Extend the Life of Your Refrigerator with Proper Maintenance
Why Regular Refrigerator Maintenance Matters
Your refrigerator runs 24/7 to keep your food cold, and without consistent maintenance, dust, debris, and worn components can cause temperature problems, higher energy bills, leaks, strange noises, or even complete breakdowns. Simple routine care helps keep your fridge efficient, prevents major repairs, and extends the life of the compressor, which is the most expensive part to replace.
This guide explains how to properly maintain your refrigerator at home, and when it’s best to call a professional for help.
This maintenance guide is suitable for all major refrigerator types:
- French-door refrigerators
- Side-by-side refrigerators
- Top-freezer and bottom-freezer refrigerators
- Counter-depth and built-in models
- Single-door and compact refrigerators
- Units with or without ice makers and water dispensers
Whether you own a basic model or a high-end system, following these maintenance steps will help your refrigerator run smoothly and reliably year-round.
How to Maintain Your Refrigerator
Follow these simple steps to keep your refrigerator cooling properly and running efficiently year-round.
1. Keep the Cooling System Clean
Clean the Condenser Coils (Every 6 Months)
Dust and debris on the coils cause your refrigerator to work harder, leading to higher energy bills and overheating. Use a vacuum and coil brush to gently remove buildup around the coils behind or beneath the refrigerator.
If the coils are extremely dirty or hard to reach, schedule a professional cleaning.
Listen to the Fans
The evaporator and condenser fans should run smoothly and quietly. If you hear rattling, clicking, or unusually loud humming, airflow may be restricted.
Unusual noises may signal early component failure — have a technician inspect it.
2. Protect the Door Seals
Clean the Rubber Gaskets
Wipe the door seals regularly with warm soapy water to remove crumbs, sticky spills, and mold. Clean seals help keep cold air inside.
Test the Seal Strength
Close a thin piece of paper in the door and try pulling it out. If it slides out easily, the gasket may be worn.
Damaged or stretched door seals should be replaced professionally.
3. Keep Temperatures Accurate
Set the Right Temperatures
- Refrigerator: 37°F
- Freezer: 0°F
Proper temperature helps food stay fresh longer and reduces compressor strain.
Watch for Temperature Swings
If food spoils fast or the refrigerator feels warmer than usual, the thermostat or control board may need attention.
Sudden temperature changes should be checked by a professional.
4. Prevent Leaks and Drain Issues
Clear the Defrost Drain
A clogged drain line can cause water puddles inside the fridge or under the drawers. Flush the drain hole with warm water to remove simple blockages.
Persistent leaks often indicate a defrost system issue — schedule service.
5. Maintain Ice and Water Flow
Replace Water Filters Every 6 Months
Old filters can cause poor-tasting ice, slow water flow, and mineral buildup.
Inspect Water Lines
Check behind the fridge for kinks or small leaks around the water line connection.
If ice production slows down or stops completely, let a technician diagnose it.
6. Clean the Interior Regularly
Wipe Shelves and Drawers Weekly
Clean surfaces reduce odors and maintain food safety.
Use a Deodorizer
Place baking soda or a fridge deodorizer to help control odors and moisture.
7. Check Overall Performance
Pay Attention to Sounds
Loud buzzing, knocking, or clicking are signs that internal components may be wearing out.
Make Sure the Refrigerator Is Level
A level refrigerator allows doors to close properly and prevents compressor strain.
If the doors don’t seal smoothly or you see frost forming around the freezer door, professional adjustment is recommended.
How often to service your refrigerator
Every 6–12 months
Regular refrigerator maintenance prevents temperature problems, stops leaks before they start, keeps energy usage low, and extends the life of your cooling system. A yearly check-up also helps identify early signs of component wear before they become expensive repairs.
Pro Tips to Keep Your Refrigerator Running Smoothly
Regular, simple care can make a big difference in how efficiently your refrigerator runs. These easy habits help you maintain proper cooling, reduce energy use, and prevent early wear on important components.
- Keep 2–3 inches of space behind and around the fridge for better airflow.
- Replace your water filter every 6 months to maintain clean water and clear ice.
- Avoid overpacking shelves — proper air circulation keeps temperatures stable.
- Wipe spills quickly to prevent odors and bacteria from spreading.
- Check door seals monthly to make sure they close tightly and don’t let cold air escape.
