Freezer doesn't keep ice cream hard

[Doc Mark]

I guess I have the opposite problem from the other refridgerator threads. When we set the temp on the door to maintain the 38-40 degrees in the fridge, the freezer doesn't keep ice cream frozen hard. Since it is a "one setting fits all" I am at a loss as to what to do. Any suggestions folks? PLEASE ! I HATE mushy ice cream

Assuming the freezer's door seal integrity is intact and performing as intended and there is no unusual frost build up inside, you might try a temperature adjustment by sliding the thermistor up or down the fin. Higher up the fin would give you a slightly warmer box, and down would be cooler. It would be a very subtle change.

Hey cuz...is it safe to assume that your are starting out with hard ice cream?

[Doc Mark]

Indeed it would.

My personal opinion is that 38-40 is a little high. I like my frig to stay around 34 or so and my ice cream is usually pretty hard. However, I do like my milk cold too.

You didn't mention the make or model of your fridge. If you know that information you can go to Bryant RV web site. Go to the service document section and check the model numbers, it is likely that you can download the service manual for your fridge. Hope that will help.

38dF is marginal for the safe storage of milk.
uch better off to be at 36dF in the frig.

Doc Marc, is the freezer frost free? If so, the heater element may be the problem. This heat element cycles about 21 min. each 24hr period, melting any ice build up around the cooling pipes.If a build up of ice is present on and around these cooling pipes...air is not being allowed to circulate, thus preventing the air from cooling. A build up of <span class="ev_code_BLUE">ICE</span>will actually prevent the refriderant from cooling. Also check the heat element timer.

Since warm air rises, it appears to me that the thermistor mounted higher would result in a colder box.

The therrmistor is not sensing (or shouldn't be) measuring the temperature of the air, but the temperature of the fin atttached to the cooling unit evaporator tube. Usually the fresh food section has an evap tube shaped like a rounded bottom V laying on its side with the opening to the left. The fins that you see on the inside of the refrigerator are secured to this tube. This tube absorbs the heat inside the fresh food compartment through the fins. The closer you get to the actually tube the colder it will feel. Depending on the make & model of the refirgerator the manufacturer positions the thermistor in a position that is critical to proper operation. THere are some models that do not have an electronic adjustment and moving the thermistor will change the operating temperature. I would recommend that the thermistor in this case be place where the manufacturer dictates and then diagnosing the operation from there.

Once again you have said the magic word. I.E., fin temperature versus air temperaturre.

Thanks to you all for the information. I haven't had a chance to act on any of it as we were out of town (sans MH) for our 39th wedding anniversary. Will get working on it this week.
