🧊 Refrigerator Maintenance Tips to Extend Its Lifespan (2025 Guide)
Your refrigerator runs 24/7 to keep your food fresh, but how often do you maintain it? With just a little care, you can extend your fridge’s life by 5–10 years and prevent costly repairs.
In this guide, we’ll walk you through 10 expert-recommended fridge maintenance tips to help you save energy, reduce food waste, and avoid breakdowns—whether you own a French door, top freezer, side-by-side, or compact model.
1. Keep It Clean—Inside and Out
🧽 Clean the Interior Monthly
- Wipe down shelves and drawers with warm water and mild soap
- Use a baking soda solution (1 tbsp per quart) to neutralize odors
- Deep-clean every 3–6 months by unplugging and cleaning crevices and trays
Why it matters: A study by NSF found that fridge veggie compartments often harbor Salmonella and E. coli.
🧹 Clean the Exterior & Coils
- Vacuum condenser coils every 6 months
- Use a soft cloth to wipe down vents and control panels
- Clean behind/underneath the fridge (dust = heat = more power used)
Dirty coils can reduce efficiency by up to 30%, according to global energy experts.
2. Set the Right Temperature
- Refrigerator: 37°F (3°C)
- Freezer: 0°F (-18°C)
Use a standalone thermometer to double-check. If it’s too cold, energy is wasted. If it’s too warm, food spoils faster.
3. Check the Door Seals
A broken door gasket causes cold air leaks. Test it with a dollar bill:
- Close the door with the bill halfway in
- If you can easily pull it out, the seal is worn
Fix it:
- Clean the gasket with warm, soapy water
- Apply petroleum jelly to keep it flexible
- Replace if cracked or warped
4. Defrost When Needed
Manual Defrost Models
Defrost every 3–6 months or when frost exceeds ¼ inch.
Frost-Free Models
Still clean yearly to avoid hidden ice buildup. Remove drawers and check rear vents for frost.
5. Organize Food for Airflow
- Leave gaps between items
- Don’t block vents at the back
- Keep liquids sealed to reduce humidity
A Consumer Reports study found that cluttered fridges can use 10–15% more energy.
6. Replace the Water Filter
If your fridge dispenses water or ice:
- Replace the filter every 6 months
- Clogged filters reduce flow and may allow contaminants like lead or chlorine to pass through (EPA)
7. Don’t Ignore Noises or Leaks
- Buzzing or grinding: Fan or compressor issue
- Water pooling: Check for a blocked defrost drain
- Rattling or vibration: May need leveling
Fixing small issues early can save you $200–$500 in repairs later.
8. Keep Your Fridge Level
- Use a bubble level to check
- Adjust front leveling legs if needed
An uneven fridge can lead to compressor strain, poor drainage, and door seal issues.
9. During Power Outages
- Don’t open the doors
- A full freezer stays cold for up to 48 hours
- Use ice packs or frozen water bottles in the fridge
Tip: Keep a thermometer inside to track the temperature after an outage.
10. Know When to Call a Professional
Call for help if:
- The fridge keeps cycling on and off
- The freezer is cold, but the fridge is warm
- There’s excessive frost in a frost-free unit
🧠 Bonus Tips
- Don’t store hot food directly—let it cool before placing it inside
- Keep your fridge 2–3 inches away from the wall
- Label leftovers with dates to reduce waste and limit odors
