Quick Kenmore Refrigerator Troubleshooting Not Cooling Guide

How to Fix Kenmore Refrigerator Not Cooling?

Discussed below are 11 reasons why a Kenmore refrigerator won’t cool, plus how you can fix the unit:

1. Condenser Coils Could Be Filthy/Dirty

Heat dissipation is essential for a refrigerator to cool your food and drink. One component that’s critical in dissipating heat in a Kenmore fridge is the condenser coil.

Sadly, the condenser coils become dirty and dusty over time, and when they do, they cannot dissipate heat.

Fix 

Inspect your unit’s condenser coils and clean them if dirty/dusty. You can use a flexible refrigerator coil cleaning brush.

2. The Fridge Could Be Overstuffed with Food

Putting too much food in the fridge blocks the air vents and prevents the cool air from circulating correctly. So, the refrigerator won’t be able to cool properly.

Fix 

Examine your food load and reduce the amount if the fridge unit is overfilled. Also, avoid stacking containers close to one another to improve cold air circulation.

3. The Evaporator Fan Motor Could Be Frosted Over

The evaporator fan is essential in drawing air over and throughout the evaporator coils. The coil, in turn, helps to cool your refrigerator and freezer. But over time, the evaporator fan motor becomes iced, unable to dissipate cool air over the coils. 

Fix 

Test the evaporator fan motor by turning it by hand. If it doesn’t, and it looks icy, test it with a multimeter tester and if it shows no continuity, replace it. But if it does, blow dry it to get rid of ice and adjust the fridge temperature.

4. The Fridge Door Might Be Leaking Air

If you don’t close the fridge door all the way, it’ll allow warm air in, and cold air will leak out, preventing the fridge from cooling. Likewise, if the door gasket/seal is loose or worn out, the door won’t shut properly and will therefore leak.

Fix 

Close the fridge door correctly and replace the door gasket if it’s old or loose.

5. The Condenser Fan Motor Might Be Obstructed or Faulty

The condenser fan motor helps to draw in air and circulate it around the fridge. So, fundamentally, it helps to keep your refrigerator cool.

It can, however, become obstructed by ice or dirty or fail. And if that’s the case, it won’t cool the fridge. 

Fix 

Inspect the condenser fan motor for possible dirt or ice obstruction and clear the block if present. If there’s no obstruction, use a multimeter to test the fan motor for continuity. If it fails the test, replace it.

6. The Temperature Control Thermostat Could Be Malfunctioning

The temperature control thermostat is pivotal in supplying the fan motors and the unit’s compressor with the necessary voltage to run.

For cooling to occur, the compressor and the two fan motors (evaporator and condenser fan motor) must work. So, their failure means no cooling.

Fix 

Test the temperature control thermostat with a multimeter and replace it if it shows no continuity.

7. The Start Capacitor Might Be Defective

The start relay has to be functional for the compressor to run. If it’s faulty, the compressor will fail, and the fridge won’t cool the food supplies.

Fix 

Use a multimeter to examine the start relay for fault. If the start relay doesn’t show continuity, consider replacing it. It’s likely to be faulty.

8. The Thermistor Could Be Faulty

The job of the thermistor is to monitor the Kenmore fridge temperature and relay the information to the main control board. The control board, in turn, enables the evaporator fan motor and the compressor to run and cool the unit.

So, if the thermistor is faulty, all that won’t occur, and there won’t be any cooling. 

Fix 

Using a multimeter, test the thermistor’s continuity. If it shows no continuity, replace it.

9. The Compressor Might Be faulty

The compressor compresses the unit’s refrigerant and redistributes it across the coils. The condenser and evaporator coils won’t cool the fridge unit if it fails.

However, it’s worth noting that the compressor doesn’t fail often. So, it should be one of the last things to check. (www.harveymaria.com)

Fix 

Use a multimeter to test the pin terminals on the compressor. If the pins don’t show continuity, the compressor is faulty. So consider replacing it.

10. The Temperature Control Board Could Be malfunctioning

The temperature control board, like the temperature control thermostat, passes the necessary voltage to the fan motors and compressor.

If it’s faulty, the control board will misdiagnose the voltage information, causing the fan motors and compressor to fail. 

Fix 

Have an expert examine the temperature control board for faults and replace it if it’s malfunctioning.

11. The Main Control Board Might Have Failed

Lastly, your last resort is the main control if the problem is none of the above 10. The problem with a faulty main control board is that it fails the cooling unit and the Kenmore refrigerator ice maker, dispenser, and other parts.

Fix 

If other parts plus the cooling unit are not working, the main control board could be faulty and need a replacement.

My Kenmore Refrigerator Not Cooling But Freezer Is Fine

Sometimes, a Kenmore refrigerator won’t cool while its freezer is fine. That often happens due to these reasons:

• Faulty evaporator fan motor – A defective evaporator fan motor could cause the fridge to fail without affecting the freezer. So, test it with a multimeter and then replace it if it’s faulty.
• Fridge overload – If it’s only the fridge overloaded with food and not the freezer, the freezer will work fine while the refrigerator won’t cool. In such a case, reduce the food to create more room for cold air circulation.
• Excessive Frosting – If the refrigerator compartment is as cold as the freezer, frost will form over the evaporator coils, making them unable to cool the fridge. If so, you need to adjust the fridge temperature and allow the unit to dethaw by unplugging it.
• Defective defrost component – If the defrost timer, thermostat, or control board is bad, the fridge won’t cool until you replace the faulty part.
• Stuck damper control – If the damper control is stuck, it won’t be able to allow cool air to stay in the refrigerator, and so the fridge won’t cool. You’ll need to unstick it if that’s the case.
• Door leak – Ensure you close the fridge door properly and replace the door seal if it’s loose or broken. It could be the reason the unit won’t cool.

Kenmore Refrigerator Not Cooling After Power Failure

How can a damaged door gasket affect the cooling of a refrigerator?

A damaged door gasket can significantly impact the cooling efficiency of a refrigerator. The primary function of a refrigerator door gasket is to create an airtight seal around the frame of the appliance. This seal is essential as it prevents the escape of cold air and blocks the entry of warm air into the refrigerator compartment.

When a door gasket is twisted or torn, it fails to form a proper seal. As a result, gaps can form along the edges, allowing warm air from the surroundings to infiltrate the refrigerator. The introduction of warm air disrupts the optimal cooling environment inside the appliance, leading to multiple issues.

Firstly, the warm air entering through the damaged gasket causes the refrigerator’s internal temperature to rise. This rise in temperature can hinder the refrigerator’s ability to cool and maintain the desired cold temperature needed for food storage. It forces the refrigerator’s cooling system to work harder and for longer durations to compensate for the warm air infiltration.

Secondly, when warm air enters, it counteracts the refrigerator’s cooling cycle. The cooling system cools the air inside the refrigerator, and if warm air continuously infiltrates, it requires more energy and time to achieve the desired temperature. This can result in uneven cooling, with some areas of the refrigerator being warmer than others.

Furthermore, the presence of warm air can lead to moisture accumulation inside the refrigerator. As warm air cools down, it releases moisture, which can condense on various surfaces. Excessive moisture within the refrigerator can negatively impact the freshness and longevity of stored food items, potentially causing them to spoil more quickly.

In summary, a damaged door gasket compromises the refrigerator’s cooling efficiency by allowing the entry of warm air. This disrupts the internal temperature, hampers the cooling system’s effectiveness, and may lead to uneven cooling and moisture accumulation.

How can I determine if the condenser fan motor is defective?

To determine if the condenser fan motor is defective, there are a few steps you can follow. First, make sure to inspect the fan blade for any obstructions that may be preventing it from spinning freely. If you notice any debris or objects in the way, it is important to remove them carefully.

Next, try manually turning the fan motor blade by hand. If you encounter any resistance or if the blade does not spin freely, it is a strong indication that the condenser fan motor may be defective and in need of replacement.

If you find no obstructions and the fan blade spins freely, the next step is to test the fan motor for continuity using a multimeter. A multimeter is a device that can measure the electrical current flowing through a circuit. By checking for continuity, you are essentially determining if there is an uninterrupted path for the electrical current to flow within the fan motor.

To perform this test, ensure that the power supply to the condenser fan motor is turned off. Then, disconnect the electrical wires attached to the fan motor, making note of which wire goes where. Set your multimeter to the continuity or resistance mode and touch the meter probes to the appropriate wire connections on the fan motor.

If the multimeter registers continuity, that means the fan motor is functioning properly, and it is not the cause of any issues. However, if the multimeter does not show continuity, it is a clear indication that the condenser fan motor is defective and should be replaced.

In summary, to determine if the condenser fan motor is defective, inspect the fan blade for any obstructions, attempt to turn the fan motor blade manually, and use a multimeter to test for continuity. If the blade does not spin freely or if there is no continuity in the motor, it is recommended to replace the condenser fan motor.

What is the recommended temperature range for the freezer and refrigerator compartments?

The recommended temperature range for the freezer compartment is between 0 and 5 degrees Fahrenheit (-18 to -15 Celsius). For the refrigerator compartment, the recommended temperature range is between 34 and 40 degrees Fahrenheit (1 to 5 Celsius).

How do dirty condenser coils affect the cooling of a Kenmore refrigerator?

Dirty condenser coils have a detrimental effect on the cooling efficiency of a Kenmore refrigerator. Typically located underneath the refrigerator, these coils play a crucial role in dissipating heat as refrigerant passes through them. When the condenser coils become dirty, their ability to effectively dissipate the heat is compromised. As debris accumulates on the coils, the refrigerator’s overall efficiency decreases, leading to a situation where the refrigerator works harder to achieve the desired cooling temperature.

As the coils become increasingly dirty, the refrigerator struggles to maintain the ideal temperature setting. This is because the accumulated debris inhibits the coils’ ability to transfer heat properly. Consequently, the refrigerator’s cooling system is forced to work overtime, consuming more energy than necessary. Ultimately, if the condenser coils remain significantly dirty, the refrigerator will no longer be able to maintain the proper temperature, resulting in reduced cooling performance.

To address this issue, it is crucial to periodically check the condenser coils for dirt and debris accumulation. If dirty, cleaning the condenser coils becomes imperative to restore the refrigerator’s cooling efficiency. By removing the built-up debris and ensuring the coils are clean, the refrigerator can efficiently dissipate heat, enabling it to cool more effectively and maintain the desired temperature.

– Fridge overload: If the refrigerator is overloaded with food, but the freezer is not, it can negatively impact the fridge’s cooling ability. In such cases, it is important to reduce the amount of food stored in the refrigerator to allow for proper air circulation and cooling.

– Excessive Frosting: If the refrigerator compartment is as cold as the freezer, it can lead to the formation of frost on the evaporator coils, preventing them from effectively cooling the fridge. To address this, you can adjust the fridge temperature and allow the unit to defrost by unplugging it.

– Defective defrost component: A malfunctioning defrost timer, thermostat, or control board can also cause the refrigerator to stop cooling properly. If any of these components are found to be faulty, they will need to be replaced to restore proper cooling functionality.

– Stuck damper control: A stuck damper control can restrict the flow of cool air into the refrigerator compartment, resulting in inadequate cooling. In such cases, you can try to unstick the damper control to restore proper airflow.

– Door leak: It is important to ensure that the refrigerator door is closed properly, as a loose or broken door seal can lead to air leaks and inadequate cooling. If the seal is damaged, it should be replaced to ensure a proper seal and efficient cooling.

While the above explanations cover common issues that can cause a refrigerator not to cool properly, in some cases, the problem may be more complex. If all the refrigeration components seem to be working, and none of the above issues are present, there may be a restriction or leak in the refrigeration system. To confirm this, it is advisable to consult a qualified technician who can remove the evaporator cover and examine the frost pattern on the coil. If there is frost or ice buildup in only one section of the coil, it suggests a potential restriction or leak in the system. It is important to note that repairing such issues can be expensive and may require the expertise of a professional technician.
