| Bottom Shelf | 32-36°F (0-2°C) |
| Crisper Drawers | 34-40°F (1-4°C) |
Keeping the middle shelves slightly cooler can help in prolonging the freshness of your perishables.
Understanding the Fridge Layout
The internal layout of your refrigerator can also influence temperature consistency.
Hot Spots in Refrigerators
Different areas of your fridge have varying temperatures. Generally, the upper shelves are warmer than the lower shelves and crisper drawers where cold air settles.
Upper Shelves:
- A bit warmer, ideal for drinks, leftovers, and ready-to-eat meals.
Middle Shelves:
- The most consistent temperature, perfect for dairy products and eggs.
Lower Shelves:
- Colder temperatures, ideal for storing meats and fish.
Crisper Drawers:
- Specifically designed for fruits and vegetables, they often have different humidity settings.
Understanding these variations can help you store your food effectively and maintain optimal freshness.
Common Refrigerator Problems and Solutions
Even with the right settings, various issues can arise that impact your refrigerator’s performance. Here are some common refrigerating troubles and how to troubleshoot them:
