How to Troubleshoot and Repair Compressor Short Cycling – An Essential Guide

My elderly neighbor called me the other night, in a panic. Her refrigerator had suddenly stopped working, and she didn’t know what to do. As I walked into her kitchen, I realized the issue was compressor short cycling. The compressor was starting and stopping repeatedly, never reaching its operating temperature.

What is Compressor Short Cycling?

Compressor short cycling is a condition where the compressor in a refrigeration system starts and stops more frequently than normal. This can be caused by a variety of factors, but the most common are refrigerant leaks, faulty components, or dirty coils.

Troubleshooting Compressor Short Cycling

To troubleshoot compressor short cycling, start by checking the following:

1. Refrigerant Level: Use a refrigerant pressure gauge to check the refrigerant level. If the level is low, you may have a leak.

2. Faulty Overload Protector: The overload protector is a safety device that protects the compressor from overheating. If the overload protector is faulty, it may be tripping prematurely, causing the compressor to shut off.

3. Capacitor: The capacitor helps the compressor start. If the capacitor is faulty, it may not be able to provide enough power to start the compressor.

4. Dirty Coils: Dirty coils can restrict airflow, which can cause the compressor to overheat and shut off.

5. Faulty Thermostat: The thermostat controls the temperature of the refrigerator. If the thermostat is faulty, it may be causing the compressor to cycle too frequently.

Fixing Compressor Short Cycling

Once you have identified the cause of the compressor short cycling, you can begin repairs.

1. Refrigerant Leaks: If you have a refrigerant leak, you will need to find and repair the leak. This may require the help of a professional.

2. Faulty Overload Protector: If the overload protector is faulty, you will need to replace it.

3. Capacitor: If the capacitor is faulty, you will need to replace it.

4. Dirty Coils: Clean the coils with a vacuum cleaner or a coil brush.

5. Faulty Thermostat: If the thermostat is faulty, you will need to replace it.
