The coils of your refrigerator play an important role in its operation. They help release the heat that the appliance absorbs from inside, allowing the fridge to maintain a cool temperature. Over time, dirt, dust, and debris can accumulate on the coils, causing your refrigerator to work harder and less efficiently. Cleaning your refrigerator’s coils regularly can extend its lifespan and improve its energy efficiency. Here's how to clean and maintain your fridge's coils for optimal performance.

1. Unplug the Refrigerator

Before you start cleaning, always unplug the refrigerator to avoid any electrical hazards. This also ensures the appliance is not running while you work on it, which can save energy and protect the internal components.

2. Locate the Coils

Refrigerator coils are typically located either at the back or underneath the fridge. The location depends on the make and model of your appliance.

• For coils at the back: You can simply pull the refrigerator away from the wall to access the coils.
• For coils underneath: You will likely need to remove the grill or cover at the bottom of the fridge to expose the coils.

3. Vacuum the Coils

One of the most effective ways to clean the coils is by using a vacuum cleaner with a brush attachment. Start by gently vacuuming any visible dust or debris on the coils. Be careful not to damage the coils with the vacuum hose or brush.

• Tip: Use a crevice tool to reach tight spaces if your coils are located underneath the fridge.

4. Use a Coil Brush

In addition to vacuuming, you can use a specialized coil cleaning brush to dislodge any stubborn dirt. These brushes are designed to get between the coils and clean areas that a vacuum cannot reach.

• How to use the brush: Gently run the brush along the coils, working in a back-and-forth motion. Make sure to clean both sides of the coils if possible. If the coils are in a tight spot, be patient and work slowly to avoid bending them.

5. Clean the Surrounding Area

While you're cleaning the coils, take the opportunity to clean the area around the fridge as well. Dust and dirt can build up around the appliance, which may block airflow and affect its efficiency. Use a damp cloth or a dry dusting cloth to wipe the surrounding floor and walls.

6. Check for Blockages

While cleaning, check for any blockages around the coils. If you notice a buildup of dust, dirt, or pet hair, this could be causing the refrigerator to run longer than necessary. Ensuring proper airflow is essential to the appliance's function.

7. Reassemble and Plug in the Refrigerator

After cleaning the coils, replace the grill or cover, if applicable, and plug the refrigerator back in. Move the appliance back into its place against the wall and ensure it’s level for proper operation. Monitor the fridge to ensure it’s running properly.

8. Maintain Regular Cleaning

For continued efficiency, aim to clean the coils every 6 to 12 months, depending on how much dust and debris your fridge is exposed to. If you have pets, you may need to clean the coils more frequently due to hair buildup.

9. Signs That Professional Help Is Needed

While cleaning the coils can solve many refrigerator problems, sometimes other issues may arise. If your refrigerator is still running inefficiently after cleaning, it could be due to more serious problems, such as a faulty compressor, thermostat, or evaporator fan. In these cases, it’s time to call an expert.
