Kenmore Washer Error Code F15

F15Kenmore Washer

What this code means

MCU thermal trip error — MCU has an internal over-temperature condition and sends signal to CCU which resets the MCU.

First step from the service manual

Check for proper installation, verify the unit is not located near a source of heat and has proper ventilation.

Next steps: diagnose the root cause

1
Verify the error code is active

Power cycle the unit and see if the code returns. If it does, the fault is persistent and requires diagnosis.
