Energy Efficiency and Maintenance Tips. While it's normal for a fridge to run continuously during the initial cooling phase, it shouldn't run excessively long once it reaches the desired temperature. To maintain energy efficiency, avoid overloading the fridge with warm items during the cooling process.
No, a refrigerator compressor should not run all the time. It operates on a cycle to maintain the desired temperature inside the fridge. Here's how it typically works: Cooling Cycle: The compressor runs to cool the interior of the refrigerator, cycling on when the temperature rises above a certain threshold.

For Refrigerators and Freezers to maintain the proper temperature, the compressor will run much of the time. Refrigerators and Freezers have compressors that are designed to run 80% to 90% of the time.
A new refrigerator should turn on and off itself periodically, as it is designed to maintain a consistent temperature inside the fridge. The frequency of these cycles can vary depending on the model and the surrounding environment, but typically a refrigerator will cycle on and off every 15-20 minutes.
If your fridge is cycling on and off incessantly, it is likely due to either a faulty thermostat, or the defrost timer or defrost thermostat. The defrost timer turns on and off the defrost heater which keeps your fridge at the right temperature.
Your variable speed compressor is designed to run 100% of the time except during the defrost cycle. At times it may even run faster, such as after a defrost cycle.
We recommend unplugging your refrigerator from power when you go out for a longer period. You will not need fresh food then. Make sure to dispose of any item that will go rotten without cooling. If your use of the refrigerator is minimal, then you can try turning off the fridge for a few hours at night.
However, the compressor and fan motors should only have to run occasionally throughout the day to maintain that cool temperature. If the compressor and fan motors are continuously running, it means the system is having trouble maintaining the temperature.
How often should a fridge start and stop? All fridges are 'on' most of the time. And by that I mean — it is typical for a refrigerator compressor to run anywhere between 4 and 8 hours before turning 'off'. Newer models run even more frequently — about 80% of the time.
If your refrigerator is running too long, it could be due to a malfunction of the defrost termination thermostat. This is the component in charge of turning off the defrost heater at the end of the defrost cycle, when the evaporator gets up to 35 to 47 degrees F. It can normally be found on the evaporator tubing.
Your refrigerator starts making strange noises. A gentle hum is normal as the fan motors inside your refrigerator do their job. Unusual sounds like grinding, scraping, knocking, or rattling are signs of bigger issues. You should also check your ice maker if you hear strange noises coming from your fridge.
Several potential causes could be making your fridge run continuously: dirty condenser coils, a faulty defrost heater, and problems with the defrost thermostat. To fix this issue, clean the condenser coils, replace the defrost heater if necessary, and check and replace the defrost thermostat if it's malfunctioning.
Refrigerators will make some noise whilst operating. If your fridge is making no noise, the interior is not cold enough but the light is on, it may be an indication that there is a fault. For example, your compressor may be damaged.
Condenser Fan Motor
The condenser fan blows cool air over the condenser coils to remove heat from the refrigerant, producing cool air for the refrigerator. If the fan malfunctions, the refrigerant may not cool sufficiently, prompting the compressor to run all the time.
Your fridge should run from around 35% of the day to around 85% of the day. A refrigerator that gets opened more frequently has to operate more often to lower the temperature of warmer items, so this amount varies. However, no fridge should run all the time. Try following these steps to diagnose the problem.
Pros of Continuous Fan
Running the fan more often means air in your home circulates faster, leading to everything from more even temperature distribution to faster heating or cooling. Those who use this format find fewer issues with temperature imbalances between floors, for instance.
If the refrigerator runs constantly there might be something caught in the condenser fan motor blade, or the condenser fan motor might be defective. The condenser fan motor draws air over the condenser coils to cool them. The condenser fan motor is located underneath the refrigerator near the back.
However, your refrigerator does not—and should not—run constantly. Every 12 to 15 hours, the refrigeration defrost cycle should begin, which uses a defrost heater to melt any frost that has accumulated on the evaporator coils. Once the defrost cycle is complete, the refrigeration cycle will begin again.
If you are going to be away for a month or less, we recommend the following: Leave the refrigerator running. Leave the temperature controls at the normal settings.
Safe refrigerator tips
Divide leftovers into small, shallow containers for quick cooling in the refrigerator. Cover when food is cooled. Don't overload the refrigerator. Cool air must circulate to keep food safe.
The compressor on a refrigerator or a freezer can run for approx. 45 minutes per hour. Electronically controlled compressors run continuously, but with changed intensity, as needed. This is normal and not a malfunction.
Your refrigerator compressor is responsible for that humming sound. So, if the sound stops for good, or if the sound goes from faint to a constant or very loud humming noise that does not shut off, it may be a sign the compressor is broken or malfunctioning.
Step Three: Most “average” refrigerators run for about eight hours per day. Multiply 8 hours of usage by the number of watts you came up with in step two, or 8 x 960 = 7,680 watts per day, on average. But 7,680 watts is only 7.68 kilowatt-hours.
