Cockpit freezer performance

[atruckenbrodt]

I have the Novakool WF1900 cockpit freezer on my C30S. I'm not happy with the performance: Best case, the temperature gets down to -8C, often only -3. It takes a long time to freeze items which I put in (like prawns). Nothing seems wrong but that just not a good freezer performance. Anyone has seen similar issues?

I have an old Novakool R4500 in my C26 - fridge mfg date reads 2007. Very reliably cycles -10C/-15C even under extreme summer-oven cabin conditions. Amazing.
