Finding the Perfect Solution. The optimum amount of food to fill in the fridge is three-quarters full. At this amount, there's enough space for the air to circulate freely inside and, at the same time, sufficient food to help each item cool its neighbour down.
Fridge temperature settings are generally numbered from 1 to 5, with 5 being the coldest. A fully stocked fridge may need to be set to a higher setting (around 3 or 4), whereas one with more space is best suited to temperature setting 2 or 3.
Don't overfill your fridge. Inside your fridge the cold air needs to be able to circulate, as this is how it keeps the food chilled throughout. If your fridge is crammed full, the unit has to work even harder to make sure the air can circulate.
You can expect a standard fridge to stick out about six inches past the edge of the counter. While it doesn't seem like much, these six inches can be just enough to disrupt the kitchen work triangle. If you have a kitchen island in front of your fridge, these six inches can mean a lot of space.
A fuller fridge has less air to keep cool, so doesn't have to work quite as hard as a sparsely populated appliance. When sufficiently loaded, items help keep each other cool. You should be able to keep your refrigerator at least 2/3 full.
The Dangers of Fridge Overfilling
As a result, the fridge is going to have to work harder to cool everything down. Having too much food in your fridge doesn't just cause it to work harder, but it could also lead to blocked vents, which can damage your fridge.
Keep it stocked. A full fridge is a happy fridge because the thermal mass of its contents helps maintain the temperature (or in other words, the cold stuff helps keep it cold). In a full fridge, the compressor won't need to cycle on and off as much, which will extend the life of the compressor and reduce running costs.
Counter-depth refrigerators are about 24–25 inches deep, approximately the same depth as kitchen counters. While counter-depth fridges are virtually flush with counters and cabinets, standard-depth refrigerators are typically 30–36 inches deep and can stick out half a foot or more past countertops.
There should also be a space of 1-2 inches on the back of the fridge to allow proper air circulation. Newer refrigerator models have their coils at the back so leaving space is imperative to have proper ventilation. On each of the sides, there should be a space of 1/2-1 inch.
It is important to leave your fridge to settle after moving to protect the appliance's internal parts and to ensure that the fridge continues to work to maximum efficiency. When moving a fridge, the compressor oil can leak into the refrigeration system, causing a blockage if the appliance is turned on too quickly.
Another common cause of compressor failure is a build-up of dirt and dust. This can happen if the fridge isn't cleaned regularly or if there's a lot of dust in the air. Over time, the dirt and dust can clog up the compressor, causing it to overheat and break down.
While it's recommended to fill your refrigerator rather than letting it be relatively empty during its operation, it's crucial that you avoid overfilling your refrigerator with too many supplies. Overcrowding affects the air vents, resulting in poor air circulation and higher energy consumption.
OVERPACKING
If your freezer is not working, the first thing to check is if the shelves are packed too tightly. Overstuffed freezers can cause an airflow blockage, especially when the evaporator fan is blocked. If your freezer is not cold enough, try clearing off your freezer shelves.
The amount of food that you have inside your refrigerator does matter to its efficiency. An empty refrigerator doesn't stay cool as easily as one that has the right amount of products inside, while a refrigerator that is too full won't cool the contents as easily.
Understanding the Numbers on the Dial
The numbers on the temperature control dial generally represent a range of temperatures rather than specific degrees. Typically, a lower number (e.g., 1 or 2) corresponds to a warmer setting, while a higher number (e.g., 6 or 7) indicates a colder setting.
The ideal fridge temperature is between 0°C and 5°C.
However, the average temperature of fridges in the UK is 7°C! This means that a lot of people have their fridge temperature set too high.
Without adequate ventilation, the refrigerator can overheat, and the unit may display immediate symptoms or slowly deteriorate over the course of time with issues that may include: Insufficient cooling. Unusual or loud operation. Excessive rise in energy costs.
Keep the fridge at 5°C or below.
Use a mercury-free fridge thermometer on the bottom shelf above the salad drawer for an accurate reading. Keep the fridge door closed. The temperature will rise if the door is left open for any length of time. Don't put hot food in the fridge as this can also raise the temperature.
If you don't allow enough space, the fridge will have to work harder to stay cool, which could shorten its lifespan and will definitely cost you more in electricity bills. "We generally recommend allowing at least 5cm on each side, 10cm on top and 5cm at the rear," says Ashley.
The refrigerator will need minimum clearances of 2 inches from the back wall, 1-inch from the upper cabinet and 1/8-inch on either side of the fridge. This will allow air to circulate around the box so the fridge runs efficiently and doesn't overheat.

If it is transported upright, wait at least two to three hours before plugging it in. If transported on its side, turn it upright and let it stand for at least four hours.
Storage tip: Keep your freezer full, but not packed. Keeping your freezer around 75-80% full helps retain cold air. If the freezer is fully filled, food may block the internal air vents, making it harder to distribute cold air throughout the freezer.
“A full refrigerator doesn't decrease energy use,” says researcher Jacob Talbot of the nonprofit American Council for an Energy-Efficient Economy (ACEEE). Your fridge's foodstuffs most likely don't displace enough space to reduce the amount of energy needed to keep it chilled, he explains.
Also, when putting food away, don't crowd the refrigerator or freezer so tightly that air can't circulate. 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).
