I have a never ending problem with my freezer
My 6 years old Waeco CF-25 CoolFreeze is having troubles since few months and no technician seems to solve them. I really believe that the experienced sailors here might come with a solution.
As I have a built-in fridge in imy boat, I use my portable Waeco unit as a freezer
(about -12'C). Since 6 years, it has been working non stop as I'm a liveaboard
in my 34ft sailing boat, in Western coast of Turkey
Last month, I have noticed that the unit is working for very very long periods of time (like 6 hours for example) to reach the desired temperature, in my case from -10'C to -12'C. Then it stops and rests for about 45 minutes then the temperature drops back to -10'C and starts again for at least 6 hours.
First thing I did, I replaced the cooling
fan. Nothing changed.
Secondly, I took it to technical service
and they replaced the refrigerant. After that, I came back and left the unit to work empty to test it (put the frozen food
in a neigbour's freezer) and it reached -12'C from +3'C within an hour.
I thought it was okay, problem solved
and put the things back in.
However, same thing happened again and it started to work continuously for very long periods of time. Obviously draining the batteries.
No red error light is shown on the unit.
I cleaned the compressor
, condenser coils, etc.
Moreover, there's very fast ice building on the inner walls of the unit (near the top).
And interestingly, there's excessive condensation
on the outer walls of the unit where the dark grey part meets the pale grey part. The amount of water
is so much that under the unit is always wet. I had to put layers of newspapers underneath; and I replace them frequently. Also, those water
drops on the sides of the unit are cold although the ambient temperature in the boat these days is about 32'C. I try to wipe the water but it's back again very quickly in few minutes as if I haven't wipe it.
As you see, I am really helpless. I'm out of solutions and I don't know where to look, what to check, what to replace next...
I don't if anyone here has faced a similar problem.
- Anything you could say or suggest will be deeply appreciated.
- Thank you very very much.
