When it’s hot outside, your refrigerator works hard. You can help it perform more efficiently (and last longer) by regularly cleaning areas that impact airflow. Like your HVAC unit, your refrigerator draws air through condenser coils. The coils release heat to help cool the interior of the refrigerator. Here’s what they need to stay in great condition:
1. Many refrigerators have a plastic, louvered cover on the front bottom of the unit. Open the refrigerator doors and you should be able to remove the front cover.
2. Move the refrigerator away from the wall. UNPLUG the refrigerator. If you have an ice maker or water dispenser, be careful to avoid pulling the water line free. The back of the unit may have significant dust accumulation. Using either a soft vacuum brush or a soft cloth, remove the dust from the back of your refrigerator. If the dust is extremely heavy or if you haven’t ever cleaned the coils, you will need to remove the coil cover. Typically, there are screws on the cover. We always recommend taking a photo before removing any screws for future reference. Again, make sure your unit is disconnected from the plug. Once the coils are exposed, gently vacuum them to remove built-up dust. This helps your compressor operate efficiently and may reduce energy usage.
3. Clean dust and debris from underneath the refrigerator. This also contributes to reduced airflow.
4. Mark your calendar for three months out to repeat these simple tasks. If you keep dust off of the cover of your condenser coils, you won’t need to remove the cover every time. If your condenser coils overheat, this will lead to compressor failure over time which is a costly repair.
5. When you move your refrigerator back into its space, make sure there is open space on either side so air can circulate under and around the unit.

For added efficiency, consider using organized storage containers so air can flow freely inside your refrigerator. Your refrigerator should maintain a temperature between 35 degrees Fahrenheit and 38 degrees Fahrenheit. Freezers should be set to 0 degrees or lower.
