Refrigerator Not Cooling Good
Freezer holds at about 20 degrees. This is not cold enough to keep ice-cream frozen.
Fridge holds at about 35 degrees on the top shelf right next to the cooling plate.
Lower shelf is at 40 degrees or more.
These temps are after overnight of not opening the unit.
During the day while using the fridge will get up to 40-45 degrees on the top shelf.
Ice takes a good 12 hours to freeze if not longer.
Cabin temps are below 70 when running the A/C and about 80 to 85 max before we start cooling it back off.
Good ventilation around the unit.
I have checked the coils and they are good and clean.
Does not seem to matter if on AC or DC power.
Thermostat set to max. Has new thermostat as I thought maybe that was the problem.
I am wanting to replace with a new unit that will work more like a home fridge (close to 0 in freezer and hold 35 everywhere in the fridge). Thinking about the Vitrifrigo as they seem to have the best reviews.
Thoughts?

Re: Refrigerator Not Cooling Good
And definitely check those door seals as RobGunn says. Just a TINY leak in the freezer section can make a HUGE difference!

Re: Refrigerator Not Cooling Good
Frost - not to the point that it needs defrosting yet.
G36 - does your virtifrigo seem to be consist temps throughout or is it warmer at the bottom of the fridge?
Do they have a cirulation fan inside the fridge to maintain constant temps?
The NovaKool does not and I think that is one of the problems. When it gets cold enough up top - the bottom is still warm for a fridge.

Re: Refrigerator Not Cooling Good
I tried putting a battery fan in the fridge for a while but it really did not help much.
Midnightsun - I will try giving Novakool a call.

+1 on this. My almost-vintage motorhome has its original Norcold unit and a while ago developed issues which were solved by changing the door seals. Also, I noticed that a good "reboot" (turning the unit off and waiting about 24h before turning it on again) worked to get it fully functional again.

Re: Refrigerator Not Cooling Good
I went ahead and defrosted (even thought it did not need it).
Temp at the very back top shelf is holding at 35 degrees. 2nd shelf is at 40 and 3rd shelf is at 45.
And that was with not a lot of stuff in there (some drinks and a 1/2 gallon of milk laid on its side at the back).
Freezer is holding at about 10 degrees and takes ice about 12 hours to freeze.
Thermostat is on 7 (max).
No air flow or any moisture around seals so no leak there.
I am thinking the compressor is starting to go out and it is just not cooling good enough. Even though compressor sounds fine it is running 100% of the time.
