Can a Freezer Be Used as a Fridge and What to Consider

If you're considering using a freezer as a fridge, it's essential to understand the differences between the two appliances. Freezers are designed to keep food at 0°F (-18°C) or below, which is much colder than a fridge's typical 40°F (4°C) temperature.

The main issue with using a freezer as a fridge is that it's not designed to store food at the right temperature for a long time. According to the article, freezers can only keep food at a safe temperature for a few hours, not days. This means you'll need to constantly add and remove food to maintain a safe temperature.

Freezers also tend to be more humid than fridges, which can lead to ice buildup and affect the quality of your food. In fact, the article notes that freezers can have a humidity level of up to 80%, compared to a fridge's 50-60%.

The magic of converting a freezer into a fridge lies in the way it works. The compressor hardly needs to do any work to keep the contents cold when the temperature inside the freezer is raised to that of a refrigerator.

This is because the compressor only needs to switch on for a few minutes each hour, unlike a regular fridge where it might be on for around 20 to 30 minutes per hour. This makes the converted freezer a very energy efficient refrigerator.

Cold air sinks, so each time you open a 'chest refrigerator' virtually no chilled air is lost. This is a big advantage over regular fridges, where you often lose cold air when you open the door.

The thermostat plays a crucial role in this conversion. You need to carefully unravel the new thermostat's capillary tube and insert it into the freezer through the same slot that you just removed the old one. Be careful not to bend or kink the wire – it's fragile.

The new thermostat needs to be installed in the old housing, and you should add the adjustment dial back on. Place the adjustment dial at its mid point for a temperature of about 4 degrees. If your freezer has a ‘Fast Freeze’ switch, make sure you turn it off.

Once you've completed these steps, turn the power back on and you'll have a very energy efficient refrigerator!

Converting a freezer into a fridge is a relatively straightforward process, but it does require some technical know-how.

First, you'll need to unplug the old thermostat and plug in and mount the new one. No actual wiring, crimping, or soldering is required, but if you're not confident in completing this upgrade, it's best to seek the assistance of a qualified tradesperson.

To start, turn off the freezer at the wall and unplug the power cord. This is an important safety precaution to prevent any accidental electrical shocks.

Locate the thermostat housing and take note of how the existing thermostat is wired. You'll need to remove it and slowly pull the capillary tube wire out of the freezer.

The thermostat is basically a switch between the power outlet and the compressor, and it won't matter if the 'Active' and 'To Compressor' wires are reversed - it will still work.
