Refrigerator care and maintenance

To protect and maintain the mini fridge well, you should pay attention to the following issues:

Plug the refrigerator directly into the socket

You ought to plug the refrigerator directly into the electrical outlet, avoiding plugging through the wire. However, in case of necessity, make sure to use a heavy-duty extension cord that meets the amperage of the device and that it is properly grounded.

Place the fridge away from heat sources

It is important to install the refrigerator away from heat sources such as radiators, stoves, or windows with direct sunlight. This helps to ensure that the airflow of the compressor and cooling coils is not blocked or restricted.

Keep the inside of the cabinet clean

Ideally, you should clean the refrigerator once a month. When cleaning the refrigerator, it is better to remove all food as well as the shelves. Then, use a mild detergent or baking soda to dissolve the water, and wipe the inside with a soft, damp cloth to remove soap or baking soda residue.

Alternatively, you can also clean the rack and plastic parts in the same way. However, during cleaning, make sure not to put the glass parts in hot water as they may break. Furthermore, try to avoid using any corrosive cleaners so that the glass won’t get scratched.

Avoid odors

For fresh foods, when you put them in the refrigerator, you should cover and wrap them carefully to avoid the food from drying out and having a special smell. If food is spoiled, be sure to remove it immediately to prevent odors from settling on your refrigerator.

Don’t put too much in the refrigerator

The refrigerator should not be too full.  With a limited capacity, overfilling prevents the circulation of cold air used to regulate temperature. So this can lead to heat spoilage due to inconsistent temperature.
