What Happens When a Refrigerator Goes Bad?

When a refrigerator goes bad, it can cause food spoilage, higher energy bills, unpleasant odors, and potential health risks. To avoid these problems, it is important to know the signs of a failing refrigerator and how to fix or replace it. In this article, we will explain what causes a refrigerator to go bad, how to diagnose and troubleshoot common issues, and when to call a professional for help.

Causes of Refrigerator Failure

A refrigerator is a complex appliance that relies on several components to function properly. Some of the main parts that can cause a refrigerator to go bad are:

  • Compressor: The compressor is the heart of the refrigerator, as it pumps refrigerant through the coils to cool the interior. If the compressor fails, the refrigerator will not cool at all or will run constantly, making loud noises and consuming more electricity.
  • Evaporator fan: The evaporator fan circulates cold air from the freezer to the refrigerator. If the fan stops working, the freezer may still be cold, but the refrigerator will be warm and humid, leading to food spoilage and mold growth.
  • Condenser fan: The condenser fan cools the condenser coils, which release heat from the refrigerant to the outside. If the fan is blocked or broken, the coils will overheat and the refrigerator will not cool efficiently, causing the compressor to work harder and wear out faster.
  • Thermostat: The thermostat regulates the temperature inside the refrigerator and freezer. If the thermostat is faulty, the refrigerator may be too cold or too warm, freezing or spoiling the food. A faulty thermostat can also cause the refrigerator to run more often than necessary, wasting energy and money.
  • Door seal: The door seal, also known as the gasket, creates an airtight seal between the door and the refrigerator. If the seal is torn, cracked, or loose, cold air will leak out and warm air will enter, making the refrigerator work harder to maintain the temperature and increasing the risk of condensation and frost buildup.

How to Diagnose and Troubleshoot Common Refrigerator Problems

If you notice any of the following symptoms, your refrigerator may be going bad and need some attention:

  • The refrigerator is not cooling or is too warm: Check the thermostat setting and make sure it is not set too high or too low. Adjust the temperature if needed and wait for a few hours to see if the problem is resolved. If not, check the back of the refrigerator and make sure the condenser coils are clean and free of dust and debris. Use a vacuum cleaner or a brush to remove any dirt that may be blocking the airflow and preventing the coils from cooling. If the coils are clean, check the condenser fan and make sure it is spinning freely and not obstructed by anything. If the fan is not working, you may need to replace it or call a technician. If the fan is working, check the evaporator fan and make sure it is blowing cold air from the freezer to the refrigerator. If the fan is not working, you may need to defrost the freezer or replace the fan. If the fan is working, check the compressor and listen for any unusual noises or vibrations. If the compressor is not running or is making loud noises, you may need to replace it or call a technician.
  • The refrigerator is running constantly or cycling on and off frequently: Check the thermostat setting and make sure it is not set too low or too high. Adjust the temperature if needed and wait for a few hours to see if the problem is resolved. If not, check the door seal and make sure it is not damaged or dirty. Clean the seal with a damp cloth and soap and water, and replace it if it is torn or cracked. If the seal is intact, check the door hinges and make sure they are not loose or misaligned. Tighten the screws or adjust the hinges if needed. If the door is closing properly, check the ambient temperature and make sure it is not too hot or too cold. The ideal temperature range for a refrigerator is between 50°F and 95°F. If the temperature is outside this range, the refrigerator may have trouble maintaining the optimal temperature and may run more often or cycle on and off frequently. If the temperature is within this range, check the refrigerator’s location and make sure it is not exposed to direct sunlight or heat sources, such as ovens, stoves, or radiators. Move the refrigerator away from these sources if possible, or use curtains, blinds, or shades to block the sunlight. If the refrigerator’s location is not an issue, check the contents of the refrigerator and make sure they are not blocking the vents or the door. Rearrange the items if needed and avoid overloading or underloading the refrigerator, as this can affect the airflow and the temperature. If the contents are not an issue, check the power supply and make sure the refrigerator is plugged into a dedicated outlet and not an extension cord or a power strip. These devices can cause voltage fluctuations and damage the refrigerator’s components. If the power supply is not an issue, you may need to call a technician to inspect the refrigerator and diagnose the problem.
  • The refrigerator is making loud or unusual noises: Check the source of the noise and identify which part of the refrigerator is causing it. Some common noises and their causes are:
    • Buzzing or humming: This is a normal sound that indicates the refrigerator is running and the compressor is working. However, if the noise is too loud or persistent, it may indicate a problem with the compressor or the condenser fan. Check the compressor and the fan and make sure they are not loose, damaged, or obstructed by anything. If they are, you may need to tighten, repair, or replace them or call a technician.
    • Clicking or ticking: This is a normal sound that indicates the refrigerator is cycling on and off or the defrost timer is working. However, if the noise is too frequent or irregular, it may indicate a problem with the thermostat, the compressor, or the relay. Check the thermostat and make sure it is not set too low or too high. Adjust the temperature if needed and wait for a few hours to see if the problem is resolved. If not, check the compressor and the relay and make sure they are not worn out or faulty. If they are, you may need to replace them or call a technician.
    • Squeaking or squealing: This is an abnormal sound that indicates a problem with the evaporator fan or the fan motor. Check the fan and make sure it is not loose, damaged, or obstructed by anything. If it is, you may need to tighten, repair, or replace it or call a technician.
    • Gurgling or bubbling: This is a normal sound that indicates the refrigerant is flowing through the coils. However, if the noise is too loud or constant, it may indicate a problem with the refrigerant level or the coils. Check the coils and make sure they are not leaking, corroded, or clogged. If they are, you may need to repair or replace them or call a technician. Check the refrigerant level and make sure it is not too low or too high. If it is, you may need to refill or drain it or call a technician.

When to Call a Professional for Refrigerator Repair or Replacement

Some refrigerator problems are easy to fix by yourself, but others require the expertise and tools of a professional. If you are not confident or comfortable with repairing your refrigerator, or if the problem is beyond your skills or knowledge, it is best to call a professional for help. Some signs that you need a professional are:

  • The refrigerator is not cooling at all or is too warm, and you have checked and ruled out all the possible causes mentioned above.
  • The refrigerator is leaking water or refrigerant, and you cannot locate or fix the source of the leak.
  • The refrigerator is making loud or unusual noises, and you cannot identify or fix the cause of the noise.
  • The refrigerator is tripping the circuit breaker or blowing the fuse, and you cannot find or fix the electrical problem.
  • The refrigerator is more than 10 years old, and it is showing signs of wear and tear, such as rust, cracks, dents, or scratches.
  • The refrigerator is costing you more money in energy bills, repairs, or food waste than a new one would.

A professional can diagnose the problem, provide an estimate, and perform the repair or replacement safely and efficiently. To find a reliable and qualified professional, you can ask for recommendations from friends, family, or neighbors, or search online for reviews, ratings, and credentials. You can also contact the manufacturer of your refrigerator and ask for their authorized service providers or warranty information.
