It works better in a hot room. I am remodeling and the fridge down stairs is not in a heated room and it is winter now so it is kept at about 30 to 40 degrees Fahrenheit ambient temperature. It does not freeze the products in the freezer. When I leave the upstairs fridge room unheated it does the same. The only thing I could think of is that the coolant has to be in a warmer ambient temperature for the coolant liquid to boil and vaporize giving you the -27 degrees in your freezer.

How does a refrigerator of freezer work to keep things cold?
This gas in your refrigerator draws heat away and makes the objects cold
Does refrigerator affect temperature of room?
A refrigerator is a "heat pump." That is, it pumps heat out of a cold area (inside) to a warm area (the room). Thus, when working at its best, a refrigerator is a heater. However, the laws of thermodynamics assures us that it will always use more energy than it puts to work, so that extra energy will also heat the room. That is why your air conditioner (another kind of heat pump) is outdoors: if it were indoors, it would heat the room it was trying to cool!
How is a refrigerator an example of a heat mover?
Normally, heat moves from a higher temperature to a lower temperature. Devices that use work to move heat are called heat movers. A refrigerator is an example of a heat mover because it takes the heat from inside of the refrigerator and moves it to the outside. The 2nd law of thermodynamics allows this to occur if work is done in the process. A refrigerator does work as it moves the heat from inside the refrigerator to the warmer room.
Is it possible to transfer heat from a cold reservoir to a hot reservoir?
yes, but work will have to be done. a refrigerator is an example.
The extent of cold work that a metal can withstand depends on?
The extent of cold work that a metal can withstand depends on the recrystallization point which is usually carried out at room temperature. The cold rolling and cold drawing of metal significantly improves surface finish.
Do batteries work better cold than room temperature and hot?
Yes, cold weather does make phone die faster.
How does a refrigerator or freezer work to keep things cold?
Both the refrigerator and the freezer have fans to keep it at cold temperatures. PV=RT; A compressor raises the pressure of the gas volume V and temperature rises. A fan blows away the heat into the room. Then the gas pressure is dropped in the refrig cold room and the temperature drops in the cold room, PV=RT. The heat in the cold room heats up the gas and the volume goes to the compressorr again, ec,etc,etc.

Why is it unwise to try to cool a room by opening the door of the refrigerator?
To operate the refrigerator, requires a lot of energy. When the refrigerator is running, some of that energy is used to cool the interior (about 80% of said energy.) But this is not "making cold." A refrigerator cools by moving heat from inside it, to the outside. This heat is dissipated into the room by the cooling fins on the rear. The whole process happens silently and slowly, and we never notice it. So even though the inside of the refrigerator may be cold, the process of making it cold warmed up the entire room, plus 20% (the energy wasted in the conversion process.) Thus, opening the door to cool the room will never work, because the refrigerator cannot make cold, it can only move heat around. And in doing so, it itself always dissipates 20% more than the energy moved, which ultimately ends up as heat, further heating up the room. Ironically, the room would be cooler without the refrigerator in it.

Can gnats live in the refrigerator?
Gnats can live in refrigerators that do not work. However, they can't live inside a cold working refrigerator.
Do bananas turn brown in the refrigerator?
A banana will eventually turn brown on a coutertop at room temperature and inside a refrigerator. The difference is it will turn brown faster in a cold space, such as a refrigerator.The skin turns brown or black faster in a refrigerator, but the banana meat itself does not ripen that much more. In fact, it is recommended that ripened bananas be frozen to preserve them even longer. The cold temperature of a refrigerator encourages an enzyme (polyphenyl oxidase), which is naturally found in the banana, to polymerise phenols in the banana skin into polyphenols. Polyphenols are similar to melanin, the pigment responsible for the color in our skin. This is what blackens the skin of the bananas. Despite the color, the cold temperature will keep bananas firmer than a banana that has been left at room temperature for the same amount of time. The enzymes that break the starch into sugar, which makes the banana soft and ripe, work better at room temperature.
Why is your refrigerator not running cold nor is the freezer?
because it doesnt work anymore. you need to get it fixed

Why do you not put bananas in the refrigerator?
Actually, you can put bananas in a refrigerator to help keep them from over-ripening. Some say refrigerating a banana changes its taste, but it is better than having it over-ripen or even rotting. The skin of a banana turns brown or black faster in the refrigerator, but the banana meat itself does not ripen that much more. In fact, it is recommended that ripened bananas be frozen to preserve them even longer. The cold temperature of a refrigerator encourages an enzyme (polyphenyl oxidase), which is naturally found in the banana, to polymerise phenols in the banana skin into polyphenols.

Do banana's ripen in the refrigerator?
Bananas ripen in a refrigerator, but they do so much slower than it left at room temperature. The skin of a banana turns brown or black faster in the refrigerator, but the banana meat itself does not ripen that much more.
