Common Reasons Why the Compressor Is Always On
A continuously running refrigerator compressor can be a cause for concern. The reasons behind this can be many, and understanding each can guide you in resolving the issue. Let’s explore the common reasons one by one:
High room temperature
Your refrigerator works overtime in a high-temperature environment. It is designed to maintain a cool internal environment, and when the room temperature soars, it struggles, causing the compressor to remain active longer.
Maintaining room temperature below 90 degrees Fahrenheit (32 degrees Celsius) can be a good practice.
Door seals
Door seals or gaskets play a crucial role in keeping the cool air inside and the warm air out. Over time, they can wear out, become loose, crack, or even tear, compromising the insulation. This forces the compressor to work harder to maintain the set temperature.
Regular inspection for any visible signs of wear and tear and ensuring they are clean and free from food residues can help in maintaining their efficiency.
Thermostat issues
The thermostat is the refrigerator’s regulator, instructing the compressor when to start and stop based on the temperature settings. A malfunctioning thermostat can send incorrect signals, causing the compressor to run non-stop.
It is advisable to check if the thermostat is functioning correctly by setting different temperatures and observing if the compressor responds accordingly.
Dirty coils
The condenser coils are responsible for dissipating the heat pulled out from the refrigerator. Over time, they accumulate dirt, dust, and grime, which impairs their ability to dissipate heat efficiently, putting extra pressure on the compressor.
Regular cleaning, at least once or twice a year, can prevent this issue.

Steps to Troubleshoot ‘Refrigerator Compressor Always On’
If your refrigerator compressor is always on, it is essential to diagnose and rectify the issue promptly to prevent higher energy bills and wear on your appliance. Below, we provide a step-by-step guide to help you troubleshoot the problem:
Check the thermostat
Begin by examining the thermostat. It is usually located inside the refrigerator or freezer compartment. Firstly, confirm that it is set to the manufacturer’s recommended settings.
Then, gradually adjust the temperature settings: decrease it and observe if the refrigerator cools down accordingly, then increase it and check if it warms up slightly. This will help you understand if the thermostat is working correctly.
Inspect the door seals
Next, check the refrigerator and freezer door seals. Close the door with a dollar bill or a piece of paper halfway in. If the bill or paper pulls out easily without resistance, it is a sign of weak seals that need replacement.
Ensure to clean the seals regularly with a mild detergent to prevent the build-up of residues that can affect their performance.
Clean the coils
Locate the refrigerator’s coils; they could be at the back or bottom of the unit. Ensure to unplug the refrigerator first for safety.
Use a coil cleaning brush (like this Vanitek Dryer Vent Cleaner Lint Brush from Amazon) or a vacuum cleaner to remove dust and dirt accumulated over time. Cleaning the coils improves the efficiency of the refrigerator and reduces the strain on the compressor.
Monitor room temperature
Keep a thermometer in the room to regularly monitor the temperature. If it’s too high, it can cause the compressor to work continuously.
Try to maintain a moderate room temperature to prevent the refrigerator from overworking.
Consult a professional
If you have tried all the above steps and the compressor is still running continuously, it is best to consult a professional technician. They would be equipped to identify and fix any underlying issues, be it electrical problems or refrigerant leakage, ensuring your refrigerator functions correctly and efficiently.
