Your refrigerator works hard 24/7 to keep your food fresh and safe. But just like any hardworking appliance, it needs a little TLC to continue running efficiently and avoid costly repairs. While many Northern VA and DC homeowners know to clean the coils and check the temperature settings, there are lesser-known maintenance tips that can make a big difference in your fridge’s performance and lifespan.

Here are 10 refrigerator maintenance tips that go beyond the basics to help you protect your investment and keep things running cool.

Maintenance Tip #1. Check Door Gasket Alignment

The rubber gasket around your fridge door can loosen or warp over time. A misaligned or weak gasket allows cold air to escape, forcing your fridge to work harder. Run your hand around the edges to feel for escaping air or close the door on a dollar bill, if it slides out easily, the gasket may need cleaning, repositioning, or replacing.

Maintenance Tip #2. Level Your Refrigerator

If your fridge isn’t level, the doors may not seal properly, and the compressor may strain over time. Use a level to make sure the unit is sitting evenly. Slightly tilting the fridge back (front higher than the back) can also help doors close more securely on their own.

Maintenance Tip #3. Keep the Fridge at Least Two-Thirds Full

Your refrigerator operates more efficiently when it has enough thermal mass (i.e., food and drink). A fridge that’s too empty will lose cold air more quickly when opened. If you’re running light on groceries, fill containers with water to help maintain consistent temperature.

Maintenance Tip #4. Clean the Drain Hole and Drip Pan

Most fridges have a drain hole and drip pan to manage condensation. Over time, these can clog or mold. Clean the drain hole using a pipe cleaner or cotton swab, and check the drip pan under the unit for standing water or grime.

Maintenance Tip #5. Use Baking Soda or Fridge Deodorizers, but Change Regularly

Many people place a box of baking soda in the fridge, but forget to replace it. An old, saturated deodorizer won’t do its job. Replace it every 30–60 days and place it near the air vent where air circulates the most.

Maintenance Tip #6. Check for Ice Buildup in Unusual Places

Even frost-free models can sometimes build up ice in crevices around the air vents or behind panels, especially if the defrost drain clogs. Unexplained noises or poor cooling can be a sign. If you spot frost in odd areas, consider calling a technician to check the defrost system.

Maintenance Tip #7. Keep Items Away from Vents

Stacking food or containers too close to interior air vents restricts airflow and can create warm or frozen spots. Leave a few inches of space around vents to allow proper circulation, especially in the back of the fridge.

Maintenance Tip #8. Use a Fridge Thermometer

Even if your fridge has a digital display, it’s a good idea to place a simple thermometer inside to verify temperature accuracy. The fridge should be at or below 40°F, and the freezer should be at 0°F. Inaccurate readings could mean a faulty sensor or thermostat.

Maintenance Tip #9. Avoid Hot Foods

Putting hot leftovers straight into the fridge raises the internal temperature and forces the compressor to work overtime. Let hot food cool to room temperature first, or store it in smaller containers to cool more quickly and evenly.

Maintenance Tip #10. Vacuum the Toe Grille

Most people remember to clean behind or under their fridge, but the front toe grille at the bottom often gets overlooked. Dust, pet hair, and debris can block airflow to the condenser coils. Remove the grille (usually snaps off, but check first), and we recommend to vacuum or wipe clean every 3–6 months.

Bonus Tip: Schedule a Professional Checkup for Your Refrigerator

Even with diligent maintenance, an annual inspection by a professional technician can catch hidden issues before they lead to breakdowns.
