I have a Kenmore Elite model 795.74015.411 refrigerator that suddenly stopped cooling last night. I do hear fan(s) running when doors are closed. There are no error codes. Unit is 2 years old.

Is the freezer cold?
Cause 1
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.
Cause 2
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.
Cause 3
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.
Cause 4
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.
Cause 5
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.
Cause 6
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.
Cause 7
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.
Cause 8
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.
Cause 9
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.
Cause 10
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.

No. Both the refrigerator and freezer are not cooling.
These compressors are Samsung inverter type. They only have two wires on the compressor and don't use a current or start relay.
neither freezer or frig cooling but compresser and condenser fan is running and all is clean in back.

My Kenmore Elite 795.74053.411 stopped cooling 2 days ago. This model has an LG compressor that is known to break down. My unit is only 5 years old. Sears diagnosed a defective compressor.

I have the same problem ‘ it still not fixed, Sears said it’s waiting for part, is there any one that can help. . ? It’s only 1 and a half year old : warranty expired
par carlos mario espinosa
@carlos mario espinosa please be aware that if the warranty is expired repairs can become costly. Contact a local appliance repair shop and see what they'll charge. Repair shops have their own suppliers (United Refrigeration, etc) to get parts from. If it is only 1.5 yrs old then it may not actually be the compressor is bad, but rather the start components. If it IS the compressor then a repair shop will be able to give you an estimate.

I have a kenmore Elite model 795 74015 411 refrigerator which just stop cooling. I called a repair guy, and he said, that my compressor was done. I payed him $75 for that. When I talked to sears, they are willing to pay for the parts, but they want $709 for labor. I'm totally stuck !!
