4 Common Fridge or Freezer problems

Fridges / freezers hold a high position in the hierarchy of household items in terms of importance and are at the heart of every home since they keep fresh foods like meat, fruits, milk and cold water readily available. Some of the foods stored in fridges constitute the basic needs that any home cannot do without thus making a functional fridge in every home a necessity.

Since refrigerators play such a pivotal role in the day to day lives of people, it goes without saying that knowing everything about your fridge is very important, which is what this article aims to do by exploring fridges in-depth. So, let’s dive straight into the heart of the matter starting by explaining what a refrigerator or fridge is.

What is a fridge?

A fridge is a commercial and home appliance consisting of a thermally insulated compartment and a heat pump that transfers heat from its inside to its external environment so that its inside is cooled to a temperature below the room temperature. 

How does a fridge WORK?

In the refrigeration cycle, there are five basic components: fluid refrigerant; a compressor which controls the flow of refrigerant; the condenser coils (on the outside of the fridge); the evaporator coils (on the inside of the fridge); and an expansion device. Here’s how they interact to cool your food.

1. The compressor constricts the refrigerant vapor, raising its pressure, and pushes it into the coils on the outside of the refrigerator.

2. When the hot gas in the coils meets the cooler air temperature of the kitchen, it becomes a liquid.

3. Now in liquid form at high pressure, the refrigerant cools down as it flows into the coils inside the freezer and the fridge.

4. The refrigerant absorbs the heat inside the fridge, cooling down the air.

5. Last, the refrigerant evaporates to a gas and then flows back to the compressor, where the cycle starts all over.

Benefits of a Fridge / freezer

Perishable foods stored at the wrong temperature will spoil, leading to changes in color, texture, and flavor. Refrigeration lowers the reproduction rate of bacteria, reducing the rate of spoilage. Eating food that hasn’t been kept at the right temperature increases chances of getting food poisoning which leads to death.

Some other benefits of fridges / freezer include:


Refrigerators provide a cooling solution to preserve food and other medicines in the home which are temperature sensitive from spoiling. When its hot fridges / freezers maintain temperatures that are just below the freezing point of water turning it into ice cubes to serve for an ice chilled drink and other purposes. Commercial fridges allow businesses to preserve floor shop stock at the right temperature delivering quality and fresh goods to customers.

Cost effective

Fridges come in different shapes and sizes but ultimately, they are cost effective. There is a fridge to suite every pocket on the market and the cost is negligibly compared to the huge benefit a fridge brings to the home. To put this into perspective, how long can food last without refrigeration? Not very long, and this leads to huge losses, stress and hunger when food is not readily available.

It’s important to have a functional fridge at all times which is why you should always be on the lookout for signs of a broken-down fridge and its associated symptoms. There are several common problems to look out for and let’s take a look them.
