1. Ensure Proper Temperature Settings
The ideal temperature range for your refrigerator is 35°F to 38°F for the fresh food compartment and 0°F to 5°F for the freezer. Even a few degrees cooler than necessary wastes substantial energy over time.
Follow these tips for proper temperature settings:
- Use an inexpensive fridge/freezer thermometer to monitor the actual interior temperatures. Don’t rely solely on the dial or digital panel.
- Adjust the settings incrementally, allow 24 hours for the temperature to stabilize before making additional changes.
- Make sure the air can properly circulate by not overloading the fridge or blocking vents.
- Open the doors sparingly to limit cold air escaping.
Proper temperatures keep food fresher longer and reduce strain on the compressor. Taking the time to configure the optimal temperature settings will maximize efficiency and performance.
2. Install New Fridge Door Seals
Worn out door seals allow cold air to leak from your refrigerator, forcing the compressor to work harder to maintain the correct interior temperatures.
Consider installing new door seals if:
- The seals are cracked or feel brittle. Gently bend the seal and inspect for any breaks, tears or dry areas.
- The seal does not make full contact with the fridge body. Look for gaps where the seal meets the surface, especially near the corners. Slip a piece of paper between the seal and fridge and tug gently – it shouldn’t pull out easily.
- You notice frost build up around the seal edges. This indicates cold air is escaping from gaps in the seal.
High quality replacement seals can be easily installed in under an hour, even for those with limited DIY experience. This inexpensive upgrade can have a big impact on energy efficiency and fridge performance.
3. Organize Your Refrigerator Strategically
Strategically organize your refrigerator and freezer compartments to maximize efficiency. Apply these tips:
- Group similar items in bins, on shelves or in crisper drawers to reduce time spent searching with the doors open.
- Position frequently used items on middle shelves where they are easily accessible.
- Avoid overcrowding shelves to enable unobstructed air circulation.
- Let hot food cool before placing in the refrigerator to reduce load on the compressor.
- Keep the refrigerator 2⁄3 full. Over or under-filling reduces efficiency.
- Regularly check for expired items as they can leak and damage other food.
Taking the time to thoughtfully organize your refrigerator ensures items are easy to locate, maintains proper air flow and reduces door openings, boosting efficiency.
4. Use Temperature Zones Strategically
Modern refrigerators have different temperature zones that can be utilized strategically:
- The upper area and door shelves are the warmest sections, best used for drinks, condiments, butter, cheeses and leftovers.
- The center shelves maintain an average temperature ideal for dairy, eggs, meats, fish and prepared meals.
- Crisper drawers have higher humidity levels, perfect for storing fruits, vegetables and leafy greens.
- Chiller drawers provide coldest temperatures for deli items, meats and leftovers needing maximum freshness.
Storing items in appropriate zones based on ideal temperatures prevents over-chilling and deterioration in quality. It also allows you to fully leverage the varied capabilities of your refrigerator. Check your owner’s manual for specific guidance on optimal temperature zones.
5. Allow Proper Airflow and Circulation
For maximum efficiency, refrigerators require proper airflow and circulation to maintain precise interior temperatures:
- Leave 2-3 inches clearance behind the fridge and above for air exhaust.
- Cool hot food before placing inside to avoid temperature spikes.
- Organize contents to prevent blocking internal vents.
- Avoid overcrowding shelves and drawers which reduces air movement.
- Adjust temperature controls seasonally as needed.
Regularly inspecting your refrigerator’s airflow pathways and making adjustments helps maintain optimal temperatures with minimal energy usage.
6. Keep Condenser Coils Clean
Dust-filled condenser coils force your refrigerator’s compressor to work harder, using excess energy:
- Check coils annually by unplugging the fridge and looking underneath or behind the lower back panel.
- Clean dust and debris from coils with a vacuum hose brush attachment or coil cleaning brush.
- For stubborn dirt, use a spray condenser coil cleaner available at home improvement stores.
Keeping condenser coils free of dust buildup improves ventilation, allowing your refrigerator to operate more efficiently.
7. Upgrade to an Energy Efficient Model
While improving your current refrigerator’s efficiency is beneficial, replacing an older unit with a new ENERGY STAR® certified appliance can dramatically increase energy savings.
Features to look for include:
- Variable speed compressor that operates based on cooling demand.
- Improved door seals that compress against the cabinet.
- LED lighting to reduce heat generation.
- Automatic fan shut-off when doors are open.
- Quick ice settings that freeze only the amount desired.
New refrigerators can be up to 50% more efficient than those manufactured over 15 years ago. Take advantage of energy rebates, tax credits and utility incentives to maximize your return on investment when upgrading.
8. Adjust Settings Before Vacations
Make refrigerator adjustments prior to vacations or extended away periods:
- Raise the temperature settings from 38°F to 45°F in the refrigerator and 0°F to 15°F in the freezer.
- Empty and unplug the icemaker to prevent leaks.
- Remove perishable items that may spoil. Leave other items.
- Shut off automatic defrosters to conserve energy.
- Leave fridge and freezer doors slightly ajar to air out.
- Upon return, allow time to cool down before restocking.
Properly configuring your refrigerator before vacations prevents energy waste, avoids spoilage and saves you money.
