What is the normal temperature for a refrigerator? 

• The average temperature inside the refrigerator must be between 35°F and 38°F  (1.7°C to 3.3°C)

Keeping your food fresh and safe is a top priority in any household. But what temperature should a refrigerator be to ensure optimal food preservation? Understanding the ideal refrigerator temperature not only extends the shelf life of your groceries but also helps prevent foodborne illnesses. 

Ideal temperature for your refrigerator and acceptable range 

The best refrigerator temperature is typically between 35°F and 38°F (1.7°C to 3.3°C). This range slows down bacterial growth without freezing your food. According to the U.S. Food and Drug Administration (FDA), setting your fridge at 40°F (4°C) or below is essential for food safety. 

To ensure accuracy, it’s advisable to use a refrigerator thermometer. While most fridges come with built-in settings, they might not always be precise. Placing a standalone thermometer on a shelf can help you monitor the refrigerator temperature more accurately. 

The temperature in the refrigerator that is outside the norm 

• Above 40°F (4°C) means that the temperature in your fridge is too high
• Below 35°F (1.7°C) means that the temperature in your fridge is too low

If your refrigerator temperature falls outside the recommended range, your food could spoil faster or even freeze. Temperatures above 40°F (4°C) can promote the growth of harmful bacteria like Salmonella and E. coli. So, is 45 degrees a safe temperature for a refrigerator? No, it’s above the safe threshold. 

Why is the temperature in the fridge outside the norm?

Several factors can cause your fridge’s temperature to deviate: 

• Dusty coils: dust accumulation on the coils can reduce cooling efficiency, leading to temperature fluctuations.
• Overloading: too much food can obstruct air circulation. 
• Faulty components: malfunctions like a broken compressor can affect temperature. 
• Location: placing the refrigerator near heat sources can impact performance. 
• Age of the refrigerator: older units may struggle to maintain the proper refrigerator temperature due to wear and tear. 

The temperature in refrigerator is too high – how to fix 

If you notice that your fridge is warmer than it should be, here are some steps to take: 

• Check the refrigerator temperature setting: ensure that the thermostat is set within the ideal range. 
• Inspect the door seals: worn-out seals can let warm air in. Clean or replace them if necessary. 
• Clean the condenser coils: dust and debris on the coils can reduce cooling efficiency. 
• Avoid overloading: ensure there’s enough space for air to circulate around items. 
• Check for blocked vents: make sure nothing is obstructing the internal vents. 

Many modern refrigerators, such as models from Samsung and Whirlpool, come with user-friendly temperature controls that allow you to easily adjust the fridge and freezer settings. Most models have digital panels where you can set the exact temperature for both compartments. These controls often let you choose the specific degree to help maintain the optimal refrigerator temperature. For example, you can set the fridge to around 37°F (3°C) and the freezer to 0°F (-18°C).

Ways to fix too low temperature in refrigerator 

A fridge that’s too cold can freeze your food, affecting its texture and taste. It can also lead to higher energy bills. To fix this: 

• Adjust the thermostat: the refrigerator temperature control might be set too low. Adjust it incrementally and monitor the temperature over 24 hours. 
• Organize your fridge: proper airflow is crucial. Don’t block vents with food items. 
• Check the temperature sensor: a faulty sensor can send incorrect readings to the thermostat. 
• Inspect the damper: this component controls the amount of cold air entering the fridge from the freezer. 
• Defrost the freezer: ice buildup can impact temperature regulation. 

Regardless of whether your refrigerator is from LG, Kenmore, GE or another brand, checking the manual is the best way to ensure you’re setting the right temperature for your model. 

How to fix the temp in your refrigerator DIY?

Feeling handy? Here are some DIY steps: 

1. Use a refrigerator thermometer: place it in the center of the fridge to get an accurate reading. 
2. Adjust the temperature setting: use the control panel to set the desired temperature. 
3. Clean the condenser coils: located at the back or bottom, clean them with a brush or vacuum. 
4. Inspect door seals: close a dollar bill in the door, if it slips out easily, the seals may need replacing. 

5. Check the vents: ensure that air vents inside the fridge aren’t blocked by food items. 
6. Defrost the freezer: ice buildup can impact temperature. 
7. Replace faulty components: parts like the thermostat or fans might need replacing. 
8. Consider refrigerant levels: in older refrigerators, low refrigerant levels can cause cooling issues. Recharging refrigerant is a complex task that should only be performed by a certified technician. 

Always unplug your fridge before attempting any repairs. If you’re unsure, it’s best to consult a professional. 

The benefits of calling a technician to fix fridge temp 

While DIY fixes can be helpful, calling a technician offers several advantages: 

• Expert diagnosis: technicians can identify underlying issues that might not be apparent. 
• Safety first: avoid the risk of electrical shocks or causing further damage. 
• Proper refrigerant handling: professionals are trained to safely handle refrigerants. 
• Warranty protection: professional repairs often come with service guarantees. 
• Extending appliance lifespan: regular maintenance can prolong the life of your refrigerator. 

As refrigerators get older, components like compressors and fans can wear out, leading to temperature inconsistencies. Low refrigerant levels are common in aging units and require professional attention.
