Why is the ice cream soft when the rest is frozen?
The short answer
Because ice cream is the most sensitive thing in the drawer. It softens over a small rise that leaves everything else rock hard, so it is an early warning rather than a fault of its own. Sub-Zero Appliance Repair Denver — (303) 729-0972.

Before you call
- Check the freezer setting on the panel. Sub-Zero publishes zero degrees Fahrenheit for the freezer on an electronic control.
- Stand a thermometer in a glass of vegetable oil in the middle of the freezer, halfway in every direction.
- Read it after twelve hours, not after twenty minutes. That wait is what the manufacturer's own instructions ask for.
- Move the tub away from the door and out of the top basket, then try the same test again next week.
Stop here and call Sub-Zero Appliance Repair Denver on (303) 729-0972 if the oil reading sits above the figure Sub-Zero publishes after a full twelve hours.
What it usually turns out to be
-
The tub is in the wrong place
It rides in the door or the top basket, where the air is least settled, while the packs at the bottom of the drawer are fine.

-
A setting that has crept up
The panel is above the freezer figure Sub-Zero publishes, often after somebody adjusted the refrigerator side and caught the other control on the way.
Quoted after the diagnosis
-
Real drift in the compartment
The oil glass reads warm after twelve hours, the grille is furred with dust, and the tub is only the first thing to have said so.

When it is worth a visit
Once the tub has been moved, the panel checked and the oil glass read, you either have a reading that matches the published figure or one that does not. A reading that does not is the point at which the cabinet, rather than the ice cream, is the subject.
The tub as a thermometer
There is a useful accident in a freezer full of shopping: one item in it responds to a change of a couple of degrees while everything around it carries on looking the same. That item is the ice cream, and it is telling you something the frozen peas cannot.
What it is not telling you is how much. Soft is not a number, and the difference between a tub that has been in the door for two weeks and a compartment that has genuinely drifted is a reading, not a texture. Sub-Zero’s own advice on checking a freezer is a thermometer with its bulb under vegetable oil, standing in the middle of the compartment, left for half a day. Half a day, because anything shorter measures the door rather than the freezer.
Take that reading before you touch a control. If it comes back where Sub-Zero says a freezer should be, the tub has a position problem. If it comes back warm, you have a specific thing to say on the phone, and specific is what gets the right parts onto the van.
Follow-up questions
Why does ice cream go soft before anything else?
Because it is not simply frozen water. The sugar in it keeps part of the mixture liquid even when it looks solid, and that part grows as the compartment warms. A bag of peas is water and cell wall, so it stays hard through a rise the tub has already noticed.
What should the freezer be set to?
Sub-Zero publishes zero degrees Fahrenheit for the freezer, and describes anything from minus five to plus five as the normal band a freezer section works in. Ring Sub-Zero Appliance Repair Denver on (303) 729-0972 if yours will not hold inside that.
Should I just turn the freezer down a notch?
Not before you measure. Turning a control down masks a cabinet that is drifting and costs you the one clear symptom you had. Take the oil reading first, give it the full twelve hours, and then change a setting knowing what it was actually doing.
