My guess would be 32 F or 0 c. I base this on the fact that to set a thermometer you insert it in a glass of ice and cold water. The set point should go to 32 F. If it were vastly colder than that it would skew the reading of the thermometer and you would not be able to accurately adjust it.


This is my guess as well. I set my thermometer to 32 F using the ice water trick shown to me by several HVAC repairmen. But I've been wrong twice in the last decade so this may be number 3.

My guess is about 20 F

32F is a bad idea. Many foods freeze at temperature below 32. Anything containing sugar or salt will not freeze at 32 as they are freeze point depressants. When sugarless diet sodas first came ou,t there was a freezing problem while in transit that they did not have with original sugared drinks At least as low as 20F, for a refrigerator.

At 0ºF, "ice cream" is almost rock hard. I microwave a full half gallon for 25 seconds to facilitate eating. As the volume decreases, I reduce that time accordingly. Yes, home freezers are set to 0º F.

My LG freezer is set to -1F. Diet type ice cream (low fat) are rock hard and I put them in Mic. Higher fat, "real" ice cream is scoopable at those temps and doesn't need microwaved. I say "real" because the Stone Ridge ice cream says right on the carton "real" ice cream. It's my favorite as well.

0° F
Keep your appliances at the proper temperatures.
Keep the refrigerator temperature at or below 40° F (4° C). The freezer temperature should be 0° F (-18° C). Check temperatures periodically. Appliance thermometers are the best way of knowing these temperatures and are generally inexpensive.Feb 9, 2021

First, and most importantly, there is no such thing as "cold". There is only an absence of heat. We often say that something is colder than it was before, however, what we really mean is that it has less heat content than before.

Also, there is a difference between temperature and heat where the temperature is the intensity and heat is the content measured in Btu. An example would be comparing a match to a bonfire.

Water has a specific heat of "One" which means that it takes one Btu to raise (or lower) the temperature of one pound of water one degree F.

It takes the removal of 144 Btu of latent heat to change the state of water at 32-deg. F to form ice at 32-deg. F. The ice can't drop in temperature further until it has reached equilibrium with the other items in the freezer.

If you keep your freezer at 2-deg. F and the mass of all of the items in the freezer have reached 2-deg. F, then the ice will eventually reach that temperature as well.


When the water changes state to ice, the specific heat changes from one to 0.5. Thus the ice can reduce in temperature when 0.5 Btuh is removed.

A while back at a friend's house he offered me some ice which I was happy to get. Until, I TASTED it, it was warm ice. It was not near as cold as the ice I was getting at home, so a search ensued. The results were clear ice which had to make myself but it is colder and better, harder for chewers like myself. Watch your teeth. I now like pellet ice but the machines to make it are expensive and some are not all that good. But $3000 is a bit much for ice. Do I LOVE ICE, yes!!!!!!!!!!!!

Hate to differ but that absence of heat is defined as cold. There is opposition in all thing, hot and cold, up and down, right and left, in and out. It even gets microscopic and atomic.

Seeing all the crazy answers to this question makes me wonder how the US ever became the economic and science superpower that it is.
