The global market for refrigerators and freezers was worth a whopping $81.90 billion in 2020.

That proves just how integral to life fridges and freezers have become. After all, without them, we’d still be preserving food through salting or smoking.

However, even though fridges have been around for over a century now, myths about them still exist. We listed and debunked some of the top ones in this guide, so be sure to keep reading.

Lower Thermostat Number Means Colder Interiors

This myth is more common among older fridges, which have dials or knobs for thermostats. These dials control the temperature within the device with a numbering system, such as 1 to 5.

Some people think that the lower the number, the colder the fridge will be.

Those numbers don’t translate to actual temperatures; they pertain to certain temp levels. The lower the number, the higher the temperature within the fridge.

It’s imperative to keep your fridge temp below 40 °F, as this is where the food danger zone starts. Many types of bacteria grow at a rapid rate within temperatures of between 40 °F and 140 °F.

It’s Okay to Always Pack the Fridge Full of Food

Overloading your refrigerator with stuff like leftover meals can hinder its cooling capacity. For example, food containers can block the airflow within the fridge. This can lead to inefficient cold air circulation, so some sections of the fridge won’t get cold.

When that happens, the inadequately chilled spots can become food danger zones.

Leftovers in the Fridge Keep for a Long Time

Health experts say that leftover meals stored in the fridge are okay to eat within three to four days. Any longer than that, and they can already be full of bacteria that can cause food poisoning.

For that reason, it’s best to eat leftovers as soon as the next day or two. It’s also a smart practice to label them with dates to help you remember up to when it’s safe to eat them.

There Are Only a Few Reliable Refrigerator Brands

General Electric (GE) and Whirlpool are two of the most popular refrigerator makers in the US. A primary reason for this is that both have been around for over a century now. GE’s founding took place in 1892, while Whirlpool’s establishment occurred in 1911.

Those two are still leading brands, but they’re not the only ones that make the best refrigerators. For example, according to, Samsung now ranks high, too. So much so that it’s now closely competing with Whirlpool.

LG, Panasonic, Hitachi, and Haier have also made names for themselves in the fridge sector.

All Refrigerators Consume a Lot of Energy

Refrigerators do use a considerable amount of energy, but some new units use much less. For example, Energy Star certified units can be up to 9% more energy efficient than other models.

As such, go with an Energy Star model if you want to invest in an energy-saving refrigerator. These have powerful refrigeration capacities but use less energy during their operation.

Time to Stop Believing These Refrigerator Myths

Please keep in mind that foodborne illnesses affect at least 48 million people in the US each year. Many of these are a result of eating food rendered unsafe by the danger zone.

That’s why it’s imperative to learn the truth about how refrigerators work. This way, consumers can develop proper and safe food storage and refrigeration practices.
