A refrigerator compressor is a vital component of a refrigeration system that plays a central role in cooling and maintaining the desired temperature inside the refrigerator. Its primary function is to circulate refrigerant gas through the cooling system, which facilitates the transfer of heat from the interior of the refrigerator to the external environment, thereby cooling the contents inside. Here's a breakdown of what a refrigerator compressor does and how it works:

  • Circulation of Refrigerant -The compressor takes low-pressure, low-temperature refrigerant gas from the evaporator coils (located inside the refrigerator) and compresses it into high-pressure, high-temperature gas.
  • Compression -The compressor compresses the refrigerant gas using mechanical force, which causes the gas molecules to come closer together, resulting in an increase in both pressure and temperature.
  • Heat Exchange -The high-temperature, high-pressure gas is then pushed through the condenser coils (located outside the refrigerator). As the gas flows through the condenser coils, it releases heat to the surrounding environment, causing the gas to condense and transform into a high-pressure liquid.
  • Expansion Valve -The high-pressure liquid refrigerant is then passed through an expansion valve or capillary tube, where it undergoes a rapid expansion. This expansion causes the refrigerant to become a low-pressure, low-temperature mixture of gas and liquid.
  • Evaporation -The now low-pressure refrigerant enters the evaporator coils inside the refrigerator's main compartment. As it evaporates, it absorbs heat from the interior of the fridge, effectively cooling down the contents.
  • Continuous Cycle - The cycle repeats continuously, with the compressor continuously drawing in low-pressure, low-temperature gas from the evaporator and compressing it into high-pressure, high-temperature gas. This cycle is what maintains the desired temperature inside the refrigerator, keeping the contents cool and fresh.

What Causes A Refrigerator Compressor To Stop Working?

A refrigerator compressor can stop working due to various factors, ranging from normal wear and tear to more complex technical issues. Here are some common reasons why a refrigerator compressor might stop working:

  • Electrical Issues -Compressors rely on electrical components to function properly. Electrical problems such as faulty wiring, blown fuses, tripped circuit breakers, or issues with the start relay can prevent the compressor from receiving the necessary power to run.
  • Overheating -Compressors generate heat as they operate, and they are designed with safeguards to prevent overheating. However, if the cooling system (such as the condenser coils) is clogged or dirty, the compressor can overheat, leading to a shutdown. Regular cleaning and maintenance of the cooling components can prevent this issue.
  • Start Relay Failure -The start relay is a component that helps the compressor start-up. If the start relay fails, the compressor might struggle to start or fail to start altogether. A faulty start relay can be replaced to restore compressor functionality.
  • Mechanical Failures -Internal mechanical components of the compressor, such as the motor or piston, can wear out over time. These failures might result in the compressor being unable to operate as intended.
  • Refrigerant Leaks -Refrigerant is essential for the compressor to function properly. If there's a refrigerant leak in the system, the compressor can struggle to maintain the necessary pressure, leading to a shutdown. Refrigerant leaks should be repaired by a professional technician.
  • Electrical Component Malfunction -Beyond the compressor itself, various electrical components like capacitors, relays, and overload protectors can fail, preventing the compressor from running.
  • Age and Wear -Like any mechanical component, a refrigerator compressor has a finite lifespan. Over time, the wear and tear can lead to decreased efficiency and eventual failure.
  • Voltage Fluctuations -Unstable voltage levels, such as power surges or brownouts, can impact the compressor's operation. Voltage fluctuations can stress the electrical components and lead to compressor failure.
  • Manufacturing Defects -In rare cases, manufacturing defects or poor-quality components can cause a compressor to fail prematurely.
  • Excessive Load -Overloading a refrigerator with warm items, especially in a short period, can cause the compressor to work harder than usual. This increased load can strain the compressor and potentially lead to failure.
  • Environmental Factors -Extreme temperature conditions, both hot and cold, can affect the compressor's performance. Extremely low temperatures, in particular, can cause the oil inside the compressor to become too thick, hindering its movement.

Identifying whether your refrigerator compressor is not working requires some observation and basic troubleshooting. Here are some common signs that can indicate a potential issue with your refrigerator compressor:

  • Lack of Cooling -If the refrigerator is not maintaining the desired temperature and your food is not as cold as it should be, the compressor might be struggling to cool properly.
  • Unusual Noises -While a certain amount of noise is normal, loud and unfamiliar noises, such as clicking, buzzing, or rattling, could indicate compressor issues. These noises might occur as the compressor tries to start but fails.
  • Constant Running or Cycling -If the compressor runs continuously without shutting off, or if it frequently turns on and off rapidly (short-cycling), this could suggest a problem with the compressor or other cooling system components.
  • Warm Exterior -If the exterior of the refrigerator feels warm to the touch, it might indicate that the compressor is working too hard or is overheating.
  • No Vibrations -Normally, the compressor produces a subtle vibration as it operates. If you don't feel any vibrations, it could indicate that the compressor is not running.
  • Noises from the Back -Place your ear close to the back of the refrigerator, near the compressor. If you hear a hum followed by a click or a buzz, it could be a sign that the compressor is trying to start but failing.
  • Condenser Fan Issues -The condenser fan, which helps cool the compressor and condenser coils, should run when the compressor is active. If the fan is not working, it can lead to compressor overheating and failure.
  • Water Leakage -If you notice water pooling around the refrigerator, it could be a sign of a compressor or cooling system issue. Sometimes, a failing compressor can cause excess condensation.
  • Freezer Defrosting -In a refrigerator with a separate freezer compartment, a failing compressor might lead to the freezer section not maintaining its proper temperature, resulting in defrosting or softening of frozen items.
  • Burnt Smell -A burnt or acrid smell coming from the refrigerator could indicate an electrical issue, possibly involving the compressor or other components.
  • Frequent Spoilage -If food is spoiling quickly or showing signs of spoilage despite proper storage, it might be due to the refrigerator not cooling effectively.

It's important to note that while these signs can point toward a compressor issue, they could also be indicative of other problems within the refrigerator's cooling system. If you notice any of these signs, it's advisable to:

  • Check Power -Ensure that the refrigerator is properly plugged in and the circuit breaker hasn't tripped.
  • Clean Condenser Coils -Dust and debris on the condenser coils can affect the compressor's performance. Clean them regularly.
  • Contact a Professional -If the issues persist or if you're uncertain about troubleshooting, it's best to consult a professional appliance repair technician. They can accurately diagnose the problem and recommend the appropriate solutions.
