Typically placed either inside the refrigerator or on the exterior panel. Identify the temperature control settings.
Step 2: Set the New Temperature
Adjust the dial (or digital interface) to the desired setting, ideally between 35°F to 38°F.
Step 3: Wait for the Temperature to Stabilize
After adjusting, give the refrigerator 24-48 hours to stabilize the new temperature. Use a thermometer to check the accuracy.
Step 4: Final Checks
Regularly monitor the temperature for any fluctuations. If you notice any changes, consider seeking professional help to examine your refrigerator’s functionality.
Signs Your Refrigerator Temperature Is Not Correct
Keeping your refrigerator at the right temperature is essential, but sometimes it’s not obvious when it’s not working as it should. Here are some signs to watch out for:
Food Spoilage
If you find that food spoils quickly or certain items develop an unusual odor, it may signal that the temperature is not set correctly.
