Ice cream?

Frig setting on high freezes the food in the frig section but ice cream will never freeze no matter the location in the freezer. I will be buying a little 3.5 or 5 cu. ft. freezer for next summer.

Hi,

If I understand you correctly, you added a fan in the food part of fridge and not the freezer

YMMV... but the fan in the fridge makes the freezer colder. If you think about it, the freezer temperature is heat transfer conduction from the freezer. Pushing the air across the fins not only helps convection, but also conduction... or I'm full of brown stuff and just have a good fridge :)

Freezer and food compartment are completely separate...no connection between the two compartments

Freezer Low Temp Evap Coil gets the coldest ammonia to absorb the heat from freezer THEN that ammonia tries to absorb heat from food compartment.
The colder the freezer gets the more capacity the ammonia will have to absorb heat from food compartment

Freezer temp will affect food compartment temp.....food compartment temp does not affect freezer temp
Warm food compartment temp will cause thermostat to turn heat source on more frequently which in affect will cause freezer to get colder EVEN if food compartment does not get colder...

Fan circulating the cool air inside the food compartment helps to even out the overall temp in food compartment regardless of freezer temp

The coldest spot in most RV fridge is the back lower left hand corner. Keep the carton shoved back in that corner.

I almost forgot that not all ice cream is created equal. I only buy Blue Bell at home, because it’s still sold in full half-gallon tubs, and they don’t whip a bunch of air into it before filling them. It freezes hard as a rock if your freezer goes low enough. I don’t even look at all that other phony stuff next to it in the grocery store.

If your favorite brand is sold in three pint containers, it’s not REAL ice cream, and it will always be soft. Every ice cream connie-sewer knows this.

:):)

Guess Im in the minority. My freezer won't freeze 'scream' either.

Freezes everything else quite nicely.

The working medium passes through the freezer first, so adding a fan seems to me to do nada for the freezer. I know it makes no difference in my freezer whether the fan is "on" or "off".

Adding a fan to the "back" (chimney) of the fridge does improve cooling time and freezer operation.

I added a computer fan inside the fridge. Freezer easily keeps ice cream frozen.

That's the carrageenan, and guar gum they put in there to add "body". Good ice cream has neither, but getting harder to find.

That's why the cheap stuff never melts completely, and there's a lump of "stuff" that's left.

Our Dometic Refrigerator freezer compartment has three zones- the top will freeze anything hard as a rock, the next two shelves will keep frozen food solid but takes a day or so to freeze items not already frozen. The bottom shelf keeps items colder than the refrigerator but rarely will freeze anything.

So we keep ice cream at the top and it stays hard.

It does seem though that some ice cream now days doesn't seem to freeze hard even at home in a residential fridge. We currently have a 3 gallon bucket of ice cream from Kroger that has stayed soft for about two weeks so far. I experienced this with other ice creams as well (usually the cheap stuff).
