When it comes to maintaining a refrigerator, there are several components that play a crucial role in ensuring it operates efficiently and effectively. One of the most critical components is the compressor, which is responsible for compressing the refrigerant that circulates through the system, allowing the refrigerator to cool the interior. A faulty compressor can lead to a range of problems, including reduced cooling performance, increased energy consumption, and even complete system failure. Therefore, it is essential to know how to check the compressor on a refrigerator to identify any potential issues early on and take corrective action before they escalate into more significant problems.
Regular maintenance and checks can help prevent compressor failure and ensure the longevity of the refrigerator. In this article, we will delve into the world of refrigerator compressors, discussing their function, types, and common issues. We will also provide a step-by-step guide on how to check the compressor on a refrigerator, including the tools and materials needed, safety precautions, and troubleshooting tips.
Understanding Refrigerator Compressors
A refrigerator compressor is a critical component that plays a vital role in the refrigeration cycle. Its primary function is to compress the refrigerant, which is a liquid that changes state from liquid to gas as it absorbs heat from the refrigerator’s interior. The compressed refrigerant is then pumped through the condenser coils, where it releases its heat to the surrounding air. The refrigerant then expands through the expansion valve, causing it to cool down, and eventually, it enters the evaporator coils, where it absorbs heat from the refrigerator’s interior and repeats the cycle.
There are several types of refrigerator compressors, including:
- Reciprocating compressors: These are the most common type of compressor used in refrigerators. They use a piston and cylinder arrangement to compress the refrigerant.
- Scroll compressors: These compressors use a spiral-shaped scroll to compress the refrigerant. They are commonly used in high-efficiency refrigerators.
- Rotary compressors: These compressors use a rotating vane to compress the refrigerant. They are commonly used in small refrigerators and freezers.
Common Issues with Refrigerator Compressors
Refrigerator compressors are prone to several common issues, including:
- Overheating: This can cause the compressor to fail prematurely. Signs of overheating include a hot compressor, excessive vibration, and a burning smell.
- Low refrigerant levels: This can cause the compressor to work harder, leading to increased energy consumption and reduced cooling performance.
- Worn-out seals and gaskets: These can cause refrigerant leaks, leading to reduced cooling performance and increased energy consumption.
- Compressor motor failure: This can cause the compressor to stop working altogether.

Tools and Materials Needed
- Refrigerant leak detector
- Compressor oil
- Compressor gasket sealant
- Socket wrench or ratchet and socket
- Compressor removal tool (if necessary)
Safety Precautions
- Turn off the power to the refrigerator at the circuit breaker or fuse box.
- Unplug the refrigerator from the power outlet.
- Wear protective gloves and safety glasses.
Step-by-Step Instructions
- Locate the compressor: The compressor is usually located at the back or bottom of the refrigerator.
- Remove the compressor cover: Use a socket wrench or ratchet and socket to remove the compressor cover.
- Check the compressor oil: Use a dipstick or oil level gauge to check the compressor oil level.
- Check for refrigerant leaks: Use a refrigerant leak detector to check for any leaks in the compressor or surrounding areas.
- Check the compressor gaskets and seals: Inspect the compressor gaskets and seals for any signs of wear or damage.
- Check the compressor motor: Use a multimeter to check the compressor motor for any signs of wear or damage.
Troubleshooting Tips
- If the compressor is not turning on, check the power supply and ensure that the circuit breaker or fuse has not tripped.
- If the compressor is making a strange noise, check the compressor gaskets and seals for any signs of wear or damage.
- If the compressor is not cooling properly, check the refrigerant levels and ensure that the compressor is properly sealed.
