Regular Maintenance
Keeping your refrigerator clean and well-maintained plays a crucial role in temperature optimization. Regularly check seals, clean coils, and defrost as necessary to ensure optimal performance:
| Maintenance Task | Frequency |
|---|---|
| Check Door Seals | Monthly |
| Clean Coils | Every 6 months |
| Defrost Freezer | As needed |
Organize Food Efficiently
Organizing food items ensures nothing is blocking the vents, allowing cold air to circulate properly.
Special Considerations
Certain foods require extra care when it comes to refrigerator temperature.
Meat and Poultry
Raw meat and poultry should always be kept at or just below **40°F (4°C)** to prevent the growth of harmful bacteria. Use airtight containers to avoid cross-contamination, especially with juices.
Dairy Products
Dairy should also be stored at temperatures below **40°F (4°C)**. Pay special attention to milk, which can spoil quickly when exposed to higher temperatures.
