How do I tell if a refrigerator is working

If you're wondering if your refrigerator is working properly, there are a few things you can check.

Check the temperature. The ideal temperature for a refrigerator is between 37 and 40 degrees Fahrenheit. You can use a refrigerator thermometer to check the temperature. If the temperature is too high or too low, your refrigerator may not be working properly.
Listen for noises. A properly working refrigerator should make a quiet humming sound. If you hear any loud noises, such as banging or grinding, it could be a sign that your refrigerator is not working properly.
Check for frost or ice buildup. Frost or ice buildup on the inside of your refrigerator can be a sign that it is not working properly. If you see any frost or ice buildup, you should defrost your refrigerator.
Check the door seal. The door seal is what keeps the cold air in and the warm air out. If the door seal is damaged, warm air can leak into your refrigerator, causing the temperature to rise. You can check the door seal by closing the door on a piece of paper. If the paper can be pulled out easily, the door seal may need to be replaced.
Call a qualified appliance repair technician. If you have checked all of the above and you are still not sure if your refrigerator is working properly, you should call a qualified appliance repair technician.
