Cold freezer. Hot fridge

Just got a 2004 Winnie Itasca Sunova 35N.
The freezer gets cold after a while but the fridge stays hot.
That is on home 110 power.
Any suggestions as to where to start or can I expect to just replace it?

I just got it today, and am in the inspection process. I will check those things tomorrow. It was over 100* today and I was too busy to have coffee. I can't recall being this tired for some time.
A good tired though.

Freeze getting cold and food compartment not......

How long has fridge been ON?

Is fridge LEVEL?

*Cooling unit hasn't sprung a leak or fridge would not get cold anywhere

But you could have a blockage between freezer low temp evap coil and the food compartment high temp evap coil

Could also be not enough heat being generated so not enough ammonia being boiled into vapor and condensed back to a liquid to absorb heat from both compartments

Have you run it on Propane?

Disconnect thermistor (temp sensor on Fin in food compartment)
W/O it fridge should run continuously ...that should cause both compartments to get very cold

100*F ambient air temps are not helping!

Brand/Model?

Good news.
I left it overnight, and it is now working well.
It's a norcold.
Funny thing is, I started with the coldest setting.

Waited a couple hours.
Had the problem I described.
Left it overnight on the med setting, and now temps are correct.
I guess it just needed time.
This rig has been sitting for 2 years.
I guess it needed to just wake up.
Quite the relief.


I do have a total noob question:
Since roof a/c etc need shore power to work, is there a reason why I cannot run the generator, and run the shoreline into the coach with a 110 adapter and plug it in.
The seller told me not to do that.
Seems to me, that kind of defeats the purpose of having a generator.
Yes, I have the manual.
I have read it.
There is a lot to learn.

It's kinda confusing to me, on the electrical side.

Seems to me, you CAN do what I explained.
Am I just misunderstanding something?

For better advice post make and model of RV.
Post make and model of the generator.
A picture of what you propose is worth 1000 words.

In general running A/C using a generator is normal. The generator must have high enough capacity. Many 2200 watt generators can do it. Bigger generators will do fine.

How to connect the RV to the Generator depends on the RV and the generator. Most built in generators have a transfer switch. Start the generator, power to the A/C will come on automatically.

Some built in generators have a 30 amp 120 volt socket. The system may require you to plug the RV shore power cord into the socket.

Smaller generators may have a 15 amp 120 volt socket. An adapter may be necessary.

Portable generators require you to plug the shore power cord into the generator.

For better advice post makes and models of appliances.

It's a 2004 Winne Itasca Sunova 35' Class A
Onan 5500 gene.
The roof ac would not come on without shore power.

I put a pic up above of a screenshot of the manual.
I kinda says what you are saying.
Plug the cord in to the receptacle, then run the gene.
I missed that part initially, and was just using home ac into that cord.
So, I guess I answered my own question.
Thanks.
Today will be another important learning day.
I ain't going anywhere until I got all of this down.

Will probably "camp" in my driveway for a night before taking off.
Selling my house and looking for a new one.
Getting stuck somewhere is not an option.
Trying to have all ducks in a row.
Thanks for the help.

On the fridge, sounds like you have a handle on it.

After restoring Porsches and Mercedes Benz for many years, I came to find that low millage was often problems. Do go through the fridge and maintain it to protect it from failure. This includes, but is not limited to:
  • Check the propane system regulator to make sure the system has 11"H2O WC and passes load tests.
  • Clean the Flue Tube and inspect burner assembly.
  • Look up from lower vent, and down from upper vents to check for debris and nests in the cooling unit compartments

Let us know if we can help more, these are suggestions based on extensive fridge experiance.

Good news on the fridge.........

They can take 12 hrs or more to achieve temp.
Absorption process is slow

Generator....
Plug shore power cord into that GEN Receptacle and start your gen
That receptacle s the Gen output...

Driveway camping is great way to use/learn how things work
*LEVEL for several reasons

Your coach was built without an ATS ( Auto Transfer Switch ) that function is taken on by plugging the shore power cord into the gen set outlet .

"The seller told you not to do that. " he should have said you can't do that .

Even if you had an ATS , the ATS would prioritize the gen set power and not allow shore power into the coach while the gen set is running .
