Kenmore Refrigerator Error Code R4 R5

The R4 R5 code means the freezer evaporator fan motor is locked and unable to spin. The control board detected that the fan is not rotating when it should be. This fan circulates cold air through the freezer and refrigerator compartments, so the issue needs to be addressed promptly to maintain proper temperatures.

Continued use is not recommended. Without a functioning freezer fan, cold air cannot circulate properly, and both the freezer and fresh food compartments will begin to warm up. Food safety can be compromised quickly, and running the compressor without adequate airflow can also put additional strain on other components.

If the problem is only ice buildup, the repair may cost nothing beyond your time. A replacement freezer evaporator fan motor typically costs between $20 and $80 for the part, plus labor if you hire a technician, which can bring the total to roughly $100 to $250 depending on your area and service rates. Wiring repairs or a control board replacement would fall on the higher end of that range.

Start by checking whether ice buildup or a foreign object is physically blocking the freezer fan blade. If the fan area is clear, inspect the fan motor by turning the blade by hand to see if it rotates freely. A motor that spins freely by hand but still will not run electrically will need to be replaced. Also check the wiring harness connecting the motor to the control board for any damage or loose connections.

A reset may temporarily clear the code, but the error will return if the underlying cause has not been corrected. The control board will continue to monitor the fan motor and will re-trigger the fault as soon as it detects the locked condition again. The root cause, whether ice, a failed motor, or a wiring issue, must be resolved first.
