Question

What reasons would cause a fridge/freezer to use more energy than expected? Our appliance uses more than double the yearly label kWh.

Answer 1

There are several factors that can cause a refrigerator or freezer to use more energy than expected, resulting in higher energy consumption than the stated label kWh. Here are some possible reasons:

1. Poor maintenance: Lack of regular maintenance, such as cleaning the condenser coils, can cause the appliance to work harder to maintain the desired temperature. Dust and debris accumulation on the coils can hinder heat transfer, leading to increased energy consumption.

2. Temperature settings: If the temperature settings on your fridge or freezer are lower than necessary, it will result in higher energy usage. Make sure the temperature is set to the recommended levels for food safety while still being energy-efficient.

3. Door seal issues: If the door seal or gasket is damaged or not properly sealed, cold air can escape from the unit, causing the compressor to run more frequently to maintain the desired temperature. Inspect the door seal and replace it if necessary.

4. Overloading: Overloading the refrigerator or freezer with too much food can obstruct airflow and make it harder for the appliance to cool efficiently. This can lead to increased energy consumption. Ensure that there is enough space around the items for proper airflow.

5. Location and ventilation: Placing the appliance in a location with poor ventilation, such as near a heat source or in direct sunlight, can make the compressor work harder to cool the unit, resulting in higher energy usage. Ensure that there is adequate space around the fridge/freezer for proper airflow.

6. Aging or inefficient appliance: Over time, the efficiency of refrigerators and freezers can decrease due to wear and tear. If your appliance is old or not energy-efficient, it may consume more energy than newer models.

If you're concerned about the energy consumption of your refrigerator or freezer, it may be worth considering getting it inspected by a professional technician. They can assess the appliance for any issues, provide maintenance recommendations, or advise on whether it's time to consider upgrading to a more energy-efficient model.
