What temperature is normal?
Refrigerators should have a temperature of 4–8˚C. As the temperature decreases by one degree the power consumption increases by approximately 10 percent. Cold cabinets should be slightly warmer and have a temperature of 8–12˚C. The freezer should be about -18 to -20C.
Keep it cool:
- Thaw frozen foods in the refrigerator instead of the microwave – it will help the refrigerator stay cool and use less energy while thawing the food.
- Let food cool down before refrigeration. If you put hot food in the fridge it heats up the food that is already in there.
- Pack the frozen foods tight. This will help them last longer and will require less energy to stay frozen.
- An empty refrigerator or freezer uses more energy than a well-stocked one.
- Do not keep the freezer or refrigerator door open longer than is necessary.
- Defrost refrigerators and freezers regularly.
- Vacuum the back of the refrigerator and freezers.
When ice builds up in refrigerators and freezers they use up more energy to stay cold. So it helps to defrost the freezer regularly. The same goes for the refrigerators that are not self-defrosting.
How to defrost:
- Empty refrigerators and freezers.
- Turn off the electricity with the button located inside the refrigerator and freezer. Look in the manual if you are unsure.
- Leave the door open and let the ice thaw by itself. Do not use a knife or sharp objects or you may risk puncturing the delicate tubes inside which will result in the gas escaping. Tenants in the past have had to pay for a new freezer because of damages like this.
- Set a bowl close to the refrigerator and freezer so that water does not run out on the floor.
- The tubes that are behind or under the refrigerator or freezer are there for dissipating heat. Cleaning and vacuuming near these tubes will keep them working effectively and keep energy consumption down. Sometimes when a refrigerator or freezer doesn’t cool down, all that is needed is to clear the tubes from dirt and dust buildup.
