in an aerosol can if you want to go even further than just the coil brush while you have it pulled out.
 
I pulled it out. Unplugged 12v and 110v. The whole unit was actually pretty clean but I dusted it all off. Complete de frost.
Powered it up last night. This morning, Steady green light (normal operation) on 110v. Switch to 12v and I get a single flash red light (low power supply).
The plus side is it got down to 30f. I'm going to try the 12v again soon.
See what happens.
 
If the power supply is faulty there are a few places that can fix them.

There's one place in Chattanooga TN where a local boater took his and they fixed it up.
 
If the problem is only on the 12 volt side: Check to make sure your batteries are healthy before going to the power supply.
 
OMG Over $400 for that little power supply? All it is, is a 25v2a power supply with a transfer relay. I replaced mine with a 12v12.5a power supply and a 20 amp DPDT relay. I think I'm in for less than $50.

Make sure the fan is running and blowing good.
