Is your fridge making strange noises, not cooling properly, or smelling funky? Poor maintenance can lead to spoiled food, higher energy bills, and costly repairs. The right refrigerator maintenance can extend its lifespan, improve efficiency, and keep your food fresh. In this guide, we’ll cover essential tips, from cleaning coils to optimizing storage.

Key Takeaways

• Clean condenser coils every 6 months to prevent overheating
• Maintain ideal temps: 37°F (3°C) for fridge, 0°F (-18°C) for freezer
• Check door seals monthly for air leaks
• Defrost manual-freeze models when ice exceeds ¼ inch

1. Clean Condenser Coils Every 6 Months

Dirty coils force your fridge to work 30% harder, increasing energy bills. Locate coils (typically at the back or bottom front) and:

• Unplug the unit first for safety
• Use a coil brush or vacuum with crevice tool
• Remove pet hair and dust bunnies
• Wipe with a damp cloth if greasy

Pro tip: Place a high-suction vacuum behind your fridge during routine cleanings.

2. Maintain Proper Temperature Settings

Incorrect temps cause food spoilage and energy waste. Use an appliance thermometer to verify:

Adjust the thermostat gradually—large swings strain the compressor.

3. Inspect and Clean Door Seals Monthly

Faulty gaskets account for 7% of fridge energy loss. Test seals by closing a dollar bill in the door—if it slips out easily, replace the gasket. Clean monthly with:

• Mild soap and warm water
• Soft toothbrush for crevices
• Rubber protectant to prevent cracking

4. Organize Contents Strategically

Overloading blocks airflow, while underfilling wastes energy. Follow these storage rules:

• Leave 1-inch space between items and walls
• Store liquids in back where it’s coldest
• Use clear bins for visibility (like these storage solutions)
• Group similar items together

5. Defrost Freezer When Ice Builds Up

¼ inch of ice reduces efficiency by 10%. For manual-defrost models:

• Unplug and empty contents into coolers
• Place towels to catch melting ice
• Use plastic scraper—never metal
• Wipe dry before restarting

6. Deep Clean Interior Quarterly

Bacteria like Listeria can thrive in fridge spills. Use this cleaning routine:

1. Remove all food and shelves
2. Mix 2 tbsp baking soda with 1 quart warm water
3. Scrub surfaces with soft cloth
4. Dry thoroughly before reloading
