How to Reset a Refrigerator Compressor? Explained

To reset a refrigerator compressor, you need to unplug the fridge for 10 minutes, then plug it back in and turn it on. This will allow the compressor to cool down and reset itself. If this does not work, you may need to check the thermostat, the overload relay, or the compressor itself for any faults or damages. In this article, we will explain how to reset a refrigerator compressor, why it is important, and what to do if the problem persists.

What is a Refrigerator Compressor and Why Does It Need to Be Reset?

A refrigerator compressor is the heart of the cooling system. It is a pump that compresses the refrigerant gas and circulates it through the evaporator and condenser coils. The compressor is responsible for maintaining the desired temperature inside the fridge and freezer compartments.

Sometimes, the compressor may overheat, malfunction, or stop working due to various reasons, such as power surges, voltage fluctuations, dust accumulation, mechanical wear and tear, or faulty components. When this happens, the fridge may not cool properly, make loud noises, or stop running altogether. This can lead to food spoilage, increased energy consumption, and potential fire hazards.

To prevent these issues, it is important to reset the compressor periodically or whenever you notice any signs of trouble. Resetting the compressor can help to clear any errors, restore the normal function, and extend the lifespan of the fridge.

How to Reset a Refrigerator Compressor in 3 Easy Steps

Resetting a refrigerator compressor is a simple and quick process that anyone can do at home. Here are the steps to follow:

  1. Unplug the fridge from the power outlet. This will cut off the electricity supply to the compressor and allow it to cool down. Wait for at least 10 minutes before plugging it back in. Do not open the fridge doors during this time, as this will let the cold air escape and make the compressor work harder when you turn it back on.
  2. Plug the fridge back in and turn it on. You should hear the compressor start running and feel the air blowing from the vents. Check the temperature settings and adjust them if needed. You may also want to clean the condenser coils at the back or bottom of the fridge, as they can collect dust and dirt over time and affect the cooling efficiency.
  3. Monitor the fridge performance and listen for any unusual sounds. If the fridge is working normally, you have successfully reset the compressor. If the fridge is still not cooling, making loud noises, or showing error codes, you may need to troubleshoot the problem further or call a professional for help.

What to Do If Resetting the Compressor Does Not Work

If resetting the compressor does not solve the problem, there may be other issues with the fridge that need to be addressed. Some of the common causes of compressor failure are:

  • Faulty thermostat. The thermostat is the device that regulates the temperature inside the fridge. If it is broken or misaligned, it may not send the correct signals to the compressor and cause it to run too long or too short. To check the thermostat, you can use a multimeter to test its resistance or a thermometer to measure the actual temperature inside the fridge. If the readings are not consistent with the settings, you may need to replace the thermostat or adjust its position.
  • Bad overload relay. The overload relay is the part that protects the compressor from overheating or overloading. It is located near the compressor and has a small box with wires attached to it. If the overload relay is defective, it may not cut off the power to the compressor when it reaches a certain temperature or current level. This can damage the compressor and cause it to stop working. To check the overload relay, you can use a multimeter to test its continuity or resistance. If the readings are zero or infinite, you may need to replace the overload relay.
  • Damaged compressor. The compressor is the most expensive and complex part of the fridge. It consists of a motor, a piston, a valve, and a cylinder. If any of these components are worn out, cracked, or leaking, the compressor may not function properly or at all. To check the compressor, you can use a multimeter to test its resistance or a clamp meter to measure its current draw. If the readings are too high or too low, you may need to replace the compressor or have it repaired by a professional.

Conclusion

Resetting a refrigerator compressor is a simple way to fix some of the common problems that affect the fridge performance and efficiency. By unplugging the fridge for 10 minutes and plugging it back in, you can clear any errors, restore the normal function, and extend the lifespan of the compressor. However, if resetting the compressor does not work, you may need to check the thermostat, the overload relay, or the compressor itself for any faults or damages. If you are not confident or experienced in doing these tasks, you should contact a qualified technician for assistance.
