Kenmore Refrigerator Not Cooling
01 – Condenser Coils are Dirty
The condenser coils are usually located under the refrigerator. They dissipate heat as refrigerant passes through them. If the condenser coils are dirty, they won’t dissipate the heat effectively. As debris builds up on the coils, the refrigerator becomes less efficient, causing the refrigerator to work harder to cool down. If the coils are significantly dirty, the refrigerator will not be able to maintain the proper temperature. Check the condenser coils to determine if they are dirty—if the condenser coils are dirty, clean them.
02 – Freezer or refrigerator temperature is set too high
Verify the freezer temperature is set between 0 and 5 degrees Fahrenheit (-18 to -15 Celsius). Verify the refrigerator temperature is set between 34 and 40 degrees Fahrenheit (1 to 5 Celsius). After reseting the temperature wait 24 hours for the temperature to adjust appropriately.
03 – Kenmore Refrigerator Condenser Fan Motor
The condenser fan motor draws air though the condenser coils and over the compressor. If the condenser fan motor is not working properly, the refrigerator won’t cool properly. To determine if the fan motor is defective, first check the fan blade for obstructions. Next, try turning the fan motor blade by hand. If the blade does not spin freely, replace the condenser fan motor. If no obstructions are present and the fan blade spins freely, use a multimeter to test the fan motor for continuity. If the condenser fan motor does not have continuity, replace it.
04 – Kenmore Refrigerator Evaporator Fan Motor
The evaporator fan motor draws air over the evaporator (cooling) coils and circulates it throughout the refrigerator and freezer compartments. Some refrigerators have more than one evaporator fan motor. On refrigerators with only one evaporator, the evaporator is located in the freezer compartment. If the evaporator fan is not working, it will not circulate the cold air to the refrigerator compartment. If this occurs, the freezer may still get cold, while the refrigerator will not get cold. To determine if the evaporator fan motor is defective, try turning the fan blade by hand. If the fan blade does not turn freely, replace the fan motor. Additionally, if the motor is unusually noisy, replace it. Finally, if the motor does not run at all, use a multimeter to test the motor windings for continuity. If the windings do not have continuity, replace the evaporator fan motor.
05 – Kenmore Refrigerator Door Gasket
A refrigerator door gasket should form an airtight seal around the appliance’s frame to keep the cold air in and the warm air out. If the door gasket is twisted or torn, gaps can form that will allow warm air in, resulting in the refrigerator not cooling properly. Inspect the door gasket for any damage and replace with a new one if necessary.
06 – Incoming Power Problem
Ensure plug is tightly pushed into electrical outlet and outlet is supplying power. Check fuses or circuit breaker if needed. It is best to have the refrigerator on a seperate dedicated circuit. If the refrigerator is connected to a ground fault receptacle it may need to be plugged into a regular receptacle. Using a ground fault receptacle for a refrigerator is not recommended.
07 – Kenmore Refrigerator Damper Control Assembly
On many refrigerator models, a damper control assembly is used to control the air flow from the freezer compartment to the refrigerator compartment to maintain the appropriate air temperature. If a refrigerator is not cooling properly, it’s possible the damper door is stuck closed. Inspect the damper control assembly for any malfunction and replace it with a new one if necessary.
08 – Sealed System Problem
If all the refrigeration components seem to be working, but the refrigerator is not cooling properly there may be a restriction or leak in the refrigeration system. To determine this, you will need to remove the evaporator cover and observe the frost pattern on the coil. Note: The compressor, condenser and evaporator fans should all be running, and the condenser coil should be clean and have good air flow. There should be light frost on most of the coil. If the coil has frost or ice buildup in only one section, there is likely a restriction or leak in the system. This repair is expensive (maybe cost prohibitive) and should be diagnosed and repaired by a qualified technician.
09 – Kenmore Refrigerator Start Relay
The start relay works in conjunction with the start winding to start the compressor. If the start relay is defective, the compressor may sometimes fail to run or may not run at all. As a result, the refrigerator will not be cold enough. To determine if the start relay is defective, use a multimeter to test it for continuity between the run and start terminal sockets. If the start relay does not have continuity between the run and start terminal sockets, replace it. In addition, if the start relay has a burnt odor, replace it.
10 – Kenmore Refrigerator Control Board
The control board might be defective. However, this is almost never the cause. Before replacing the control board, test all of more commonly defective parts. If none of the other components are defective, consider replacing the control board.
11 – Kenmore Refrigerator Temperature Control Thermostat
The temperature control thermostat directs voltage to the compressor, evaporator fan motor, and condenser fan motor (if applicable). If the temperature control thermostat is not working properly, it may prevent the refrigerant system from running. To determine if the thermostat is defective, rotate the thermostat from the lowest setting to the highest setting and listen for a click. If the thermostat clicks, it is not likely defective. If the thermostat does not click, use a multimeter to test the thermostat for continuity. If the temperature control thermostat does not have continuity at any setting, replace it.
12 – Kenmore Refrigerator Inverter Board
The inverter board is the component that cycles the compressor on and off. You can use a multimeter to test if power is reaching the compressor. If no power is reaching the compressor, the inverter board is likely defective and should be replaced.
13 – Kenmore Refrigerator Defrost Heater Assembly
The defrost heater assembly turns on several times throughout the day to melt away any frost that may have accumulated on the evaporator coils. If the defrost heater assembly is defective, the defrost system will not work, and frost will continue to accumulate on the evaporator coils. This will result in the refrigerator not cooling properly. To determine if the defrost heater is defective, use a multimeter to test it for electrical continuity. If the defrost heater does not have continuity, replace it.
14 – Kenmore Refrigerator Start Capacitor
The start capacitor provides a boost of power to the compressor during start-up. If the start capacitor isn’t working, the compressor may not start. As a result, the refrigerator will not cool. To determine if the start capacitor is defective, test it with a multimeter. If the start capacitor is defective, replace it.
15 – Kenmore Refrigerator Defrost Thermostat
The defrost thermostat monitors the temperature of the evaporator coils. When the coils drop below a set temperature, the thermostat contacts close to allow power to flow to the defrost heater during the defrost cycle. In the defrost cycle, the defrost heater melts away any frost that may have accumulated on the evaporator coils. If the defrost thermostat is defective, the defrost heater may not activate. This will cause the evaporator coils to frost over resulting in the refrigerator not cooling properly. To determine if the defrost thermostat is defective, use a multimeter to test it for electrical continuity. If the defrost thermostat does not have continuity when it reaches the low temperature of its operating range, replace it.
16 – Kenmore Refrigerator Thermistor
The thermistor monitors the refrigerator temperature and sends the temperature reading to the control board. The control board regulates power to the compressor and evaporator fan based on the thermistor readings. If the thermistor is defective, the compressor and evaporator fan may not run when necessary. As a result, the refrigerator will not be cold enough. To determine if the thermistor is defective, test it with a multimeter. The thermistor resistance should change in conjunction with the refrigerator temperature. If the thermistor resistance does not change, or the thermistor does not have continuity, replace the thermistor.
17 – Kenmore Refrigerator Temperature Control Board
The temperature control board provides voltage to the compressor and fan motors. If the temperature control board is defective, it will stop sending voltage to the cooling system. However, this is not a common occurrence. Control boards are often misdiagnosed—before replacing the control board, first test all of the more commonly defective components. If none of the other components are defective, consider replacing the temperature control board.
18 – Kenmore Refrigerator Compressor
The compressor is a pump which compresses the refrigerant and circulates the refrigerant through the evaporator and condenser coils. If the compressor is not working, the refrigerator won’t cool. However, this is rarely the case. Before replacing the compressor, first check all of the more commonly defective parts. If you have determined that all of the other components are working properly, check the compressor. Use a multimeter to test the continuity between the electrical pins on the side of the compressor. If there is an open circuit, the compressor is likely defective. If the compressor is defective, it must be replaced by a licensed technician.
19 – Kenmore Refrigerator Main Control Board
The main control board might be defective. However, this is almost never the cause. Before replacing the main control board, test all of more commonly defective parts. If none of the other components are defective, consider replacing the main control board.
20 – Kenmore Refrigerator Start Device
A start device, like a start relay, works in conjunction with the start winding to start the compressor. If the start device is defective, the compressor may sometimes fail to run or may not run at all. As a result, the refrigerator will not be cold enough. To determine if the start device is defective, use a multimeter to test it for continuity between the run and start terminal sockets. If the start device does not have continuity between the run and start terminal sockets, replace it. In addition, if the start device has a burnt odor, replace it.
