Kenmore Washer Error Code F15

F15 on a Kenmore washer means the Motor Control Unit (MCU) has detected an internal over-temperature condition. When this happens, the MCU sends a fault signal to the Central Control Unit (CCU), which then resets the MCU. It is a built-in protective response to prevent heat damage to the motor control electronics.

It is not recommended to continue running the washer while F15 is active. The error indicates the motor control electronics have reached an unsafe temperature, and continuing to operate the unit could cause permanent damage to the MCU or related components. Allow the unit to cool and diagnose the root cause before running another cycle.

Repair costs vary depending on the root cause. If the issue is simply a ventilation problem, there may be no parts cost at all. If the MCU needs replacement, parts and labor can range from $150 to $350 or more depending on the specific model and service rates in your area. A failing wash motor can add additional cost to that estimate.

Start by checking the installation environment: verify the washer has proper ventilation and is not located near a heat source. If the environment is fine, inspect the MCU for signs of heat damage and check the wash motor for abnormal current draw or resistance. Depending on what is found, the fix may be as simple as repositioning the unit or as involved as replacing the MCU or wash motor.

The CCU automatically attempts to reset the MCU when F15 is triggered, but this does not fix the underlying cause of the overheating. If the root cause is not addressed, such as poor ventilation or a failing component, the error will return. A reset may temporarily clear the code, but a proper diagnosis is needed to prevent recurring faults.
