Refrigerators
Does the light really go out when we close the door? From the early icebox to the modern built-in frost-free stainless steel double door works of art, refrigerators have improved greatly over the years, and we seldom think about them until they don't work right. From cleaning methods to repairs, this category is the place to get advice and answers to your questions about refrigerators.

How does a fridge door stay shut?
A fridge door stays shut primarily due to the magnetic seal around the edge of the door, which creates a strong enough force to keep it closed. This seal is designed to prevent warm air from entering and cold air from escaping, helping maintain the desired temperature inside the fridge. Additionally, the design of the door itself often includes hinges and a latch mechanism to secure it in place.
Blood should be stored in a refrigerator and maintained at what temperature?
Blood should be stored in a refrigerator and maintained at a temperature between 1 to 6 degrees Celsius. This temperature range helps to preserve the integrity and viability of the blood components for transfusion.
How much does a refrigerator door weigh?
The weight of a refrigerator door can vary depending on the size and material of the door. On average, a refrigerator door can weigh between 15 to 30 pounds.
What in a refrigerator prevents bacteria and fungi to come on the food?
The cold temperature of the refrigerator slows down the growth of bacteria and fungi on food, reducing their ability to multiply and spoil the food quickly. Additionally, the sealed environment of the refrigerator helps to minimize exposure to outside contaminants that could introduce bacteria and fungi to the food. Regular cleaning and maintenance of the refrigerator also help to prevent the buildup of harmful microorganisms.
What happens to the air when you open a refrigerator door?
When you open a refrigerator door, warmer air from the room enters the refrigerator and mixes with the cooler air inside. This can cause the temperature inside the refrigerator to slightly increase as it works to re-establish the set temperature. The refrigerator then expels this warmer air through its coils to maintain the desired temperature.
What would you expect a balloon filled with air if it was put into a refrigerator?
It would get smaller. The gas particles would cool down and contract. And if you put it outside in the sun, the gas particles would heat up and expand. I just learned this in science, so... Hope this helped!
Does a refrigerator have a regular plug?
In USA, Canada - and other countries where a 60 Hz standard electricity supply service is used - small air-conditioning units, intended for mounting below windows, are available for use on regular 110 - 120 volt outlets. They use either up to 1,800 watts or up to 2,400 watts.
A North-American 120 volt receptacle (socket outlet) is a 'duplex' (twin) outlet with a combined rating of 15 amps unless a link arrangement at the back of the receptacle is broken, in which case, the two 'halves' of the receptacle would be supplied from individual 15 amp circuits from the supply panel, allowing 15 A each.
The design of the duplex receptacle is such that the two outlets are arranged vertically. Because of this, both outlets can only be used simultaneously if appliances having cables fitted with "in-line" plugs are used.
If a grounded 3-pin plug with a cable exiting from it at 90-degrees (like British 13 amp plugs) is fitted to the cable of a relatively high-current appliance - such as an air-conditioner unit - then only one such appliance can be used if it is plugged into one of the duplex receptacles because the appliance's cable covers the other receptacle!
For this reason, air-conditioning units are supplied with cables whose plug is at right-angles to the cable (called an 'AC cable') - meaning that only ONE receptacle outlet can be used.
That scheme prevents the duplex outlet from becoming overloaded (i.e. exceeding 15 A).
So, the simple answer is that an AC unit can only be used with a normal 120 volt 15 amp receptacle if it is connected with an AC cable and not a regular cable ("'regular" meaning a cable with an in-line plug). Otherwise, there is the possibility of overloading the receptacle.
To be able to let the sales person know which kind of air-conditioner you want - so that you don't buy a unit that would overload your wiring - before you buy one it is best to find out for sure if the regular outlet you want to plug it into can safely support a continuous current draw of 15 amps - as would be the maximum amperage used by 1,800 watts 120 volt air conditioning units - or 20 amps, as would be the maximum amperage taken by the 2,400 watts 120 volt units.
Safety Warning
If you use one of those small air-conditioners you must take care not to overload the house wiring by using any other large home appliances plugged into other receptacles that are wired into the same circuit.
Using a small electric light, hi-fi unit or television may be ok, but don't try to use a powerful hair dryer or vacuum cleaner at the same time as the air-conditioner is running.
Most likely the resulting current overload would cause the circuit breaker to trip - to cut off the power before anything catches on fire - but it is wiser not to do it!
Note: Large air-conditioners take a lot more power so they can only be used on a 240 volt branch circuit. (It must have the right kind of outlet, wiring and circuit breakers for 240 volts.)
An earlier answer that does not really answer the actual question:
Air-conditioners are devices with higher consumption of electricity
if it is plugged in a normal house plug it will intake large amount of current which will pass through Power Meter and the filament (element) present in it will burn out. (No, it is the house wiring which might catch on fire if the circuit breaker failed to trip to cut off the current.)
This may even affect the internal wire connections..which may cause fire due to electrical sparks.It is highly dangerious to plug it in plug. (???)
If, over the next 7 days, no changes are made to improve the above earlier answer, it will be moved over to the Discussion page.
How would a refrigerator be measured in metric weight?
A refrigerator would typically be measured in kilograms (kg) in terms of weight in the metric system.
Why does a refrigerator start making more noise?
A refrigerator may start making more noise due to issues such as a buildup of dust and debris on the condenser coils, a malfunctioning fan, or a failing compressor. Regular cleaning and maintenance can help prevent excessive noise.
Who invented the refrigerator and in which year?
In the yr 1876.reigerator was invented by carl paul gottfried von linde.bt there practicle use in homes starts from 1911.....
What metal is a washing machine body made from?
If you mean the part of the dishwasher other than the door, it's made of either plastic or stainless steel (whatever the inside is made of, that's the same as the outside). If you mean the door, either painted steel or stainless steel.
What component of a refrigeration system changes a high pressure vapor to a high pressure liquid?
The condenser is the component of a refrigeration system that changes high-pressure vapor into high-pressure liquid by transferring heat to the surrounding environment. This process involves the conversion of refrigerant from a gas to a liquid state by releasing heat to the outside air or water.
Would butter cheese or fish be the coldest in a fridge?
Assuming they've all been in there long enough to equilibrate, and assuming you haven't put them in some "special" location that's colder or warmer than average (the shelves in the door, for example, are often slightly warmer than the main shelves), they will all be the same temperature.
Why did William Cullen invent the refrigerator?
William Cullen did not invent the refrigerator. The first practical refrigerator was invented by Oliver Evans in 1805. Refrigerators were developed to preserve food and extend its shelf life by keeping it cool.
What if your refrigerator is 5.6 amps so how much does it cost you a month at 22 cents per kilowatt?
A refrigerator is not on all the time. It is controlled by a thermostat that keeps it at a certain temperature. To answer this question the total number of hours the refrigerator was actually running would have to be recorded. Knowing this information and the voltage at which the refrigerator operates a calculation could be made.
How does a refrigerator freezer remove thermal energy?
thermal energy never disappears but, it can be moved from one place to another which what a refrigerator does. on the back of a refrigerator there are heat exchange tubes which get hot as they pump heat from the interior to the exterior of the refrigerator.

Is a common temperature of a fridge below freezing point?
No.. otherwise water would turn to ice when in a fridge.. i don't think that happens too often ;) My fridge thermometer instruction sheet recommended 44 deg. F as the optimum temp for lower shelves.
What problem did the refrigerator solve?
Food does not go bad anymore, meaning food can be stored, meaning that more food could be made because more would be wasted, meaning agriculture benefited from the fridge, and so did companies that make the fridge. +1 point for capitalism.
Kilograms.
liters is mot a mass unit but a volume unit so that cannot come into discussion at all.
The only difference between milligrams, grams and kilograms is that 1000 milligrams makes 1 gram and 1000 grams makes 1 kilogram. so you can of course measure the weight of a refrigerator in milligrams but you would have a value in the tens of millions.
Can a refrigerator get colder by installing a lower temp thermostat?
In basic theory yes it would get colder by installing a lower temp thermostat.
However the common household refrigerator was not designed for that application,..most household Units set at the lowest temp can cool down to about 35*F in the refrigerator section,and 20-28*F in the freezer section... putting in a lower temp thermostat may cause the unit to run constantly as it tries to achieve the lower temp settings and If your unit runs constantly your electric bill will skyrocket and I would estimate that within 3-7 days of constant running you would either burn out a thermal overload or the compressor unit...
Refrigerators are cold because they use a refrigeration system that removes heat from the interior to lower the temperature. The refrigeration system consists of a compressor, condenser, expansion valve, and evaporator working together to circulate refrigerant, absorbing heat and cooling down the interior of the refrigerator.
Can a Refrigerator be next to a heat water heater?
It is not recommended to place a refrigerator next to a hot water heater. The heat from the water heater can affect the refrigerator's cooling system, causing it to work harder and potentially reducing its efficiency. It is best to keep appliances like refrigerators away from sources of heat to ensure they operate effectively.
A whole house filter is normally a terrible waste of money as why filter water to be used for flushing toilets?
Ans 2 - The first answer does not have relevance to the question.
Your refrigerator has it's own inline filter. -It appears that it's time to change it. -This is generally quite simple and the filter can be bought at any appliance parts store. Be sure to have the make, model and ser # when buying this (or any appliance parts )
Why is the outside of a fridge white and shiny?
The outer surface of a fridge is typically white and shiny to reflect light and heat, which helps keep the fridge cooler by preventing heat absorption. The white color also helps to easily spot dirt or stains for cleaning.
What will be happening if you remove a magnet from a fridge door?
well it depends on the magnet is it strong or not
