A Guide to DIY Refrigerator Maintenance at Home: Keep Your Fridge Running Like New

1. Deep Clean Your Refrigerator Inside and Out

A clean refrigerator is the foundation of long-lasting performance. Over time, spills, food residue, and moisture build up inside your fridge, causing bad odors and bacterial growth.

Here’s how to deep clean your refrigerator like a pro:

Unplug the refrigerator and remove all food, drawers, and shelves.

Wash the shelves and bins with warm soapy water.

Clean the interior using a natural mix of baking soda and water. It removes stains and neutralizes odors.

Don’t forget the door gaskets (rubber seals): dirt here can stop doors from closing properly, letting cool air escape, and increasing energy usage.

Pro tip: Keep an open box of baking soda inside your fridge; it naturally absorbs odors and keeps your refrigerator smelling fresh.

2. Clean the Condenser Coils Regularly

The condenser coils are one of the most important parts of your refrigerator. These coils are usually located behind or underneath the fridge, and they help release heat during the cooling process.

When dust and debris cover the coils, the compressor has to work twice as hard to maintain temperature, leading to higher energy bills and early wear and tear.

To clean the coils:

Unplug your fridge and gently move it away from the wall.

Use a vacuum cleaner or a coil cleaning brush to remove accumulated dust.

Repeat this process every 3–6 months to maintain top performance.

3. Set the Right Temperature for Food and Efficiency

Setting the right temperature helps your refrigerator work smarter, not harder.

Here’s the sweet spot:

Refrigerator section: 3°C to 4°C (37°F to 40°F)

Freezer section: -18°C (0°F)

Avoid setting it too cold, not only does it consume more electricity, but it can also cause ice buildup and damage food texture.

If you have an older model without a digital display, invest in a fridge thermometer for accuracy. The right temperature improves efficiency, saves energy, and keeps your groceries fresh longer.

4. Inspect and Maintain the Door Gaskets

The door gasket (rubber seal) keeps cold air in and warm air out. If it’s loose or damaged, your refrigerator’s compressor will run continuously, wasting energy.

To test your seal:

Place a piece of paper or a currency note between the door and the frame.

Close the door and try to pull it out. If it slides out easily, the gasket isn’t sealing properly.

Clean the gasket using warm water and mild soap.

Replace it immediately if you notice cracks, wear, or looseness.

Pro tip: A tight door seal ensures better cooling and can save up to 15% on your refrigerator’s energy use.

5. Defrost the Freezer to Prevent Ice Buildup

If your fridge isn’t frost-free, regular defrosting is a must. Ice buildup reduces cooling efficiency and can block air vents.

Here’s the right way to do it:

Unplug the refrigerator and remove all food items.

Leave the door open to let the ice melt naturally.

Never use sharp objects to remove ice that can damage coils.

Once the ice has melted, wipe the interior dry before restarting.

Regular defrosting keeps your freezer running efficiently and prevents motor strain.

6. Position Your Refrigerator Correctly

Where you place your fridge has a big impact on its efficiency. Avoid positioning it near ovens, dishwashers, or direct sunlight, as heat forces the compressor to overwork.

Make sure there’s at least 2–3 inches of space between the fridge and the wall to allow proper airflow. Good ventilation keeps the motor cool and prevents overheating, one of the leading causes of refrigerator failure.

7. Watch Out for Unusual Noises

Your refrigerator is designed to run quietly, so if you suddenly hear buzzing, rattling, knocking, or humming noises, it’s a clear sign that something isn’t right. These sounds can indicate:

Loose or vibrating parts.

A blocked or dirty condenser fan.

An overworked or failing compressor.

Ice buildup around the evaporator motor.

If the noise is minor, try cleaning the fan area and tightening visible screws. However, if the sound continues or becomes louder, it’s best not to ignore it.

That’s where FAJ Technical Services L.L.C comes in. Our expert refrigerator technicians in Dubai can quickly inspect and diagnose the cause of the noise, whether it’s a worn-out compressor, motor issue, or fan problem. We provide professional refrigerator repair and maintenance for all brands and models, ensuring your appliance runs smoothly and quietly again.

8. Organize Your Fridge for Better Air Circulation

Keeping your refrigerator organized isn’t just about aesthetics it improves airflow and cooling efficiency.

Don’t overcrowd shelves; cold air needs space to circulate.

Store dairy at the back (the coldest area).

Keep fruits and vegetables in separate crispers.

Label leftovers and clean expired items weekly.

Organized storage helps your refrigerator maintain consistent cooling and prevents food from spoiling early.

Final Thoughts

Taking care of your refrigerator is easier than most people think. Small steps like cleaning the coils, checking the door seals, and keeping the right temperature can make a big difference. These simple habits help your fridge work better, last longer, and use less electricity.

However, not every issue can be fixed at home. If your refrigerator starts making strange noises, leaks water, or stops cooling properly, it’s best to get it checked by professionals.
