Remember that your new refrigerator will run longer than your old one due to its high-efficiency motor. Your new refrigerator has been designed with a high-efficiency compressor to optimize energy and better regulate temperatures to match cooling demand.
Internal Temperature is Too High
If the freezer or refrigerator temperature is too high, the refrigerator runs constantly in an attempt to keep the interior cool. Even if the refrigerator temperature is within the right range, a high freezer temperature can still warm the refrigerator, leading to constant running.
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 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.
Why is my new fridge making a loud noise? The evaporator fan motor may be going bad. The condenser fan motor may be overheating due to constant heat and dust. The evaporator motor fan blade may have an obstruction or be damaged. The condenser motor fan blade may have an obstruction or be damaged.
If your refrigerator doesn't stop running, it can lead to higher electricity bills and reduce the lifespan of your appliance by months or even years. Several potential causes could be making your fridge run continuously: dirty condenser coils, a faulty defrost heater, and problems with the defrost thermostat.
The noise comes from the compressor of the refrigerator when the compressor gets ON then you will listen to that noise. It is common so before purchasing go with the refrigerator which produces less noise. Some of the refrigerators feature this functionality.
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.
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.
When you add food to the refrigerator, it technically reduces the space inside that must be cooled. The appliance doesn't have to run as long because the space is filled. An empty refrigerator, however, creates a larger space to cool. As a result, the compressor runs a lot to create a consistent temperature setting.
Once your fridge has been safely moved into the kitchen of your new home and is in the desired position, you should let it stand unplugged, in an upright position, for at least 4 hours to allow its compressor oil to settle.
Frigidaire Refrigerator Main Control Board
If the refrigerator runs constantly, the main control board might be defective. A few times a day the control board is supposed to turn off the cooling system and turn on the defrost heater to melt away any frost that may have accumulated on the freezer evaporator coils.
So, how often should a fridge/freezer cycle on and off? On average, most refrigerators run for about 45 minutes to an hour before taking a break. This means the compressor is actively cooling your food for around 80–90% of the day.
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.
Shutting off the power to the refrigerator will give all of its systems—including the compressor—time to reset. Power down your refrigerator by unplugging it from the wall or shutting off the circuit breaker connected to the fridge. Leave the unit unplugged for five to ten minutes.
Refrigerator Temperature is Too High
If the temperature is set too high, the refrigerator will run constantly in an effort to keep cool. For optimum cooling that doesn't overwork the refrigerator, LG recommends a temperature setting of 37℉ for the refrigerator and 0℉ for the freezer.
One of the most common causes of a refrigerator constantly running is a faulty defrost timer. After the compressor in the refrigerator has run for 8 to 10 hours over a set period, the defrost timer will start a defrost cycle, which shuts the compressor down to essentially give it time to defrost.
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.
For example, most people have units that operate (or “run”) for about eight total hours per day. But, if you do things like clean the coils, position the appliance correctly, keep it well-maintained, and set the right temperature, you can reduce the amount of time it runs to less than eight hours per day.
If your GE refrigerator runs constantly, first check its temperature settings. If the internal temperature is set too high, the refrigerator has to run constantly to keep cool. GE recommends setting the refrigerator's internal temperature within the range of 34-42℉ and the freezer between -5-8℉.
Your Fridge Is Extra Quiet
If so, it could be an indication that something is wrong with it. While a quieter fridge can be a good thing, too much silence could be a sign that the compressor is not running. If you notice this, have a specialist check your refrigerator.
Our Top Pick: LG produces excellent refrigerators that perform well in our tests and receive high satisfaction ratings from consumers, including our survey participants. The Smart French Door Refrigerator with Dual Ice Maker stands out for its simple, user-friendly design and customizable features.
One of the most common reasons a Whirlpool refrigerator runs constantly is because the internal temperature is too high. If your fridge isn't set to the manufacturer's recommended temperature settings, it will run constantly in an attempt to reach the desired temperature.
A minimal running noise is completely normal and is an indication that the air circulation is balanced and your fridge is functioning properly. If your fridge is making a disturbing amount of noise and you think it may have a technical problem, please find our contact details by clicking here.
Give it a week of normal use. The harness that runs through the door may not be properly seated in new refrigerators. As the doors are opened and closed on a daily basis, the harness will properly seat itself. If the noise continues after a week, remove the hinge cover and check the wire harness.
