Don't know, but I suppose that is because they've promised you
sub-zero and it's not a question of letting you decide how hard the
ice cream should be. (Although in my fridge the freezer temp control
is in the fridge part.)

Is this a normal de-frosting cycle?

Yes, it's the normal ice-water-ice-water cycle. Called IWIW in the
trade. It is designed to make the ice cream icy.

Is it making any noises at all?

Is it still plugged in? Maybe the cat unplugged it?

Can you see the coils? Is there any ice on them?

Fridges can sometimes be DIY. When mine wasn't cooling well, it was
just because there was a mouse stuck in the little fan. I took that
out and two weeks later, another problem. I guess I or the mouse had
nudged the insulation because this time it was insulation in the
little fan. I don't think that's your problem, but check it out again
and get back to us.

recently my friges defrost timer broke and stuck in the defrost mode,
you could have other issues, get a repairman out, it could be many
other things
