How To Quickly Determine The Refrigerator Compressor Low Side

Compressor Location:

Identifying the compressor itself is the first step. The compressor is a sealed, black component that looks like a cylindrical tank with multiple pipes linked to it. Typically, it is situated towards the rear of the refrigerator.

Locating the Suction Line:

The compressor’s low side attaches to the suction line, a larger-diameter, insulated conduit compared to the high side. The suction line is responsible for drawing the refrigerant gas into the compressor.

Examining the Pressure Ports:

Pressure ports on the majority of compressors are labeled “H” for the high side and “L” for the low side. Find the compressor’s ports here. The suction line connection is located at the low side port.

See the handbook provided by the manufacturer:

Consult the manufacturer’s instructions for your refrigerator if you’re experiencing problems determining the low side. The manual often includes detailed schematics and information about the refrigerator compressor’s parts.

Why It’s Important To Locate The Refrigerator Compressor’s Low Side

Maintenance and Repairs:

For maintenance and troubleshooting, it is essential to understand the low side. To perform operations like refilling refrigerant or finding leaks, technicians frequently need to access the lower section of your refrigerator during maintenance.

Optimizing Performance:

Accurately identifying the low side enables efficient refrigeration cycle monitoring. With this knowledge, you can ensure that your refrigerator runs efficiently and extends its lifespan by optimizing its performance.

Efficiency of Energy:

Maintaining a low side properly helps with energy efficiency. Your refrigerator will use less energy and your power costs will go down if the refrigerant cycle is kept in balance.


Any homeowner should be able to identify the compressor on the low side of their refrigerator. It helps with regular maintenance and gives, after all, you the ability to troubleshoot and improve the functioning of your refrigerator. You’ll be in a better position to make sure your refrigerator runs efficiently, keeping your food fresh and your energy costs under control, by following the instructions provided in this guide. Thus, give your compressor some time to get to know it and unleash the potential of a reliable and effective refrigerator.
