Force Defrost Mode in Kenmore Refrigerator

By | November 16, 2021

The electronic control board controls the defrost system in that model of refrigerator so it doesn’t have an electro-mechanical timer for defrost. Here’s the procedure to use the forced defrost mode:

  1. Hold the refrigerator door light switch closed.
  2. Press the Refrigerator Temperature DOWN /- keypad 3 times consecutively.
    Note: The 3 keystrokes must be consecutive and within 10 seconds.
  3. Release the refrigerator door light switch.
  4. The control will display F- d to confirm entry into the Forced Defrost Mode.
  5. Entry is confirmed by pressing the Refrigerator Temperature DOWN /- key once more. The unit is off and in
    the Defrost Mode.
    Note: All control functions will be turned off (Compressor, Defrost, Evaporator Fan, the damper will remain in its
    current position).
  6. The control will default to the short run period test.
    Note: You can toggle between the S Short and L Long test mode by pressing the Refrigerator Temperature UP /+
    Key. Long Test mode is used for factory test and should not be used in the field.
  7. Once the desired mode is displayed, confirm the forced defrost by pressing the Refrigerator Temperature
    DOWN /- Key once. The defrost will begin immediately and the display will return to a normal operating display
    with set point values.
  8. Close the Refrigerator door(s). You are in the defrost mode.
    Note: Forced Defrost mode can be exited at any time prior to step 7 by closing the Refrigerator Door(s).
