Money-saving tips to prevent your fridge from ‘overcooling’ and freezing your food

The refrigerator runs 24 hours a day, seven days a week in most households, putting a significant dent on your annual energy bill. While larger and older models use more electricity than newer or smaller appliances, the cost of running a refrigerator can increase significantly if it is not operating efficiently. According to a refrigeration expert, accidentally freezing items in your refrigerator can have several reasons, which are known to increase energy consumption. Fortunately, all of them can be prevented by doing just a few simple checks.

Although the freezer is the place where frozen items should be kept, accidentally freezing the refrigerator is actually quite common but few of us know why this happens.

According to Omar Idrissi, specialist at ADK Kooling, refrigerator items can freeze for “a plethora of reasons,” not just the temperature of the appliance.

He said: “Frozen food can be a minor inconvenience or a major frustration. It can cause your product to go bad or even cause compressed cans to pop open when the liquid freezes, a situation no one wants (clean up).”

Why is my refrigerator frozen?

The cold air in your refrigerator comes from the evaporator coils located behind the freezer compartment.

The refrigerator is a separate room, where cold stale air circulates through a gap between the two compartments.

Omar explained that in all refrigerators, a “damper” controls the size of the opening, while a fan controls circulation.

While both are controlled by a temperature-sensitive thermostat, other factors can still affect just how cold your refrigerator is.

The temperature setting is wrong

The most obvious cause of a deep-frozen refrigerator is an internal temperature that is too low.

This should always be the first thing to check if you’re having trouble keeping refrigerated food from freezing.

While some people naturally think they should set their fridge to the lowest temperature, the Government Food Standards Agency (FSA) has recommended that the optimum temperature for keeping your fridge is actually 5C and below.

Anything above that can be a breeding ground for some harmful bacteria, and anything below that can begin to affect the texture and quality of some foods.

Omar said: “If you can’t find the temperature controls on your fridge, you can use a thermostat to read the fridge.

“We recommend leaving it overnight for an accurate reading, especially if the fridge is opening and closing all day.”

The seals are broken

Keeping the refrigerator door closed is the only way to keep your refrigerator working properly, but just because the door is closed doesn’t mean it’s actually airtight.

Seals around refrigerator doors are another important area to check if you are experiencing freezing problems.

Omar explains: “Each domestic and commercial refrigerator door is fitted with a secure and protective seal to ensure that the refrigerator door closes completely – to maintain the internal temperature.

“If your refrigerator’s seal is damaged or missing, air can leak out, forcing the refrigerator to work even harder to stay cool – which will negatively affect your energy costs in the long run as more electricity is used. .”

Mold and even the smallest crack in door seals can be problematic, so it is always important to have them replaced as soon as possible.

The “coils” are dirty

Coils are part of all refrigeration and refrigeration equipment and play a vital role in its proper functioning.

In most cases, heat exchangers or condenser coils are visible on the outside of a refrigerator, while the evaporator coils are inside.

Omar said, “The cooling coils serve to act as a heat-exchanging medium between the coolant and its environment.

“If they get dirty and/or get covered in dust, the fridge has to work harder than usual to maintain the set freezing temperature.

“In some models, this can lead to overcooling, freezing everything.”

Unfortunately, there is no quick fix for this problem, so any repairs should be kept for a qualified service technician with proper training and equipment.

Regular cleaning can prevent this type of damage and also save you money on expensive repairs.
