Can A Freezer Be Used As A Refrigerator?

To use your freezer as a refrigerator, you need to replace the existing thermostat with a refrigerator thermostat, which will allow you to set a higher temperature for your freezer. You also need to keep the door closed as much as possible and monitor the temperature regularly.

How to convert a freezer into a refrigerator

The main challenge of using a freezer as a refrigerator is how to prevent the food from freezing. A freezer is designed to maintain temperatures below 0°F (-18°C), while a refrigerator typically operates at around 40°F (4°C). If you simply plug in your freezer and turn the dial to the lowest setting, you may still end up with frozen food and wasted energy.

The solution is to replace the existing thermostat, which controls the temperature of the freezer, with a refrigerator thermostat, which will allow you to set a higher temperature for your freezer. A thermostat is a device that senses the temperature inside the appliance and turns the compressor on or off accordingly. By using a refrigerator thermostat, you can regulate the temperature of your freezer within the range of a refrigerator.

There are two ways to replace the thermostat:

• Buy a freezer-to-fridge conversion kit, which consists of a refrigerator thermostat, a temperature probe, a mounting bracket, and spare connectors. You can find these kits online for around $30 or less¹. To install the kit, you need to follow these steps¹:
  • Turn off and unplug your freezer.
  • Remove the existing thermostat by unscrewing it from its bracket and disconnecting its wires.
  • Connect the new thermostat by matching its wires with those of the old one and using the connectors provided.
  • Mount the new thermostat on the bracket and secure it with screws.
  • Insert the temperature probe into the freezer compartment and attach it to the wall with tape or glue.
  • Turn on your freezer and adjust the temperature according to its storage capacity.
• Buy an external plug-in thermostat, which comes with a metal capillary tube that acts as a temperature probe. You can find these thermostats online for around $60 or less². To install this thermostat, you need to follow these steps²:
  • Turn off and unplug your freezer.
  • Plug the external thermostat into the freezer outlet and plug the freezer into it.
  • Insert the capillary tube into the freezer compartment and attach it to the wall with tape or glue.
  • Turn on your freezer and adjust the temperature according to its storage capacity.

What are the benefits and drawbacks of using a freezer as a refrigerator?

Using a freezer as a refrigerator has some advantages and disadvantages that you should consider before making the conversion. Here are some of them:

Benefits

• Energy efficiency: A freezer has more insulation than a refrigerator, which means it can keep the cold air inside better and reduce heat loss. This translates into less energy consumption and lower electricity bills. According to some sources³⁴, using a freezer as a refrigerator can save up to 75% of energy compared to using a standard or counter-depth refrigerator.
• Space optimization: A freezer has more storage capacity than a refrigerator, which means you can fit more food and beverages inside. This is especially useful if you have a large family or like to buy in bulk. You can also choose from different sizes and configurations of freezers, such as chest, upright, bottom-freezer, top-freezer, column, or drawer.
• Food preservation: A freezer can maintain lower temperatures than a refrigerator, which means it can preserve food freshness and quality longer. This can prevent food spoilage and waste and extend the shelf life of your food.

Drawbacks

• Cost: A freezer is more expensive than a refrigerator, both in terms of initial purchase price and installation cost. You also need to buy an extra thermostat or kit to make the conversion, which adds to the expense. Moreover, if you have an old or inefficient freezer model, you may not save as much energy or money as expected.
• Flexibility: A freezer is less flexible than a refrigerator in terms of design and functionality. It is designed to fit into specific spaces and dimensions that may not suit your kitchen layout or preferences. It is also harder to move or replace if needed. Furthermore, it may not have some features that a refrigerator has, such as water and ice dispensers, smart connectivity, or touchscreens.
• Availability: A freezer is less available than a refrigerator in terms of options and variety. It has fewer choices in terms of brands, models, features, and prices. It may also have longer delivery times or limited warranties.

Tips and precautions for using a freezer as a refrigerator

If you decide to use your freezer as a refrigerator, here are some tips and precautions to follow to ensure optimal performance and safety:

• Keep the door closed as much as possible to prevent cold air from escaping and warm air from entering. This will help maintain a stable temperature and save energy.
• Monitor the temperature regularly with a thermometer to make sure it is within the safe range of 34°F to 40°F (1°C to 4°C). Adjust the thermostat accordingly if needed.
• Organize your food by type and expiration date to reduce waste and spoilage. Use containers, baskets, or trays to separate different items and make them easier to access.
• Clean your freezer regularly to prevent odors, mold, or bacteria from building up. Wipe the interior and exterior with a damp cloth and mild soap. Defrost your freezer if there is more than 1/4 inch of frost buildup.
• Contact a qualified technician if you encounter any problems or issues with your freezer or thermostat. Do not attempt to repair or modify them yourself.

Using a freezer as a refrigerator is a possible and practical way to repurpose an extra appliance and save energy and money. However, it requires some modifications and adjustments that may not be suitable for everyone. By following the instructions and tips in this post, you can make an informed decision and enjoy the benefits of your freezer-turned-fridge.
