Your refrigerator works 24 hours a day, 7 days a week — making it the hardest-working appliance in your home. Yet most homeowners don’t think about maintaining it until something goes wrong. The good news? A few simple habits can add years to your fridge’s life and save you hundreds in repair bills.
Here are 5 proven tips to keep your refrigerator running like new.
Tip 1: Clean the Condenser Coils Every 6 Months
Dirty condenser coils are one of the top reasons refrigerators break down early. These coils — usually located at the back or underneath your fridge — release heat from the refrigerant. When they’re clogged with dust and pet hair, your compressor has to work overtime, leading to overheating and early failure.
How to do it: Unplug the fridge, locate the coils, and use a coil brush or vacuum to gently remove buildup. It takes less than 15 minutes and can significantly extend the life of your compressor.
Tip 2: Check and Replace the Door Gaskets
The rubber seal around your refrigerator door (called a gasket) is responsible for keeping cold air in and warm air out. A worn or cracked gasket forces your fridge to run constantly to maintain temperature — spiking your electricity bill and wearing out the compressor.
Easy test: Close the door on a dollar bill. If you can pull it out easily, your seal is failing.
Fix it: Clean gaskets monthly with warm soapy water. If they’re cracked or no longer flexible, replace them — it’s an inexpensive fix that makes a huge difference.
Tip 3: Keep It at the Right Temperature
Many people set their refrigerator too cold thinking it will keep food fresher. In reality, incorrect temperature settings stress the appliance unnecessarily.
- Refrigerator: 35°F to 38°F (1.7°C to 3.3°C)
- Freezer: 0°F (-18°C)
Running colder than needed wastes energy and puts strain on the motor. Use an inexpensive appliance thermometer to double-check — your fridge’s built-in dial isn’t always accurate.
Tip 4: Don’t Overfill (or Underload) Your Fridge
Believe it or not, how much food you keep inside matters. An overpacked fridge blocks airflow, making it harder to maintain even temperatures. But an almost-empty fridge also struggles — there’s not enough thermal mass to hold the cold when the door opens.
The sweet spot: Keep your fridge about 75% full. If it’s frequently empty, store pitchers of water inside to help maintain a stable temperature.
Also make sure nothing is blocking the internal air vents — a bag of leftovers shoved against the back wall can disrupt the entire cooling system.
Tip 5: Schedule Annual Professional Maintenance
Even if your fridge seems to be running fine, an annual check-up from a qualified appliance repair technician can catch small problems before they become expensive ones. A technician will inspect the compressor, test refrigerant levels, check the thermostat, and ensure all components are running efficiently.
Think of it like an oil change for your car — it’s far cheaper to prevent a breakdown than to repair one.
When to Call a Professional
Even with great maintenance, refrigerators can develop issues. Watch out for these warning signs:
- Unusual noises — clicking, buzzing, or rattling sounds
- Water pooling inside or underneath the fridge
- Food spoiling faster than normal
- Frost buildup in the freezer
- Higher electricity bills with no clear reason
If you notice any of these, don’t wait. Catching a problem early is almost always cheaper than a full repair or replacement.
Final Thoughts
A well-maintained refrigerator can last 15–20 years. Neglected, it might give out in half that time. These five tips take minimal effort but deliver major returns — lower energy bills, fewer breakdowns, and peace of mind knowing your food is safely stored.

FAQs
How long should a refrigerator last?
A well-maintained refrigerator can last between 15 to 20 years. Without proper care, it may fail in as little as 8 to 10 years.
How often should I clean my refrigerator coils?
Every 6 to 12 months for most households. If you have pets that shed, aim for every 3 to 6 months.
How do I know if my door gasket needs replacing?
Do the dollar bill test — close the door on a dollar bill and try to pull it out. If it slides out easily, your seal is weak and needs attention.
Why is my refrigerator running constantly?
This is usually caused by dirty condenser coils, a worn door gasket, or incorrect temperature settings. If the problem persists, call a professional.
Is it worth repairing a refrigerator or should I replace it?
If the repair cost is less than 50% of the price of a new unit and the fridge is under 10 years old, repair is usually the better choice.
